| 5:03a | [Ichthyology • 2015] Mahseers Genera Tor and Neolissochilus (Teleostei: Cyprinidae) from southern Vietnam
Abstract Two new species and two new basin records of mahseers in the genera Tor and Neolissochilus are described from the upper Krong No and middle Đồng Nai drainages of the Langbiang Plateau in southern Vietnam. These new species and new records are known from streams and rivers in montane mixed pine and evergreen forests between 140 and 1112 m. Their populations are isolated in the Sre Pok River of the Mekong basin, the middle of the Đồng Nai basin, and the An Lão River. Both new species are differentiated from their congeners by a combination of the following characters: 23–24 lateral scales, 9–10 predorsal scales, 2/7 or 1/8 pelvic-fin rays, mouth position, median lobe of lower lip, rostral hood, colour in life and by divergent mitochondrial DNA. Tor mekongensis sp. nov. is differentiated from Tor dongnaiensis sp. nov. by the number of transverse scale rows (3/1/2 vs. 4/1/2), number of pelvic-fin rays (2/7 vs. 1/8), a blunt rostral hood vs. pointed, caudal-fin lobes that are equal vs. unequal, and by mitochondrial DNA (0.7% sequence divergence). Molecular evidence identifies both species as members of the genus Tor and distinct from all congeners sampled (uncorrected sequence divergences >1.9% for all Tor species for which homologous COI sequences are available). Tor sinensis is recorded in the Krong No and the Sre Pok rivers, further south of its known distribution. Polymorphism is described in Neolissochilus stracheyi with a Tor-like morph and a Neolissochilus-like morph. Keywords: Pisces, Langbiang Plateau, Tor dongnaiensis sp. nov., Tor mekongensis sp. nov., Tor sinensis, Neolissochilus stracheyi, southern Vietnam

| 8:07a | [Entomology • 2010] A Survey of the Emesine Assassin Bugs of the Tribes Collartidini, Leistarchini, Emesini, and Metapterini of Taiwan (Hemiptera, Heteroptera, Reduviidae)
Abstract Thread-legged assassin bugs (Hemiptera: Heteroptera: Reduviidae: Emesinae) belonging to the tribes Collartidini, Leistarchini, Emesini, and Metapterini of Taiwan are surveyed. Eight genera and thirteen species are recognized, four species are described as new. Collartidini (represented by the genus Collartida Villers, 1949) is recorded for the first time not only from Taiwan but from Southeast Asia as well. Ploiaria ryukyuana Ishikawa & Tomokuni, 2002, Gardena albiannulata Ishikawa, 2005, and Stenolemus crassirostris Stål, 1871 are recorded for the first time from Taiwan. The species Collartida peregrina sp. n., Bagauda zigzag sp. n., Ploiaria huangorum sp. n., and Stenolemus alikakay sp. n. are described as new. Identification keys to the species of the above tribes occurring in Taiwan are presented, and their zoogeography is briefly discussed.

| 3:28p | [Herpetology • 2016] Leptobrachella itiokai • A New Highland Species of Dwarf Litter Frog Genus Leptobrachella (Anura: Megophryidae) from Sarawak
Abstract A new highland species of the dwarf litter frog, Leptobrachella itiokai, is described from Gunung Mulu National Park, northern Sarawak, East Malaysia. It occurs syntopically with another highland species, L. brevicrus, but differs from it by a unique call that may be described as a chirp, with dominant frequency of ca. 10 kHz. The new species is morphologically distinguishable from congeners by the combination of the following traits: rounded ventrolateral glands usually not in series; side of body with small black spots; ventrum entirely dark-coloured with tiny light spots; male with thread-like lineae masculinae. Key words: Leptobrachella, MtDNA; Phylogeny; Taxonomy; Borneo  Koshiro Eto, Masafumi Matsui and Kanto Nishikawa. 2016.
