| 3:30a | [Botany • 2021] Phloeophila condorana • A Taxonomic Revision of Genus Phloeophila (Orchidaceae: Pleurothallidinae) in Ecuador
ABSTRACT The orchid genus Phloeophila is distributed from southern Mexico to Brazil and Bolivia, as well as Cuba. A taxonomic revision including the three Phloeophila species present in Ecuador is presented. Morphological characteristics, an identification key, maps of known localities and illustrations of the species are also included. In Ecuador, species of Phloeophila are only known from the Amazonian rainforests, growing from 890 to 1600 meters of altitude. Phloeophila condorana is described as a new species based on specimens collected in the Ecuadorian province of Zamora-Chinchipe and compared to Phloeophila nummularia. Phloeophila nummularia is reported for the first time in Peru. A lectotype for Pleurothallis echinantha is selected. KEYWORDS: Amazon, new species, orchid, rainforests, taxonomy
Phloeophila condorana M.M. Jiménez & Vélez-Abarca sp. nov. Diagnosis: This species is similar to P. nummularia from which it differs by its 1 mm long peduncle (vs 8 mm), the sepals yellow and red colored with cinnamon brown stripes (vs whitish gray and yellow sepals with reddish purple stripes), slightly spiculate on the outside (vs sparsely pubescent), the synsepal slightly concave below the middle (vs connate into a broad tube), the inner integument glandular (vs finely pubescent), the petals triangular-ovate with yellow veins (vs oblong with brown stripes), the lip verrucose-glandular adaxially (vs pubescent-verrucose adaxially) and the column yellow, lobed and dentate at the apex (vs yellowish brown with stripes, erose and cucullate at the apex). Etymology. The specific name refers to the Cordillera del Cóndor, an important mountain range in southern Ecuador renowned for its high biological diversity.

| 3:45a | [Botany • 2024] Ophiorrhiza reflexa (Rubiaceae) • A New Species from A Karst Region in Guangxi, China
Abstract Ophiorrhiza reflexa, a new species from Guangxi, China, is described and illustrated in this study. It is morphologically similar to O. alatiflora due to the branched inflorescence, distylous flowers and the tubular-funnelform corolla with five longitudinal wings. The new species can be distinguished from O. alatiflora by its erect inflorescence, its smaller and equal-sized calyx lobes 0.5–0.7 mm long, its corolla tubes winged to the middle and the wings straight and its strongly reflexed corolla lobes at anthesis. Ophiorrhiza reflexa is assessed as least concern (LC) according to IUCN Categories and Criteria. Key words: China, new taxon, Ophiorrhiza, Rubiaceae, taxonomy
Ophiorrhiza reflexa L.Wu & Q.R.Liu, sp nov. Diagnosis: The new species is most similar to O. alatiflora, but can be distinguished from the latter by the inflorescences which are erect from the earliest developmental stages (vs. drooping when young, then erect), the small and equally-sized calyx lobes 0.5–0.7 mm long (vs. 0.9–1.8, sometimes to 2.5 mm long and usually unequal), the longitudinal wings on the corolla tube which run to the middle of the tube and are straight (vs. wings running along entire length and obviously undulate) and the strongly reflexed corolla lobes (vs. spreading) at anthesis. Etymology: The species epithet refers to the reflexed corolla lobes. The Chinese name is given as ‘fan-ban-she-gen-cao (反瓣蛇根草)’.

| 6:59a | [Herpetology • 2024] Leptobrachella guinanensis • A New Species of the Genus Leptobrachella Smith 1925 (Anura: Megophryidae) from Shiwandashan National Nature Reserve, Guangxi, China
Abstract A new species of the genus Leptobrachella, L. guinanensis sp. nov., is described in this study based on morphological, molecular, and bioacoustic data. The species was discovered in the Shiwandashan National Nature Reserve in Shangsi County, Guangxi, China. Phylogenetically, L. guinanensis sp. nov. is closely related to L. ventripunctata. However, there are distinct morphological differences betweenisp. nov. and L. ventripunctata, as well as three other sympatric species (L. shangsiensis, L. shiwandashanensis, and L. sungi). These differences include body size (SVL 30.5–32.5 mm in males; 38.7–41.8 mm in females in the new species vs 25.5–28.0 mm in males, 31.5–35.0 mm in females in L. ventripunctata), the absence of brown spots on the ventral surface (vs chest and belly creamy white with many scattered brown spots in L. ventripunctata), 1/3 toe webbing and wide toe lateral fringes (vs no toe webbing and no lateral fringes in L. ventripunctata), and distinct dermal ridges under toes (vs absent in L. ventripunctata). Furthermore, the dominant vocal frequencies of the new species range from 7.3 to 8.3 kHz, which is unique compared to other Leptobrachella species and represents the highest dominant frequencies ever recorded. The Shiwandashan National Nature Reserve is now home to four known sympatric species of Leptobrachella. Key words: Bioacoustics, morphology, phylogeny, sympatric species
Leptobrachella guinanensis Chen, Li, Peng & Liu, sp. nov. Diagnosis: Leptobrachella guinanensis sp. nov. can be distinguished from its congeners by a combination of the following characters: (1) SVL 30.5–32.5 mm in males; 38.7–41.8 mm in females; (2) 1/3 toe webbing, wide lateral fringes; (3) dorsal surface shagreened with small, raised tubercles and longitudinal ridges; (4) ventral surface creamy white without dark brown spots; (5) throat immaculate creamy white and its margin concentrated brown spots; (6) iris bicoloured, upper half light copper, transitioning to silver in lower half; (7) crossbars of hindlimbs with tubercles; (8) distinct dermal ridges under the toes; (9) a pair of glands under the vent; (10) tibia-tarsal articulation reaching to centre of eye; (11) relatively higher dominant frequency of advertisement calls (7.3–8.3 kHz).
Etymology: The species name guinanensis is derived from the geographic distribution of this species, specifically the southern Guangxi region. The suggested English name for this species is Gui Nan Leaf Litter Toad, while the Chinese name is Gui Nan Zhang Tu Chan (桂南掌突蟾).

| 8:21a | [Diplopoda • 2024] Glyphiulus pseudocostulifer, G. steineri & G. houaphanhensis • Integrated Taxonomy of Three New Species of Glyphiulus Gervais, 1847 (Spirostreptida: Cambalopsidae) from Laos
Abstract Three new species of the millipede genus Glyphiulus Gervais, 1847 are described and illustrated based on specimens collected from caves in Laos, namely G. pseudocostulifer, new species, from Oudomxay Province, G. steineri, new species, from Khammouan Province, and G. houaphanhensis, new species, from Houaphan Province. All of them belong to the javanicus-group, which share the unique structure of the first pair of legs in males and the carinotaxic formula of midbody rings. However, they differ from each other in the number of ommatidia, body colouration, the carinotaxic formula of the collum, as well as anterior and posterior gonopod structures. Mitochondrial COI sequences were used as DNA barcodes for species delineation, and were successfully obtained for two of the new species (G. pseudocostulifer, new species, and G. steineri, new species). Phylogenetic analyses revealed strong support for all examined Glyphiulus species, even for a pair of species which exhibited high morphological similarity, with mean uncorrected COI p-distances between Glyphiulus species ranging from 15–22%. Two additional Glyphiulus species are listed, but not described, as male material is lacking. One of them occurs in direct sympatry with G. houaphanhensis, new species. An identification key to the species of Glyphiulus so far recorded from Laos and a distribution map are also presented. Key words. millipedes, key to species, cave fauna, molecular systematics, COI
Glyphiulus pseudocostulifer, new species Etymology. To emphasise the obvious similarities to G. costulifer Golovatch, Geoffroy, Mauriès & VandenSpiegel, 2007. Noun in apposition. Glyphiulus steineri, new species Etymology. To honour the German collector and biospeleologist Helmut Steiner, an active explorer of the caves of Laos, noun.

| 4:21p | [Entomology • 2024] Hylaeus chuukensis, H. aureaviridis, H. derectus, H. navai, etc. • Canopy Specialist Hylaeus Bees (Hymenoptera: Colletidae) highlight Sampling Biases and resolve Michener’s Mystery
Large parts of the Pacific were thought to host low bee diversity. In Fiji alone, our recent estimates of native bee diversity have rapidly increased by a factor of five (from 4 to >22). Here, we show how including sampling of the forest canopy has quickly uncovered a new radiation of Hylaeus (Hymenoptera: Colletidae) bees in Fiji. We also show that Hylaeus are more common across the Pacific than previously thought and solve one of Charles Michener’s mysteries by linking the previously enigmatic French Polynesian Hylaeus tuamotuensis to relatives in Fiji. We use systematic techniques to describe eight new Hylaeus species in Fiji (n = 6), French Polynesia (n = 1), and Micronesia (n = 1), and discuss impressive dispersal events by this genus. These clades also double the number of Hylaeus dispersals out of Australia from two to four. Our discovery highlights the severe impact of bee sampling methods on ecological interpretations and species discovery, specifically that canopy sampling is needed to correctly assess forest bee diversity even where there is a very long record of sampling. It further highlights the potential for forests to host higher-than-anticipated diversity and conservation value. This has broad methodological and regulatory impacts for land managers seeking to make choices about pollination services and diversity. The new species are Hylaeus (Euprosopoides) chuukensis Dorey, Davies, and Parslow; H. (Prosopisteron) albaeus Dorey, Davies, and Parslow; H. (P.) apertus Dorey, Davies, and Parslow; H. (P.) aureaviridis Dorey, Magnacca, and Parslow; H. (P.) breviflavus Magnacca; H. (P.) derectus Dorey, Davies, and Parslow; H. (P.) navai Dorey, Davies, and Parslow; and H. (P.) veli Dorey, Davies, and Parslow.   James B. Dorey, Olivia K. Davies, Karl N. Magnacca, Michael P. Schwarz, Amy-Marie Gilpin, Thibault Ramage, Marika Tuiwawa, Scott V. C. Groom, Mark I.
