| 7:26a | [Mammalogy • 2022] Chodsigoa dabieshanensis • A New Species of Asiatic Shrew of the Genus Chodsigoa (Eulipotyphla: Soricidae) from the Dabie Mountains, Anhui Province, eastern China
Abstract Asiatic shrews of the genus Chodsigoa (Soricidae, Eulipotyphla) currently comprise nine species, mostly occurring in southwest China. From May 2017 to August 2020, 11 specimens of Chodsigoa were collected from the Dabie Mountains in Anhui Province, eastern China. Their morphology was compared with other species within the genus and one mitochondrial (cytochrome b) and two nuclear (apolipoprotein B and breast cancer 1) genes were sequenced to estimate the phylogenetic relationships of these specimens. Based on morphological and molecular evidence, these specimens are recognized as a distinct species, Chodsigoa dabieshanensis sp. nov., which is formally described here. Morphologically, the new species is most similar to Chodsigoa hypsibia, but it is distinguishable from all known congeners by the combination of dark brownish pelage, small size, and relatively short tail. Phylogenetic analyses revealed that C. dabieshanensis sp. nov. forms a phylogenetic lineage sister to the clade containing C. parva + C. hypsibia. The-Kimura 2-parameter genetic distances of the cytochrome b (CYT B) gene between the new species and other nominal Chodsigoa species ranged between 8.6 and 17.6%. The new species is distributed at elevations from 750 to 1250 m in the Dabie Mountains and is geographically distant from other species in the genus. Keywords: Chodsigoa dabieshanensis, molecular analysis, morphology, new species, taxonomy
Chodsigoa dabieshanensis sp. nov. Suggested common name: Dabieshan long-tailed shrew; 大别山缺齿鼩 (Dabieshan Quechiqu) Diagnosis: The new species is assigned to the genus Chodsigoa for having three upper unicuspid teeth, with the tips of the teeth lightly pigmented (Fig. 4). Chodsigoa dabieshanensis sp. nov. can be distinguished from the other known species of Chodsigoa by the following combination of characters: small to medium in size (HB = 67.22 mm; CIL = 19.08 mm), dark brownish pelage; tail shorter than the HB, nearly similar ventral and dorsal pelage color, a small tuft of longer hairs at the tip of the tail (Fig. 5); markedly flattened braincase; and the foramen magnum is relatively wider than C. hypsibia. Phylogenetic analyses show that the new species is monotypic, sister to C. hypsibia and C. parva (Fig. 3). Etymology: The specific name dabieshanensis is derived from the Dabie Mountains, the type locality of the new species: -shan means mountain in Chinese, and the Latin adjectival suffix -ensis means “belonging to". Distribution and habits: Chodsigoa dabieshanensis sp. nov. is currently known from Yaoleping National Nature Reserve, Bancang Natural Reserve, and Foziling Natural Reserve, all located in the Dabie Mountains, Anhui province, eastern China. Most specimens were collected from deciduous broad-leaf forests at 750–1250 m a.s.l. Zhongzheng Chen, Tingli Hu, Xiaoxin Pei, Guangdao Yang, Fan Yong, Zhen Xu, Weiying Qu, Kenneth O.

| 7:27a | [Herpetology • 2022] Pristimantis blasi • A New Species of Red-eyed Frog of the Genus Pristimantis (Anura: Strabomantidae) from the Western Slope of the Cordillera Occidental, Risaralda, Colombia
Abstract We describe a new species of red-eyed frog of the genus Pristimantis from the tropical forest at elevations of 1000–1350 m on western slope of the Cordillera Occidental, department of Risaralda, Colombia. The new species differs from congeners by having dorsum skin shagreened with low tubercles; vocal sac single, median and subgular in males, iris red wine in females copper red in males, and by presenting black groin coloration with yellow light blotches. In addition, the new species has concave frontoparietals, an unusual character described in Brachycephaloidea frog species. Keywords: Amphibia, Andes, frontoparietals, Terrarana, taxonomy, new species

| 10:35a | [Botany • 2016] Swertia subuniflora (Gentianaceae) • A New Species from Fujian, China
Abstract Swertia subuniflora is described from Fujian Province, China. Morphological and molecular evidences indicate its close relationship with S. franchetiana, S. mussotii and S. punicea, three species from Swertia series Japonica (further grouped in section Swertopsis, subgenus Ophelia). The new species can be recognized by its solitary flowers and ovate-cordate stem leaves. Keywords: cpDNA, morphology, new taxon, taxonomy, Eudicots
Swertia subuniflora B.H.Chen & S.L.Chen, sp. nov. Etymology:—The specific epithet refers to the flower which is almost solitary on each flowering stem.

| 11:27a | [Botany • 2018] Fritillaria tunievii (Liliaceae) • A New Species from Armenia and North-East Anatolia
Abstract The new peculiar species Fritillaria tunievii Gabrielian with twin flowers is described from Urts mountain range in Yerevan floristic region of Armenia. Revision of herbarium collections of related species revealed this species to grow also in Aragats, Aparan and Darelegis floristic regions of Armenia, and even in North-East Anatolia. Description, holotype image, distinguishing features from F. hajastanica (Gabrielian) Gabrielian, F. caucasica Adams and F. assyriaca Baker, the map of distribution of the species and photos of plants are enclosed. Key words: Fritillaria tunievii, Armenia, North-East Anatolia, new species, distinguishing features, distribution
Fritillaria tunievii Gabrielian, sp. nova (sect. Fritillaria). Affinity. Boris S. Tuniev noted that on Urts mountain range F. tunievii grows together with F. hajastanica (Fig. 3), which occurs from 1000 to 1800 m and more often than the former, which grows solitary or in small groups, mainly on the northern slopes of the mountain ridge at 1750–1850 m. As only these two related species occur on Urts mountain range, the following Table focuses on the distinctive characters of these two. Habitat. Grassy stony slopes, mountain steppes, juniper woodland, subalpine meadows, N or NE slopes, rarely S or SW slopes, at 1400–2500 m. E. Tz. Gabrielian. 2018.
