| 2:28a | [Botany • 2024] Impatiens beipanjiangensis (Balsaminaceae) • A New Species from Guizhou, China
Abstract Impatiens beipanjiangensis Jian Xu & H. F. Hu (Balsaminaceae), a new species of Impatiens subg. Clavicarpa discovered in Guizhou, China, is described and illustrated in this study along with its molecular phylogenetic analysis. I. beipanjiangensis is similar to I. liboensis, I. chishuiensis and I. clavigera in morphology, but I. tubulosa has the closest relationship to it. However, there are various ways in which the new species can be easily distinguished from these four species: Inferior nodes swollen rhizoid, pale green and with hooked outer sepals, longer lateral united petals, subovate auricle, deeper lower sepal and shorter spur that is reflexed towards the lower sepal. Furthermore, I. beipanjiangensis is distinguished from other Impatiens species, based on morphological, micromorphological and palynological evidence and molecular data (PP 0.967). Key words: Balsaminaceae, Flora of China, morphology, phylogeny, taxonomy
Impatiens beipanjiangensis Jian Xu & H.F. Hu, sp. nov. Diagnosis: This species is similar in morphology to I. liboensis, I. chishuiensis and I. clavigera and is close in phylogeny to I. tubulosa. Their leaf margin with crenate and fimbriae, raceme, stamens 5, ovary clavate, capsule hammer-shaped. However, it is different in the following aspects: inferior nodes swollen rhizoid, pale green and with hooked outer sepals, longer lateral united petals, subovate auricle, deeper lower sepal and shorter spur that is reflexed towards the lower sepal. Etymology: The specific epithet “beipanjiangensis” refers to the river basin of the type specimen, Panzhou City (Beipanjiang River Basin), Guizhou, China. Vernacular name: The Chinese name is “Bēi Pán Jiāng Fèng Xiān Huā” (北盘江凤仙花).   Hong-Fen Hu, Jian Xu, Ming-Tai An, Ying Guo and Jia-Wen Yang. 2024.

| 2:35a | [Entomology • 2024] Hoplitis (Hoplitis) onosmaevae • A New osmiine Bee (Hymenoptera: Anthophila: Megachilidae) with a spectacular Geographic Disjunction
Abstract A new osmiine bee species, Hoplitis (Hoplitis) onosmaevae sp. nov. (Megachilidae), is described. So far, this species is exclusively known from the Mercantour National Park in the southwestern French Alps and from mountainous ranges in Turkey and northern Iraq, two areas separated by at least 2000 km. Phylogenetic analyses based on mitochondrial and nuclear genes revealed that H. onosmaevae is closely related to H. adunca (Panzer, 1798), H. benoisti (Alfken, 1935) and H. manicata (Morice, 1901). Hoplitis onosmaevae is presumably narrowly oligolectic and harvests pollen only on flowers of Onosma L. (Boraginaceae). It has a particularly long proboscis, which is probably an adaptation to collect nectar from the long-tubed flowers of this plant genus. The females collect pollen by buzzing the Onosma flowers, a rare behavior in megachilid bees. The species nests in insect burrows in dead wood, similar to H. adunca and H. manicata but unlike other closely related representatives of the subgenus Hoplitis, suggesting a single origin of nesting in dead wood and hollow stems in this lineage. In France, H. onosmaevae inhabits alpine steppe-like habitats close to forests and appears to be extremely local, since only two populations are currently known. The conservation status of this extremely rare bee species in Europe is discussed. Key Words: Anthophila, Apiformes, Hoplitis, Onosma, osmiine bees, buzzing, conservation, France, Iraq, Turkey
Hoplitis (Hoplitis) onosmaevae Aubert, sp. nov. Diagnosis: In most species of Hoplitis (Hoplitis), the length of the proboscis is at most one-third as long as the body. Only H. linguaria, H. holmboei, H. homalocera and H. semilinguaria have a longer proboscis, which reaches about half of the body length. Hoplitis onosmaevae possesses an even longer proboscis, which is approximately as long as the body (Fig. 3). In both sexes of H. holmboei and H. homalocera, the vertex is comparatively short (ocelloccipital distance less than two ocellar diameters) and, when seen in front view, not elevated behind ocelli, but regularly rounded across its width; in H. onosmaevae the vertex is longer (ocelloccipital distance about ... Etymology: The species epithet onosmaevae refers to the assumed close association with plants of the genus Onosma (see section on pollen hosts below) and to Maëva Gardenat, to whom the first author wishes to dedicate this species. Matthieu Aubert, Andreas Müller and Christophe Praz. 2024. A New osmiine Bee with a spectacular Geographic Disjunction: Hoplitis (Hoplitis) onosmaevae sp. nov. (Hymenoptera, Anthophila, Megachilidae). Alpine Entomology. 8: 65-79. DOI: 10.3897/alpento.8.118039 Résumé: Une nouvelle espèce d’abeille appartenant à la tribu des Osmiini, Hoplitis onosmaevae sp. nov. (Megachilidae), est décrite. Elle est à ce jour connue du Parc national du Mercantour dans le Sud des Alpes françaises et de zones montagneuses de Turquie et du Nord de l’Irak, deux aires distantes de plus de 2000 km. Des analyses phylogénétiques de gènes mitochondriaux et nucléaires indiquent que cette nouvelle espèce est apparentée à H. adunca (Panzer, 1798), H. benoisti (Alfken, 1935) et H. manicata (Morice, 1901). Hoplitis onosmaevae est certainement oligolectique, spécialisée pour la récolte du pollen sur les fleurs d’Onosma L (Boraginaceae). Elle est caractérisée notamment par un proboscis très allongé, qui est probablement une adaptation à la collecte du nectar dans les fleurs de ce genre botanique. Les femelles en exploitent le pollen en les faisant vibrer («buzzing»), comportement rare au sein de la famille des Megachilidae. Il a été observé que cette nouvelle espèce nidifie dans des galeries existantes dans le bois mort, à l’instar de H. adunca et de H. manicata, mais contrairement à d’autres représentants du sous-genre Hoplitis, ce qui suggère une origine unique de l’emploi du bois mort et des tiges creuses en tant que substrat de nidification au sein de ce groupe. En France, H. onosmaevae semble extrêmement localisée : elle n’a été trouvée que sur deux stations, correspondant à des habitats d’altitude d’affinité steppique, non loin de boisements. Son statut de conservation en Europe est discuté. | ||||||||

Abstract Allium ulleungense (subg. Anguinum, Amaryllidaceae), from Ulleungdo Island, Korea, is described as a new species. It is clearly distinguished from its close relatives, A. microdictyon and A. ochotense, by its broader leaves and larger whitish perianth and by its diploid chromosome number, which is 2n = 2x = 16. The lengths of the chromosomes range from 11.3 to 15.75 μm. Molecular phylogenetic analyses using nuclear and chloroplast markers also clearly indicate that A. ulleungense is genetically distinct from other species of the subg. Anguinum. Keywords: Amaryllidaceae, Anguinum, Allium ulleungense, Ulleungdo Island, Korea
Allium ulleungense H. J. Choi & N. Friesen, sp. nov. Etymology: The specific epithet, “ulleungense,” is based on the name of the location, Ulleungdo Island, where Allium ulleungense was discovered.

| 4:23a | [Botany • 2024] Behria leonis (Asparagaceae: Brodiaeoideae) • A New Cryptic Species from the Baja California peninsula, Mexico
Abstract Behria is a genus of petaloid geophytes endemic to the Cape Region of Baja California Sur, Mexico. It belongs to the Milla clade within the subfamily Brodiaeoideae of the Asparagaceae family. Currently, Behria tenuiflora is the only recognized species within this genus. In our methodological approach, we considered two distinct floral morphotypes: Group A consists of populations found at lowland elevations (10–150 m), while Group B comprises plants growing at mid to high elevations (400–2060 m). The aim of our study was to investigate whether there are discernible morphological differences and correlations with climate variables between Behria Group A and Group B. To address this, we measured nine quantitative characters for 94 plants from seven populations of Behria tenuiflora. Our findings revealed statistically significant differences (P < 0.05) in pedicel length, perianth length, perianth base diameter, and perianth aperture diameter of the analyzed Behria groups. Based on these results, we propose the recognition of Behria leonis as a new species. Additionally, we provide a morphological key for distinguishing Behria and Bessera genera, along with illustrations, a distribution map, and photographs.

Behria leonis E. Gándara & Ruiz-Sanchez sp. nov., TYPE:—MEXICO. Baja California Sur: Municipio, La Paz, Sierra de La Laguna, Km 11 brecha a Termopilas, Ejido San Antonio, adelante de San José del Rancho, 23.702688, -109.985759, elevation 690 m, 23 September 2021, deciduous tropical forests, E. Gándara et al. 3299 (holotype IBUG!). Behria leonis differs from B. tenuifolia in having a longer perianth (2.2–3.2 cm vs. 1.7–2.6 cm) , a wider perianth aperture (8.5–14.3 mm vs. 3.1–6.4 mm), a narrower perianth base (3.9–6.3 mm vs. 4.6–8 mm), hypocrateriform flowers instead of tubular flowers, and perianth slightly saccate at the base vs. perianth prominently saccate. Etymology:—The species epithet “leonis” is named in honor of the Mexican botanist José Luis León de la Luz. He is a highly regarded researcher who retired from CIBNOR (Centro de Investigaciones Biológicas del Noroeste S.C.) and is known as the foremost botanist in Southern Baja California Sur. Throughout his career, José Luis León de la Luz has extensively collected thousands of plants in the region and has made significant contributions to the field of botany. Notably, he played a role in neotypifying Behria tenuiflora, ensuring a standardized reference specimen for future studies. Furthermore, he collaborated on projects involving the extraction and identification of alkaloids from this species, contributing to the understanding of its chemical composition.

| 4:33a | [Arachnida • 2024] Urophonius trewanke • A New Species of Genus Urophonius Pocock, 1893 (Scorpiones: Bothriuridae), from Andean Mauline Chilean Forests, with a phylogenetic re-analysis of the Genus
Abstract Urophonius trewanke sp. nov. is described from the Mauline Andean woods of northern Chilean Patagonia. This species belongs to the granulatus species group, which includes the most basal species within the genus. This species is only active in summer as in all species of its group. We performed a phylogenetic analysis of the genus Urophonius based on morphological characters to establish the position and relationships of the new species in the genus. Key Words: Bothriuridae, Chile, Mauline woods, new species, phylogeny
Urophonius trewanke sp. nov. Diagnosis: Urophonius trewanke sp. nov. is most closely related to U. tregualemuensis from south-central Chile (Fig. 2a). Both species can be easily separated by their pigment pattern; in U. trewanke sp. nov. the dorso-submedian spots of tergites are poorly developed, being reduced to small triangles in the posterior half of the segment (Figs 4a, 5a), whereas in U. tregualemuensis, these spots are much more developed, occupying almost the whole median part of the segment (Fig. 5b). ... Etymology: The specific epithet “trewanke” is a noun in apposition meaning scorpion in Mapungudun, the language of the Mapuche people, the original inhabitants from most parts of southern and central Chile.

| 6:27a | [Ichthyology • 2018] Copionodon elysium • A New Species of Copionodon (Siluriformes: Trichomycteridae) lacking a free orbital rim
ABSTRACT A new species of the copionodontine genus Copionodon is described from the upper reaches of a tributary to the rio Paraguaçu in the Diamantina Plateau, Bahia State, northeastern Brazil. This species represents the northernmost occurrence of the subfamily yet known. The new species can be readily recognized by its large eye without a free orbital rim. Other characters such as the entirely cartilaginous second hypobranchial, and the uniformly broad irregular midlateral dark band further diagnose the new taxon. Its particular combination of characters is superficially intermediate between Copionodon and Glaphyropoma. Detailed analysis, however, indicates that it forms a monophyletic group with species of Copionodon and therefore it should be included in that genus. Key-words: Chapada Diamantina; Endemicity; New taxon; Rio Paraguaçu; Systematics; Taxonomy    Copionodon elysium, new species Diagnosis. Distinguished from all other copionodontine catfishes by the large eye without a free orbital rim (Figs. 1, 2; vs. large eyes and free orbital rim in Copionodon spp. or with small eyes but without a free orbital rim in Glaphyropoma spp.). Also, uniquely diagnosed in the subfamily by the second hypobranchial entirely cartilaginous (Fig. 3; vs. presence of a conical ossification cap in the anterolateral corner of the second hypobranchial in other copionodontines) and the reduced or vestigial adipose fin in adults, resulting in a dorsal profile of the caudal peduncle almost straight (Fig. 1; vs. caudal peduncle dorsally convex as a result of the well-developed adipose fin). Further distinguished from congeners by the thin upper and lower lips, with lower lip not flattened ventrally, continuous and not split in two halves by medial depression (Fig. 2b; vs. broader lips and presence of median constriction on lower lip), mouth inferior, located close to anterior margin of snout (vs. mouth distinctly ventral, located posterior to anterior margin of snout), and by the posteriorly-positioned dorsal fin (predorsal distance 56.7-61.7 % of SL vs. 46.0-55.0 % of SL). The new species is also distinguished by its color pattern, with an uniformly broad midlateral dark (Fig. 1; vs. narrow dark band in C. pecten, somewhat broad and asymmetrical dark band in C. lianae, or absence of dark lateral band in remaining copionodontines). Copionodon elysium further differs from C. pecten by the smaller interopercular patch of odontodes, distant from lower lip anteriorly and not reaching opercular aperture (Fig. 2b; vs. interopercular patch of odontodes large, extending from near lower lip anteriorly to beyond pectoral-fin insertion posteriorly) and longer barbels, with maxillary barbel usually reaching pectoral-fin origin and rictal one extending beyond midlength of interopercular patch of odontodes (vs. maxillary barbel reaching posterior ¼ of length of interopercular patch of odontodes and rictal reaching anterior ¼ of length of interopercular patch of odontodes). From the species of Glaphyropoma, the new taxon further differs by a series of characters, including the broad hypobranchial (Fig. 3; vs. slender), the caudal fin bilobed (Fig. 1; vs. truncate), the toothed portion on dentary not reaching the coronoid process (Fig. 4; vs. reaching coronoid process), and the presence of asymmetrical spatulate teeth in jaws (Fig. 4; vs. all teeth symmetrically spatulate).
 Geographical distribution. Copionodon elysium is known exclusively from riacho Águas Claras, a stream of approximately 6 km, tributary of rio Mucugezinho, itself a tributary of rio Santo Antonio, upper rio Paraguaçu basin, Chapada Diamantina, Bahia State, Brazil (Fig. 6). Ecological notes. The Águas Claras stream is perennial and torrential in the rainy season. Its headwaters are around 1000 m above sea level and it runs on the western slopes of the Sincorá Range, partly within the Chapada Diamantina National Park. The population has a patchy distribution in the stream, with individuals concentrating in certain stretches and entirely absent in others. Copionodon elysium was sampled in slow-flowing stretches over solid rock bottom or boulders, with riffles and shallow pools 10-30 centimeters deep and 1-3 meters wide (Fig. 7), with water transparent and tea-stained, though not to the same darkness as is typical in the Chapada Diamantina. Shallow pools have accumulations of plant debris along the margin. Marginal vegetation is typical “Campo Rupestre”, an herbaceous-shrub vegetation type that develops at elevations of about 900 m on sandstones and quartzite. Shrubs of Bonnetia stricta (Nees) Nees, Mart. (Bonnetiaceae) dominate the margins along the stretches sampled. The only other fish species collected with C. elysium was Astyanax sp. The analysis of stomach contents of three specimens of C. elysium includes allochthonous and autochthonous items, composed mainly of aquatic insects (Trichoptera: larvae of Hydroptilidae and Hydropsychidae; Diptera: larvae of Simuliidae and Chironomidae; adult coleopterans; Plecoptera eggs), filamentous algae, and fragments of adult terrestrial insects (Hymenoptera: Formicidae), and numerous sand grains. Considering the pristine condition of the type locality and its location inside an official preservation area, there are no evident threats to the survival of C. elysium, despite its narrowly endemic distribution and probably small population size. Etymology. The specific epithet comes from the Greek elysium, in reference to the mythological Elysean Fields: a place or condition of ideal happiness; a state or place of perfect bliss. This alludes to the locality inhabited by the new species, a scenic pristine place (Fig. 7) shared with a single other fish species and no fish predators. A noun in apposition.

Neotrop. ichthyol. 16(2); DOI: 10.1590/1982-0224-20170146   RESUMO: Uma nova espécie do gênero Copionodon, subfamília Copionodontinae, é descrita para o trecho superior de um tributário do Rio Paraguaçu na Chapada Diamantina, Estado da Bahia, nordeste do Brasil. Este registro representa a ocorrência mais ao norte de Copionodontinae até agora conhecido. A nova espécie pode ser facilmente reconhecida por ter olho grande sem margem orbital livre. Outras características como o segundo hipo-branquial inteiramente cartilaginoso e uma faixa escura lateral irregular de largura uniforme também servem para diagnosticar o táxon. A combinação particular de caracteres do novo táxon é superficialmente intermediária entre Copionodon e Glaphyropoma. Entretanto, uma análise mais detalhada indica que forma um grupo monofilético com Copionodon e portanto deve ser incluída neste gênero.

| 7:12a | [Herpetology • 2020] Micryletta dissimulans • A New Species of Micryletta (Anura: Microhylidae) from southern Thailand
Abstract We report on a new species, Micryletta dissimulans sp. nov., from the lowland forests of southern Thailand, which is described based on molecular and morphological evidence. The new species is characterized by a combination of the following characters: small body size (20.3–22.4 mm in males, 24.4–26.7 mm in females); slender body habitus; head longer than wide; snout rounded in dorsal and lateral view; eye length equal to snout length; tibiotarsal articulation reaching to tympanum; dorsal surface slightly granulated to shagreened; supratympanic fold indistinct, ventrally edged in black with large black spot behind eye; outer metatarsal tubercle absent; dorsum reddish-brown with merging irregular-shaped brown blotches edged in beige, no black spots on dorsum; body flanks brown with large black spots edged in whitish mottling, two large black blotches in axillary and inguinal areas on each side; lateral sides of head black, with white patches on lips absent, whitish mottling on tympanum and axillary region; ventral surface pinkish to bluish-gray, translucent, laterally with dark-brown marbled pattern, medially immaculate; throat in males dark-gray with sparse white mottling laterally; iris copper-orange. The new species is divergent from all other congeners in 16S rRNA gene sequences (5.0%–7.4%). To date, Micryletta dissimulans sp. nov. is only known from a single locality in Saba Yoi District, Songkhla Province, Thailand, at an elevation of 120 m a.s.l., but is also expected to occur in neighboring parts of Malaysia. We suggest Micryletta dissimulans sp. nov. be considered as a Data Deficient (DD) species following the IUCN’s Red List categories (IUCN Standards and Petitions Committee, 2019). Keywords: Thai-Malay Peninsula, Indochina, Kangar-Pattani line, Micryletta dissimulans sp. nov, Micryletta sumatrana, Micryletta steinegeri, Micryletta lineata, Biodiversity, Taxonomy, mtDNA    
 Micryletta dissimulans sp. nov. Diagnosis: The new species is assigned to the genus Micryletta Dubois, 1987 based on the following morphological attributes: body size small; vomerine teeth absent; tympanum small, rounded, externally visible; subarticular tubercles on fingers and toes very prominent; three well-developed metacarpal tubercles; distinct supernumerary palmar and metatarsal tubercles posterior to base of digits; first finger not reduced; and webbing on fingers and toes absent (Alhadi et al., 2019; Das et al., 2019; Dubois, 1987; ... Etymology: The specific epithet “dissimulans” is a Latin adjective in the nominative case, feminine gender, derived from the Latin verb “dissimulo” meaning “to hide” or “to conceal”, and is given in reference to the iconic “Frog Skin” camouflage pattern, resembling the characteristic mottled and disruptive dorsal pattern of the new species. The name is also given in reference to the new species being concealed for a long time until its recent discovery. We recommend “Camouflaged Paddy Frog” as the common English name and “Eung Jiew Lay Prang” (อึ่งจิ๋วลายพราง) as the common Thai name of the new species.

| 8:19a | [Botany • 2020] Meriania baumgratziana (Melastomataceae) • Taxonomic Notes in Meriania from the Brazilian Atlantic Forest, including A New Species, a resurrected one and a new synonym
Abstract We present a new species, a new synonym, the resurrection of a species that has been synonymized before, updates on the distribution of three species, and lectotypifications for two species of Meriania from the Brazilian Atlantic Forest. Meriania baumgratziana is a new species apparently restricted to montane areas in the western portion of the state of Rio de Janeiro. It can be recognized by the sessile to subsessile leaves, these lanceolate, elliptic lanceolate or oblong-lanceolate, with cordate to cordulate, amplexicaul bases (seldom narrowly round), the abaxial surface in young leaves with the union of the primary and the inner pair of secondary veins with a membrane forming pocket domatia, these with trichomes emerging from the inside, then in older leaves the membranes frequently enlarged, globular, these hypertrophied structures sometimes caducous, or easily removed by friction, and by the pendulous inflorescences with 4-merous flowers. Meriania paratyensis Chiavegatto & Baumgratz is synonymized under M. sanchezii R.Goldenb., which in turn is resurrected from what we understand as a mistaken synonymy under M. paniculata DC. We present a discussion and illustrations of leaves and fruits, in order to explain these changes and compare all these three species, plus a fourth similar species, M. glabra (DC.) Naudin. The distributions of Meriania calyptrata (Naudin) Triana and M. sanchezii are updated, the former with the inclusion of specimens collected in the western tip of the state of Rio de Janeiro (it was previously recorded only for eastern São Paulo), and the latter in the exactly opposite way, with new records from Rio de Janeiro added to the previously known specimens from São Paulo. Finally, lectotypes are designated for Meriania calyptrata and M. glabra (DC.) Naudin (this superseding a previous, unnecessary designation of a neotype).

| 8:28a | [Invertebrate • 2019] Ophiopsila xmasilluminans • Brittle Stars from A Submarine Cave of Christmas Island, northwestern Australia, with Description of A New Bioluminescent Species (Echinodermata: Ophiuroidea) and Notes on Its Behaviour
Abstract Three species of ophiuroids are reported from a shallow water submarine cave on Christmas Island in northwestern Australia, including a new bioluminescent species, Ophiopsila xmasilluminans, which is described herein on the basis of 15 specimens. This new species occurs on sandy bottoms in the cave with disc buried and arms extended above the substratum. This species possesses a disc entirely covered by thick skin with small and delicate embedded scales and granules; 3 oral papillae, basically flat, fan-shaped but sometimes innermost or middle papilla spiniform; diamond shaped oral shield with rounded edges, as long as wide; long and flat arm spine; inner tentacle scale narrow, flat and long, arms approximately 18 times the disc diameter. We describe bioluminescence and burying behaviour, which suggest adaptation to submarine cave environments. Also reported herein is a rarely encountered species, Ophiomora elegans, based on a single specimen. Ophiomora elegans was previously known only from southern Mozambique, the east coast of Africa and the Ryukyu Islands. We also include a new record of Ophioconis claviculata, which was previously known only from the Ryukyu Islands. Key words: brittle star, endemism, new species, submarine cave, bioluminescence, Christmas Island
   Ophiopsila xmasilluminans new species Diagnosis. Disc surface entirely covered by thick skin with embedded small and delicate scales and granules; 3 oral papillae, basically as scales, but sometimes spiniform for one on innermost or middle position; diamond-shaped oral shield with rounded edges, as long as wide; long and flat arm spines, 6 in maximum number; inner tentacle scale narrow, flat and long; arms approximately 18 times longer than disc diameter. Etymology. The specific name is an adjective in apposition formed as a compound of the island name “xmas” and the Latin participle, illuminans, meaning “lighting”, referring to its sampling locality name (Christmas Island) and luminescence. Common Japanese name. Dohkutsu-hikari-kumohitode. Distribution. Known only from the type locality, a submarine cave called as “Thunderdome Cave”, northern coast of Christmas Island, northwestern Australia, approximately 10 m depth (type locality, Fig. 1). Tan et al (2014) noted that Ophiopsila pantherina [= this new species] was also found at “Thundercliff Cave”, which is located near Thunderdome Cave. However, specimens of this species were only collected from Thunderdome Cave by the last author (Yoshihisa Fujita). Habitat. All type specimens of Ophiopsila xmasilluminans new species were collected in sandy bottoms in the submarine cave, with buried disc and arms extended into the water (Fig. 2B).

| 9:48a | [PaleoOrnithology • 2024] Ardenna buchananbrowni • A New Diving Pliocene Ardenna Shearwater (Procellariiformes: Procellariidae) from New Zealand
Abstract We report a new species of shearwater, Ardenna buchananbrowni sp. nov., from the Pliocene of New Zealand. It is both the smallest and oldest known diving member of the genus, demonstrating that this now abundant form of shearwater has had a long presence in southern oceans. Ardenna buchananbrowni sp. nov. is among the few extinct shearwaters described from the Southern Hemisphere and adds to an increasingly diverse seabird assemblage in the Pliocene of the region. Keywords: biogeography; fossil; Piacenzian; Procellariiformes; Tangahoe Formation; Taranaki; Waipipian   Systematic Palaeontology Order Procellariiformes Fürbringer, 1888 The present fossils belong to Procellariiformes because of their straight, deeply grooved beaks, prominent dorsally opening nostrils, enlarged nasal glands above the eyes, and long, narrow wing bones. Family Procellariidae Leach, 1820 The present fossils belong to Procellariidae because of their intermediate size (Diomedeidae are larger, Oceanitidae and Hydrobatidae smaller), gracile beaks, and dorsally projecting nostrils. Genus Ardenna Reichenbach, 1853 Type species: Procellaria gravis O’Reilly, 1818. Ardenna buchananbrowni sp. nov. Alan J. D. Tennyson, Rodrigo B. Salvador, Barbara M. Tomotani and Felix G. Marx. 2024.
