| 3:52a | [Entomology • 2024] Heleocoris stephanus • A New Species of Creeping Water Bug (Heteroptera: Naucoridae: Laccocorinae) from Kallada River, Kerala, India
Abstract A new species of Heleocoris, Stål (1876) was collected from the upstream Kallada River in Kerala, southwestern India. This discovery brings the number of described species for this genus in India to twelve. This species can be diagnosed by the overall body coloration and distinct morphological & genital features. Descriptions including a habitus photograph, ecology, and diagnostic comparisons among congeners are provided. Keywords: Coloration, congeners, genitalia, morphology, upstream, Urukunnu
Heleocoris stephanus sp. nov. Diagnosis: Heleocoris stephanus sp. nov. is similar to the congener H. vicinus (Montandon, 1910), by size, and overall coloration. However, H. stephanus is notably different from H. vicinus by the finely granulose, dark brown scutellum with irregular yellow apex and thick median longitudinal yellowish patch. H. majusculus (Montandon, 1908) and H. rotundatus (Montandon, 1908) are other congeners reported from the neighbouring state of Tamil Nadu. The former drastically differs from H. stephanus by its entirely black scutellum and overall body size, while the latter differs from H. stephanus by its black coloured body beneath with greyish pilose and body size. H. breviceps (Montandon, 1897) is another congener reported from the Indian states such as Andhra Pradesh, Himachal Pradesh, Maharashtra, and Tamil Nadu. This congener differs from H. stephanus by largely blackish abdomen beneath and brownish scutellum. As the name implies, H. elongatus (Montandon, 1897) differs from H. stephanus by its body ... Etymology: This specific epithet “stephanus” refers to the Institution where this significant research was conducted at the Zoology Research Centre, St. Stephen’s College, Pathanapuram. St. Stephen’s College was founded in 1964 after the name of St. Stephen, one of the first seven ordained Deacons and the first Martyr of Christianity. Dani Benchamin, R. Sreejai and M.S. Arya. 2024.

| 8:46a | [Botany • 2024] Duguetia rolimii (Annonaceae: Duguetieae) • A New large tree Species from the Atlantic Forest of Espírito Santo, Brazil
Abstract A new species of Duguetia from Reserva Natural Vale, in the Atlantic Forest of the Brazilian state of Espírito Santo, is described and illustrated, and an updated key to the Duguetia species from this state is presented. Duguetia rolimii is known only from two large trees, restricted to the municipality of Linhares. It resembles D. sooretamae in having young twigs densely covered with stellate scales, narrow and shiny leaves with similar dimensions, and fruits with more than 200 fertile monocarps. Nevertheless, these two species can be distinguished from each other mainly by the type of vegetation where they occur, plant size, the density of stellate scales at the lower side of the leaves, the angle between the primary and secondary leaf veins, the shape of the flower buds, length of the upper bract, the shape of the fertile monocarps and indument of the areoles. Comments on distribution, conservation status and field photos of the new species, and comparisons with other related species are provided. Keywords: Annonoideae; Duguetieae; Espírito Santo; Neotropical flora; Tabuleiro forest; taxonomy.
Duguetia rolimii M.L.Bazante, G.S.Siqueira & Maas, sp. nov. Duguetia rolimii is most similar to D. sooretamae, but D. sooretamae has leaves totally to densely covered with stellate scales 0.3-0.5 mm in diam. below, secondary veins at an angle more than 70° with the primary vein and indistinct at the lower side of the leaves, cauliflory present, upper bract ca. 1 mm long, flower buds broadly to very broadly ovoid with three slightly to absent ridges and an obtuse and not apiculate apex, petals broadly ovate with more than 12 mm wide, stamens 3-4 mm long with apex of connective not umbonate, fruit with fertile monocarps ovoid and with areoles narrowly pyramidal, totally covered with persistent stellate scales, whereas D. rolimii has leaves rather densely to sparsely covered with stellate scales 0.1-0.2 mm in diam. below, secondary veins at an angle up to 65° with the primary vein and distinct at the lower side of the leaves, cauliflory absent, upper bract 6-8 mm long, flower buds triangular-ovoid with three prominent ridges and an acute and apiculate apex, petals narrowly panduriform-elliptic to narrowly elliptic up to 12 mm wide, stamens up to 1.5 mm long with apex of connective umbonate, fruit with fertile monocarps obtrulloid to oblongoid and with areoles shallowly ovoid-pyramidal, glabrous or sparsely covered with stellate hairs towards the apicule (Fig. 3). Etymology: The specific epithet honors the Brazilian researcher Dr. Samir G. Rolim, in recognition of his significant contributions to the biological knowledge of the Atlantic Forest, particularly of the Reserva Natural Vale. In 2016, Rolim and collaborators coordinated the remarkable book “Floresta Atlântica de Tabuleiro: diversidade e endemismos na Reserva Natural Vale”, which highlights the biodiversity and relevant research conducted in this protected area.

| 9:50a | [Ichthyology • 2024] Enteromius niggie • Naming the other Cousin: A New Goldie Barb (Cyprinidae: Smiliogastrininae) from the northeast escarpment in South Africa, with proposed taxonomic rearrangement of the goldie barb group in southern Africa
Abstract A growing body of evidence indicates that the global diversity of freshwater fishes has not been fully documented. Studies of freshwater fishes that were previously thought to be morphologically variable have revealed the existence of deeply divergent lineages, with many distinct species. In southern Africa a number of Enteromius species exhibit either exceedingly wide or divided distribution patterns that should be rare for freshwater fishes with limited dispersal opportunities between river systems. One such species is the sidespot barb, Enteromius neefi. As currently defined, E. neefi has a disjunct distribution that is divided between rivers in the northeast escarpment in South Africa and Eswatini, and tributaries of the Upper Zambezi in Zambia and southern Congo in the Democratic Republic of Congo, with a large geographic gap between these two populations. With the use of molecular and morphological methods, the level of divergence between the two populations was examined, and a new species was described from the Steelpoort River in the Limpopo River system of South Africa. Findings from this study provide further evidence for a number of taxonomic problems within the goldie barbs of southern Africa, and some taxonomic rearrangements are proposed for this group. Keywords: color pattern, Cypriniformes, integrative taxonomy, systematics
Enteromius niggie sp. nov. [niggie: ‘nᶕᶍi] (g/ch from Afrikaans/Dutch) is pronounced with a hard guttural sound, made at the back of the throat. Proposed common names: Southern sidespot barb; Suidelike sykol ghieliemientjie (Afrikaans). Diagnosis: E. niggie sp. nov. belongs to the goldie barb group in southern Africa, which is characterized by species with a soft primary dorsal-fin ray, a relatively short compact body (<70 mm SL), the presence of two pairs of well-developed barbels, 24–30 lateral line scales, and a bright golden breeding colouration in males. Along with E. niggie the goldie barb group includes the species E. pallidus (Smith 1841), E. brevipinnis (Jubb 1966), E. neefi s.s. (Greenwood, 1962), E. thamalakanensis (Fowler 1935), E. greenwoodi (Poll, 1967), E. lineomaculatus “Malawi” (Boulenger 1903), and E. viviparus (Weber 1897). E. niggie and E. neefi can be readily distinguished from all the aforementioned species by the presence of distinctive pigmentation along the margins of flank scales that are expressed as wavy parallel lines (Figure 4a,b). Further, E. niggie can be distinguished from E. neefi by the lack of wavy parallel lines below the lateral line (Figure 4c) and by the lack of dark bold and rounded spots on the dorsal midline of the body (Figure 4d). Etymology: When describing the species E. neefi, Greenwood (1962) used the Afrikaans word neef, which means “male cousin,” a humorous acknowledgment to Graham Bell-Cross (1927–1998) who collected the types of E. neefi and often called Greenwood by the Afrikaans word oom which means “uncle” (Paul Skelton, personal communication). Therefore, in keeping with Afrikaans familial terms, the use of nig [‘nᶕᶍ] to name the new species, which means “female cousin,” is a symbolic representation of the historical association between these two species, which were considered to represent disjunct populations of the same species.

| 3:06p | [Crustacea • 2024] Valettietta synchlys & V. trottarum • Biogeography and Phylogeny of the scavenging amphipod Genus Valettietta (Amphipoda: Alicelloidea), with Descriptions of Two New Species from the Abyssal Pacific Ocean
Abstract Valettietta Lincoln & Thurston, 1983 (Amphipoda: Alicelloidea) is an infrequently sampled genus of scavenging amphipod, with a known bathymetric range from 17–5467 m encompassing a variety of habitats from anchialine caves to abyssal plains. Molecular systematics studies have uncovered cryptic speciation in specimens collected from the abyssal Pacific, highlighting uncertainty in the description of Valettietta anacantha (Birstein & Vinogradov, 1963). Here, we apply an integrative taxonomic approach and describe two new species, Valettietta trottarum sp. nov. and Valettietta synchlys sp. nov., collected at abyssal depths in the Clarion-Clipperton Zone, Pacific Ocean. Both species can be distinguished by characters of the gnathopods, uropod 3, and the inner plate of the maxilliped. Further, molecular phylogenetic analyses of two mitochondrial (16S rDNA and COI) and two nuclear (Histone 3 and 28S rRNA) regions found both new species to form well-supported clades and allowed us to re-identify previously published records based on genetic species delimitation. The biogeography of Valettietta is discussed in light of these re-evaluated records, and a new taxonomic key to the genus is provided. These new taxa highlight the strength of applying an integrated taxonomic approach to uncover biodiversity, which is critical in regions being explored for potential industrial purposes. cryptic species, integrative taxonomy, DNA barcoding, Clarion-Clipperton Zone, deep-sea mining, biodiversity  Valettietta synchlys sp. nov. Etymology: Synchlys, Greek, meaning mixed or ‘washed together by the waves’, alluding to the morphological characters of this species resembling a mixture of both Valettietta anacantha and Valettietta gracilis. Used as a noun in apposition. Valettietta trottarum sp. nov. Etymology: This species is named for the Trott family of Deal, Kent (UK). In their service as sailors of luggers, they saved many lives before the introduction of formal lifeboats (c.1750—c.1856). It is particularly named for Robert and Suzanne Trott, who spent their childhood in the city of Valetta, Malta. Used as a noun in apposition, gender feminine. Eva C. D.

| 3:09p | [Herpetology • 2024] Cyrtodactylus laevis • A New Species of Cyrtodactylus tibetanus Group (Squamata: Gekkonidae) from Xizang Autonomous Region, China
Abstract A new Cyrtodactylus species, C. laevis sp. nov., from the dry-hot valleys near the Yarlung Zangbo River in Re Village, Jindong Countryside, Lang County, Linzhi City, Xizang Autonomous Region, China, is described herein based upon the integrative taxonomic results combining molecular phylogenetic systematics and morphological characteristic comparisons. Our molecular phylogeny was inferred by combining three mitochondrial gene fragments (16S/CO1/ND2), and it indicated a distinct differentiation between the new species and C. tibetanus species complex, with obvious genetic distances (16S 9.9–11.8%/CO1 16.5–18.2%/ND2 16.6–18.5%) detected, supporting its validity. Morphologically, the new species can be easily distinguished from its congers by the following characters: (1) medium size (SVL 48.58–50.92 mm), (2) tubercles on dorsum sparse, (3) tail segments absent and tubercles on tails absent, (4) supralabials 10–12 and infralabials 8–10, (5) interorbital scales between anterior corners of the eyes 28–32, (6) scale rows at midbody 96–98, (7) ventral scales between mental and cloacal slit 145–153, (8) ventral scale rows 41–45, and (9) 4 to 5 white–yellow transverse bands with brown dots and black merges between the nape and sacrum. The description of C. laevis sp. nov. increased the total species number of C. tibetanus group to three, and the total Cyrtodactylus species number in Xizang to six and in China to eleven. The new species is currently only known from the type locality with its extremely small populations and needs future surveys to reveal its distribution range, population status, natural history, and mechanisms so that the new species can coexist with Altiphylax medogense.

Cyrtodactylus laevis sp. nov. Ma, Wang and Jiang, 2024 Diagnosis. (1) Medium size (SVL 48.58–50.92 mm); (2) tubercles on dorsum are sparse; (3) tail segments are absent and tubercles on tails are absent; (4) supralabials 10–12 and infralabials 8–10; (5) interorbital scales between anterior corners of the eyes 28–32; (6) scale rows at midbody 96–98; (7) ventral scales between mental and cloacal slit 145–153; (8) ventral scale rows 41–45; (9) four to five white–yellow transverse bands with brown dots and black merges between the nape and sacrum.
Etymology. This specific epithet refers to its tubercles-sparse skin surface. We suggest “Smooth Bent-Toed Geckos” as its English common name and “光滑裸趾虎” (Guāng Huá Luŏ Zhĭ Hŭ) as its Chinese common name. Distribution and habitats. This new species is only known to be distributed in Re Village, Jindong Countryside, Lang County, Linzhi City, Xizang Autonomous Region, China. The elevation is 3065 m a.s.l. We found the specimens under a rock in the dry-hot valleys near the Yarlung Zangbo River on a sunny afternoon (AT 26 °C, RH 42%; Figure 6), so we consider that it is a nocturnal species. Moreover, Altiphylax medogense (Zhao and Li, 1987) and Laudakia sacra (Smith, 1935) were also found inhabiting the same area.
Simple Summary: More than 350 species (32 species groups) of Cyrtodactylus Gray, 1827, are reported currently, with a wide distribution from Himalaya, South Asia, Southeast Asia, to Melanesia. Cyrtodactylus tibetanus group, as the earliest Cyrtodactylus diverging clade, are endemic to the Yarlung–Tsangpo River Basin of Tibetan Plateau, only containing two species: C. tibetanus and C. zhaoermii. However, two newly collected Cyrtodactylus specimens from the eastern region of Lang County, Linzhi City, Xizang Autonomous Region, China, were found to be an unnamed taxon of this group based upon the molecular phylogeny, which was conducted using a concatenation data matrix (the partial 16S ribosomal RNA gene (16S), the partial cytochrome c oxidase subunit 1 gene (CO1), and the partial NADH dehydrogenase subunit 2 gene (ND2)) and morphological comparisons, as the new species could be easily identified from other C. tibetanus group species through the absence of the tubercles on dorsum, tail segments, and the tubercles on tails. The new species is currently only known from the type locality with its extremely small populations, with great demand for future investigations to figure out its distribution range, population status, natural history, and mechanisms so that this new species can coexist with Altiphylax medogense.

Abstract Key words. Cao Bang Province, cryptic species, Theloderma woltersi, new species, molecular phylogeny, taxonomy
Family Rhacophoridae Hoffman, 1932 Genus Theloderma Tschudi, 1838 Theloderma woltersi, new species Diagnosis. Morphologically, the new species from Cao Bang Province can be assigned to the genus Theloderma by a combination of the following characteristics: Small in size (SVL 25.1–26.2 mm in males, 30.3 mm in female), distinct tympanum, round canthus rostralis, bony ridges from canthus rostralis to occiput lacking, and skin of head not co-ossified to the skull, tip of finger dilated into disc (see Liem, 1970; McLeod & Ahmad, 2007; Rowley et al., 2011; Hou et al., 2017). However, because morphological synapomorphies are lacking for the genus Theloderma, and thus its monophyly is not certain (Bain et al., 2009; Li et al., 2009; Rowley et al., 2011) we additionally used molecular evidence to provide independent support for the species’ distinctiveness and its phylogenetic placement within Theloderma. ...
Etymology. We dedicate the species name to the late Jürgen Wolters, founding member of Stiftung Artenschutz, which supports current conservation-based mossy frog research in Vietnam. Furthermore, Stiftung Artenschutz has been dedicated to supporting amphibian research through its specialised amphibian program for over 15 years.

Abstract A new freshwater species with two new subspecies of the gobiid fish genus Rhinogobius is described from the Yaeyama Group of the Ryukyu Islands, Japan. One of the subspecies, Rhinogobius aonumai aonumai (29 specimens, 35.9–70.5 mm SL) known only from Iriomote-jima Island, is distinguished from all congeneric species-group taxa (species and subspecies) by having the following combination of features: 9–15 predorsal scales; 32–37 longitudinal scales; 11+15–17=26–28 vertebrae (mode 27); anteriormost two pterygiophores (proximal radials) of the second dorsal fin mounted over the neural spine of 10th vertebra; fifth segmented pelvic-fin ray divided into 3–4 (usually four) branches at the position where proximal-most segment of each branch alignes transversely; yellow-colored body in freshly-collected; no dark spot on first dorsal fin; caudal fin with vertical rows of dark spots or forming dark zigzag bands. The other subspecies, Rhinogobius aonumai ishigakiensis (12 specimens, 33.3–56.5 mm SL) known only from Ishigaki-jima Island, is distinguished from all congeneric species-group taxa by having the following combination of features: 10–14 predorsal scales; 33–38 longitudinal scales; 10+16–18=26–28 vertebrae (mode 27); anteriormost two pterygiophores (proximal radials) of the second dorsal fin mounted over the neural spine of 9th vertebra; fifth segmented pelvicfin ray divided into 2–3 (usually two) branches at the position where the proximal-most segment of each branch alignes transversely; yellow-colored body in freshly-collected; no dark spot on first dorsal fin; caudal fin with dark zigzag bands on the caudal fin.

| 3:26p | [Botany • 2024] Ceiba guarani (Malvaceae: Bombacoideae) • A New Species from sub-Andean southern Bolivia and the Sierras of northwestern Argentina
Abstract Based on observations made during botanical surveys in the southern sub-Andean of Bolivia, analysis of collected material, review of herbarium material and online databases, we determined that the Ceiba populations of the xeric Bolivian-Tucuman forests, previously identified as Ceiba chodatii, correspond to a new species. Given that the morphological, ecological and distributional characteristics differ from those observed in populations of C. chodatii, we propose Ceiba guarani sp. nov. Our field observations and distribution data from the revised specimens indicate that C. chodatii is naturally restricted to the Chaco plains and a strip of the southern Subandean foothills, whereas Ceiba guarani is distributed mainly in the Subandean ranges.

Abstract Sonerila dongii, a new species from Lam Dong province in South Vietnam, is described and illustrated here. The morphological characteristics of this new species distinguish it from any previously documented species in the Indochina region because it lacks a tuber and likely adapts to periodic drought seasons by utilizing its fleshy stems. Sonerila dongii bears a resemblance to S. peninsularis with its variegated, ovate foliage, and stem and inflorescence covered with minutely brown glandular trichomes. However, the new species differs from S. peninsularis in lacking an underground tuber (vs. tuber present), stem terete (vs. quadrangular) and branched (vs. usually unbranched), petals glabrous (vs. abaxial surface with long stipitate glandular trichomes) and longer anthers 4.5–5 mm long (vs. 1.5–2.5 mm). The conservation status of Sonerila dongii is assessed as data deficient (DD), according to the IUCN Red List Categories and Criteria. biodiversity, endemism, Flora of Vietnam, plant diversity, plant taxonomy, Eudicots  Sonerila dongii Danh Duc Nguyen, Van Canh Nguyen, Che Wei Lin. 2024.
