| 3:55a | [Botany • 2025] Pleurothallis machupicchuensis (Orchidaceae: Pleurothallidinae) • A New Species from the Historic Sanctuary of Machupicchu, Perú
Abstract Pleurothallis machupicchuensis, a new species from Cusco, Perú, is described and illustrated. Information regarding its distribution, habitat, and phenology is provided. Morphologically, P. machupicchuensis closely resembles P. scurrula and P. sannio but can be distinguished mainly by the morphology of the lip. The new species features an ovate, obtuse lip with a prominent bilobed, reniform glenion, in contrast to the oblong-ovate, acute lip with a small rounded glenion observed in P. scurrula, and the ovate, rounded lip with an oblong glenion in P. sannio. Key words: Andes, biodiversity, Cusco, Inkaterra
Pleurothallis machupicchuensis Damián-Parizaca, Monteros & Coayla, sp. nov. Diagnosis. Pleurothallis machupicchuensis is most similar to Pleurothallis scurrula Luer but differs by the obtuse dorsal sepal (vs. acute), the acute synsepal apex (vs. obtuse to rounded), the falcate petals (vs. oblong-ovate), the ovate lip (vs. oblong), and the reniform bilobed glenion (vs. oblong non bilobed).
Etymology. The epithet honors the llaqta Machupicchu, an Inka citadel in Cusco, southern Peru, located within the Urubamba Province, where P. machupicchuensis is locally distributed.

| 12:00p | [Crustacea • 2025] Geosesarma bunian • On A New Species of Vampire Crab from the Geosesarma foxi species-group (Brachyura: Sesarmidae) in northern Peninsular Malaysia
Abstract Geosesarma bunian, new species, is described from Gunung Jerai in the northern Malaysian state of Kedah. Collected from over 1,100 m above sea level, the species is a member of the G. foxi (Kemp, 1918) species group, and is the fifth species known. Morphologically, G. bunian is closest to G. faustum Ng, 2017 from Penang, but the species can be distinguished by characters of the male first gonopod, male chelae and live coloration. Key words. taxonomy, Kedah, Peninsular Malaysia, Gunung Jerai, comparative morphology, Southeast Asia
Family Sesarmidae Dana, 1851 Genus Geosesarma De Man, 1892 Type species. Sesarma (Geosesarma) nodulifera De Man, 1892, subsequent designation by Serène & Soh (1970). Geosesarma bunian, new species Diagnosis. Carapace quadrate, as wide as long, adult width to length ratio ca. 1.0, lateral margins parallel (Figs. 2, 4A, B); dorsal surface with regions just visible, anterior regions with small, low rounded granules on gastric regions (Figs. 2C, D, 4A, B); front distinctly deflexed, 2 frontal lobes broad with almost straight margins in dorsal view; postfrontal, postorbital cristae sharp, distinct (Figs. 2C, D, 3A, 4A, B); external orbital tooth (= first lateral tooth) triangular, directed obliquely laterally, outer margin gently convex to almost straight, tip extending just beyond lateral margin; second lateral tooth low, distinct, separated from rest of margin by cleft (Figs. 2C, D, 4A, B). Merus of third maxilliped subovate, shorter than ischium; exopod slender ... Etymology. The name is derived from a Malay term used to describe the “hidden people” of the forest or Orang Bunian. They are often described as beautifully dressed forest denizens. The name, bunian, here used as a Latin noun in apposition, alludes to the beautiful colours of the new species as well as it escaping scientific attention until now. Peter K. L. NG, S.

| 2:52p | [Herpetology • 2023] Cyrtodactylus caixitaoi • A New Species of Cyrtodactylus Gray, 1827 (Squamata: Gekkonidae) from Yunnan, China
Abstract A new species of the Cyrtodactylus chauquangensis species group is described from Yunnan Province, China, based on morphological and molecular data. The new species closely resembles C. wayakonei morphologically, but can be separated from the latter by having more white rings on original tail, more lamellae under finger IV and toe IV, less longitudinal ventral scale rows, and enlarged femoral scales. However, the new species is closely related to C. martini rather than C. wayakonei genetically. The new species differs from C. martini by genetic distance of 3.3% and from investigated other members of the C. chauquangensis species group by genetic distances of 6.4 – 17.8% in the COI gene. Keywords: bent-toed gecko; China; systematics; taxonomy; Xishuangbanna; Yunnan
Cyrtodactylus caixitaoi sp. nov. Etymology. The epithet is in honor of Prof. Xitao Cai (1911 – 1981), who founded Xishuangbanna Tropical Botanical Garden in 1950s. We propose “Cai’s Bent-toed Gecko” for the English name ... Shuo Liu, Dingqi Rao, Mian Hou, Qiaoyan Wang and Natalia Borisovna Ananjeva. 2023.
