| 8:19a | [Botany • 2024] Gastrodia lohitensis (Orchidaceae: Epidendroideae: Gastrodieae) • A New mycotrophic Orchid from India
Abstract A new mycotrophic species of the genus Gastrodia (Orchidaceae), is described and illustrated from Arunachal Pradesh, India. The species is unique within the genus in having two oblong–linear calli which are parallelly arranged along the margins of the claw of the labellum, and white flowers. The new species is assessed as 'Endangered' according to the IUCN red list criteria.

| 8:54a | [Mammalogy • 2024] Typhlomys taxuansis • A New Species of the Genus Typhlomys (Rodentia: Platacanthomyidae) from Vietnam
Abstract Background: The paper presents novel findings of little-known species of rodents, the blind tree mice Typhlomys in Son La Province, Vietnam, with the first morphological and genetic characterisation and taxonomical description of the new species, T. taxuansis. The study also summarises all the data available on this genus species distribution, museum collections and notes on its taxonomy, which are important to establish the proper conservation status of the species. An exhaustive map of the findings is provided, along with a refined taxonomic key for all six currently morphologically characterised species of the genus. It is shown that, based on the data available to date, the genus is still far from complete. Most species, apparently, do not need a special conservation measure; their status may be established as Least Concerns and Near Threatened (B1a+2a) and the current population trend is stable (IUCN). New information: The paper introduced innovative findings regarding lesser-known rodents, the blind tree mice Typhlomys in Son La Province, Vietnam, along with the primary morphological and genetic identification and taxonomic explanation of the novel species T. taxuansis. Keywords: Southeast Asia, Vietnam, rodents, taxonomy, biodiversity
Typhlomys taxuansis sp. nov. Diagnosis: The new species, morphologically, is most similar to T. daloushanensis, but can be distinguished, based on its dental and skull morphology. Based on genetic diversity, the most relative genetic lineage is T. fengjiensis. It obviously differs from geographically most adjacent species T. chapensis and T. nanus by a more flattened braincase; from all known Typhlomys species, except for T. cinereus, by zygomatic arch with deeper incurve; from T. cinereus by mesofossette on M1 open on both buccal and lingual sides rather than open on the buccal side only; and from T. nanus by posterofossettid on M1 present. The new species further differs from other species, except T. daloushanensis, by anterofossette on M2 present. Etymology: The specific Latin name taxuansis composed as an adjective refers to its type locality in Ta Xua Nature Reserve, Son La Province, Bac Yen District, Vietnam. Due to the sampling location being the southernmost location currently known for this genus, we suggest “southern blind tree mouse” as the English common name. Alexander E.

| 2:43p | [Mammalogy • 2024] Murina yushuensis • A New Dpecies of Tube-nosed Bat (Chiroptera: Vespertilionidae: Murina) from Qinghai–Tibet Plateau, China
Abstract In 2018, an adult male of a small-sized Tube-nosed Bat (Chiroptera: Vespertilionidae: Murina) was captured at an arid cave located on the Qinghai–Tibet Plateau in Yushu City, Qinghai Province, China. Despite external morphological similarities with those of M. harpioloides and M. chrysochaetes, the individual in question displays explicit craniodental differences that distinguish it from either species. Morphological and morphometric evidence, coupled with phylogenetic analyses utilizing the mitochondrial COI gene, confirmed that it represents a distinct and still unknown species of Murina, described herewith as M. yushuensis sp. nov. Our research highlights the importance of future surveys aimed at exploring cryptic species diversity in the Qinghai–Tibet Plateau and adjacent under-surveyed regions. morphometrics, Murininae, phylogeny, systematics, taxonomy

| 2:48p | [Botany • 2024] Drymonia quadrangulata • Resolving the Drymonia killipii Complex (Gesneriaceae) results in A New Species from the northwestern Andes of South America
Abstract A new species, Drymonia quadrangulata Clavijo & J.L.Clark, sp. nov. (Gesneriaceae, Columneinae), is described from the western Andean slopes of southern Colombia and northern Ecuador. The new species has been historically confused with D. killipii, an endemic species to Colombia, restricted to the lowlands of the Chocó biogeographic region in the departments of Cauca, Chocó, and Valle del Cauca. These two species have large foliaceous calyx lobes that cover at least half of the corolla tube, and tubular-infundibuliform corollas. The new species differs by strigose quadrangulate and sometimes winged stems, leaves reticulate abaxially with obtuse to subcordate bases, midveins green, corolla lobes white to yellow with margins incised to short laciniate, and indehiscent berry fruits. Digital photographs, detailed morphological comparisons with the similar species, and an IUCN preliminary risk extinction assessment are provided for the new species. Key words: Andes, Chocó biogeographic region, Colombia, Columneinae, Ecuador
Drymonia quadrangulata Clavijo & J.L.Clark, sp. nov. Diagnosis: Differs from Drymonia killipii by quadrangular to strongly angulate stems in cross-sections vs. terete; stems strigose apically vs. hirsute; blades 12.0–26.7 cm long vs. 20.5–45.0 cm long; corolla lobes white to yellow vs. royal purple to maroon; and fruits indehiscent globose berries vs. bivalved fleshy capsules. Etymology: The specific epithet is in reference to the quadrangular to strongly angulate stem cross-section which is occasionally winged (Figs 2E, 3). Laura Clavijo and John L. Clark. 2024. Resolving the Drymonia killipii (Gesneriaceae) Complex results in A New Species from the northwestern Andes of South America. PhytoKeys. 248: 207-222. DOI: doi.org/10.3897/phytokeys.248.123248  Resumen: Se describe una nueva especie, Drymonia quadrangulata Clavijo & J.L.Clark, sp. nov. (Gesneriaceae, Columneinae), de la vertiente occidental de los Andes del sur de Colombia y el norte de Ecuador. La nueva especie ha sido históricamente confundida con D. killipii, una especie endémica de Colombia, restringida a las tierras bajas del Chocó biogeográfico en los departamentos de Cauca, Chocó y Valle del Cauca. Estas dos especies tienen un cáliz foliáceo que cubre al menos la mitad del tubo de la corola y corolas tubulares-infundibuliformes. La nueva especie se distingue por sus tallos estrigosos, cuadrangulares y a veces alados, hojas reticuladas en el envés con bases obtusas a subcordadas, nervadura central verde, lóbulos de la corola blancos a amarillos con márgenes incisos a cortamente laciniados y frutos en bayas indehiscentes. Se proporcionan para la especie nueva fotografías digitales, comparaciones morfológicas detalladas con las especies similares y una evaluación preliminar de riesgo de extinción de acuerdo con los criterios de la UICN. | ||||||||
| 3:26p | [Herpetology • 2024] Tylototriton gaowangjienensis • A New Species of the Asian Newt Genus Tylototriton (Urodela: Salamandridae) from Hunan Province, China
Abstract The newt genus Tylototriton is widely distributed in east, southeast, and south Asia. Previous studies have shown that basic surveys of this genus are far from comprehensive, and unknown species still exist within the group. In this study, we described a new species of this genus, Tylototriton gaowangjienensis sp. nov., from Gaowangjie National Nature Reserve in Hunan Province, China, based on evidence from molecular identification and morphological comparisons. Additionally, we conducted phylogenetic analysis of the genus to elucidate the taxonomic status of the new species. Based on combined mitochondrial 16S rRNA and ND2 gene sequences, the phylogenetic tree supported the new species as a member of the T. wenxianensis species subclade in the subgenus Yaotriton. It can be distinguished from its congeners by the combination of the following characteristics: (1) medium-sized body; (2) finger tips extending beyond the snout while forelimbs stretched forward; (3) tips of forelimbs and hindlimbs reaching and overlapping when folded towards the body; (4) snout edge round; (5) absence of small papillae in the male cloacal fissure; (6) dorsal ridges narrow, with width smaller than the eye diameter; (7) head length (HDL) greater than head width (HDW) (HDL/HDW = 1.04~1.22); (8) orange markings absence on the parotoid; (9) nodule-like warts on body sides continuous; (10) vomerine teeth not connected at the tip, extending to the occipital bone at the posterior end. Key Words: morphology, new species, phylogeny, taxonomy
Tylototriton gaowangjienensis J. Huang, Y. Xiang, Y.-X. Zhang, T. Wu & W.-S. Jiang, sp. nov. Diagnosis: The new species can be distinguished from other members of Tylototriton by the following combination of characteristics: (1) medium-sized body; (2) finger tips extending beyond the snout while forelimbs stretched forward; (3) tips of forelimbs and hindlimbs reaching and overlapping when folded towards the body; (4) snout edge round; (5) absence of small papillae in the male cloacal fissure; (6) dorsal ridges narrow, with width smaller than the eye diameter; (7) head length (HDL) greater than head width (HDW) (HDL/HDW=1.04~1.22); (8) orange markings absence on the parotoid; (9) nodule-like warts on body sides continuous; (10) vomerine teeth not connected at the tip, extending to the occipital bone at the posterior end. Etymology: The new species is named after its type locality. We suggest the Chinese name “高望界疣螈” (pinyin: Gāo Wàng Jiè Yóu Yuán), and the English name Gaowangjie Crocodile Newt.
