| 2:27a | [Crustacea • 2024] Garymunida namora, Trapezionida macilenta, T. pulex, etc. • DNA Barcoding and Morphology revealed the Existence of Seven New Species of Squat Lobsters in the Family Munididae (Decapoda: Galatheoidea) in the southwestern Pacific
Abstract Specimens of squat lobsters belonging to the family Munididae Ahyong et al., 2010, representing the genera Garymunida Macpherson & Baba, 2022, Trapezionida Macpherson & Baba, 2022 and Typhlonida Macpherson & Baba, 2022, were collected during several cruises around New Caledonia and Papua New Guinea, Southwest Pacific. The integrative study of these specimens revealed the presence of one new species in Garymunida, five in Trapezionida and one in Typhlonida. We describe and illustrate these new species, providing some new data on the taxonomy of several rare or scarcely studied species of Trapezionida. Molecular data from different markers (mitochondrial and nuclear) was also included, based on data availability, to support the taxonomic status of different species. Finally, a key to species for each genus is also provided.

| 3:04a | [Botany • 2022] Thrixspermum patkaiensis (Orchidaceae: Vandeae: Aeridinae) • A New Species from Assam, northeast India
Abstract A new species of orchid, Thrixspermum patkaiensis from the tropical evergreen forest in Dehing Patkai National Park, Assam, India, is described. It is morphologically similar to T. musciflorum and T. formosanum but distinct from these species by the inflorescence 12–18 cm long; the lip with purplish bands and glandular hairy both side of the side lobes and the epichile forming a rim of glandular hairs. Keywords: Dehing Patkai, Flora of India, plant taxonomy, Thrixspermum formosanum, Thrixspermum musciflorum, Thrixspermum pygmaeum, Thrixspermum section Dendrocolla    Thrixspermum patkaiensis K.Gogoi, sp. nov. Diagnosis: The present new species is morphologically similar to Thrixspermum musciflorum A.S.Rao & Joseph, T. formosanum (Hayata) Schltr., and T. pygmaeum (King & Pantl.) Holttum, but differs from these species by the 12–18 cm long inflorescence with 2.5–5.0 cm long rachis; yellow or pale-yellow flowers; lip yellow with white or pale yellow in-front, streaked with purplish stripes and glandular-hairy on both sides of the lateral lobes; epichile forming a glandular hairy rim and the disk with long hairs. Etymology: The specific epithet refers to the Dehing Patkai National Park, Assam in Northeast India where from the plant was collected. Khyanjeet Gogoi. 2022. Thrixspermum patkaiensis sp. nov.

| 9:30a | [Ichthyology • 2023] Luciogobius griseus • A New subtropical Species of Goby of the Genus Luciogobius (Gobiiformes: Gobiidae) from southwestern Japan
Abstract Luciogobius griseus n. sp., belonging to the Luciogobius platycephalus complex, is described on the basis of 40 specimens from the Nansei Islands, southwestern Japan (subtropical area). The new species is generally found in intertidal gravel sediments subjected to freshwater runoff from springs on coastal lines or river mouths and is characterized by the following combination of characters: total second dorsal-fin rays 9–12 (modally 11); total anal-fin rays usually 12–14 (modally 13); pectoral-fin rays 12–15 (modally 13); vertebrae 17 or 18 + 23 or 24 = 40–42 (18 + 23 = 41); uppermost 2–4 (2–3) rays on pectoral fin free; 8–12 pectoral-fin rays branched (uppermost free rays and sometimes lowermost ray unbranched); pectoral-fin membrane not strongly concave anteriorly (except for free rays); pelvic fins united, forming a disk; head relatively short, 13.9–20.8% of standard length (SL); relatively short pre-pelvic fin, length 14.4–22.1% of SL; relatively long pre-dorsal fin, length 68.9–72.9% of SL; relatively long pre-anal fin, length 63.5–67.7% of SL; relatively short pelvic fin, length 2.8–4.7% of SL; distance between posterior end of pelvic fin and anus relatively long, 32.0–36.4% of SL (aforementioned morphometrics each distinguishing L. griseus n. sp. from other species in the L. platycephalus complex); and fresh specimens with greenish dark brown or gray body. A key to the L. platycephalus complex is provided, together with limited descriptions and remarks on the other two members of the complex.
