| 8:30a | [Botany • 2020] Rhododendron pudingense (Ericaceae: Subgen. Tsutsusi) • A New Species of Rhododendron from Guizhou, China
Abstract A new species of the Rhododendron (Ericaceae) in subgen. Tsutsusi sect. Tsutsusi from Puding county of Guizhou, China, is described and illustrated. The new species, Rhododendron pudingense X.Y. Dai, C.H. Yang & Y.P. Ma, is similar to R. myrsinifolium Ching ex Fang et M. Y. He and R. minutiflorum Hu, but it can be easily distinguished by its length and being pubescent on inner surface of corolla tube, sparse hairs below the middle of filament and the glabrous style. Keywords: China, Ericaceae, Guizhou, Rhododendron, R. pudingense, Tsutsusi
  Rhododendron pudingense X.Y. Dai, C.H. Yang & Y.P. Ma., sp. nov. Etymology: The specific epithet is named after the type locality Puding County, in which this plant was first discovered. Vernacular name: Chinese mandarin: pǔ dìng dù juān (普定杜鹃) Distribution and habitat: So far, this species is only known from the type locality (Pudding County) and from the Wangmo County, Guizhou Province, southwest China. At these locations Rhododendron pudingense grows in evergreen and deciduous broad leaved mixed open forests within the rock cracks of limestone hills, at an elevation of 1300 m to 1400 m.

| 9:03a | [Crustacea • 2020] Triacanthoneus blanca • Taxonomic Remarks on the Alpheid Shrimp Genus Triacanthoneus Anker, 2010 (Malacostraca: Decapoda), with Description of A Second eastern Pacific Species
Abstract The recently described alpheid genus Triacanthoneus Anker, 2010 is reassessed based on new material from the Pacific and Caribbean coasts of Panama, and the southern Gulf of Mexico. Salmoneus armatus Anker, 2010 is tentatively transferred to Triacanthoneus and the latter genus is redefined. A new eastern Pacific species of Triacanthoneus is described based on a single specimen collected by scuba diving off Coiba Island on the Pacific coast of Panama. Triacanthoneus blanca sp. nov. is closely related to its only eastern Pacific congener, T. pacificus Anker, 2010, which is reported for the first time from the Las Perlas Islands in the Gulf of Panama. Morphological variation in T. toro Anker, 2010 is discussed on the basis of new topotypical material from Bocas del Toro, Panama, and a single specimen tentatively reported as T. cf. toro from Sisal, Mexico. An identification key to the seven currently known species of Triacanthoneus, with updated distributional and ecological information, as well as high-resolution colour photographs of four species are also provided.

| 11:54a | [Entomology • 2020] A Revision of the Genus Morphostenophanes Pic, 1925 (Coleoptera, Tenebrionidae, Stenochiinae, Cnodalonini)
Abstract The genus Morphostenophanes Pic, 1925 is redefined and revised. Seventeen new species and three new subspecies are described, including M. aenescens yelang Zhou, new subspecies, M. bannaensis Zhou, new species, M. brevigaster Zhou, new species, M. chongli Zhou, new species, M. crassus Zhou, new species, M. furvus Zhou, new species, M. furvus weishanus Zhou, new subspecies, M. gaoligongensis Zhou, new species, M. iridescens Zhou, new species, M. lincangensis Zhou, new species, M. linglong Zhou, new species, M. metallicus Zhou, new species, M. minor, Zhou, new species, M. planus Zhou, new species, M. purpurascens Zhou, new species, M. sinicus Zhou, new species, and M. yunnanus Zhou, new species from Yunnan, China; M. chongli glaber Zhou, new subspecies from Yunnan, China and North Vietnam; M. curvitibialis Zhou, new species from Guangxi, China, and M. luoxiaoshanus Zhou, new species from Hunan, Hubei and Jiangxi, China. M. birmanicus (Kaszab, 1980) is recorded from China (Yunnan) for the first time. M. papillatus Kaszab, 1941 is firstly recorded from Yunnan and Sichuan, China. Two poorly known species, M. aenescens Pic, 1925 and M. vietnamicus Kaszab, 1980 are redescribed. Male of M. atavus (Kaszab, 1960) is described in detail. Misidentifications of M. aenescens Pic. 1925 and M. atavus (Kaszab, 1960) in previous works are corrected. Six species groups are proposed. A species catalog, identification key and distributional maps for the genus are given.
