A new genus and species of hisponine jumping spider from Sarawak, Jerzego corticicola Maddison sp. nov. are described, representing one of the few hisponine jumping spiders known from Asia, and the only whose male is known. Although similar to the primarily-Madagascan genus Hispo in having an elongate and flat body, sequences of 28s and 16sND1 genes indicate that Jerzego is most closely related to Massagris and Tomomingi, a result consistent with morphology. Females of Jerzego and other genera of Hisponinae were found to have an unusual double copulatory duct, which appears to be a synapomorphy of the subfamily. Two species are transferred from Hispo, Jerzego bipartitus (Simon) comb. nov. and Jerzego alboguttatus (Simon) comb. nov. Diagnostic illustrations and photographs of living spiders are provided.
Six new species of marpissoid jumping spiders from Sarawak, Borneo, are described in the new genus Tisaniba Zhang & Maddison. They are the type species, T. mulu Zhang & Maddison sp. nov., as well as the species T. bijibijan Zhang & Maddison sp. nov., T. dik Zhang & Maddison sp. nov., T. kubah Zhang & Maddison sp. nov., T. selan Zhang & Maddison sp. nov., and T. selasi Zhang & Maddison sp. nov. The spiders are small and brown to black, living in leaf litter in the tropical forest. Phylogenetic analyses based on 28s and 16sND1 genes indicate that they are a distinctive group within the marpissoids. Diagnostic illustrations and photographs of living spiders are provided for all species.
Two new genera of euophryine jumping spiders in the Laufeia group are established for species from Southeast Asia: Amoenema Yu & Zhang, gen. nov. and Lokina Yu, Maddison & Zhang, gen. nov., with descriptions of 12 new species: Amoenema erhai Yu & Zhang, sp. nov. (♂♀, type species), A. liuae Yu & Zhang, sp. nov. (♂♀), A. zizhongi Yu & Zhang, sp. nov. (♂♀), Lokina blombergi Yu, Maddison & Zhang, sp. nov. (♂♀), L. chiyou Yu & Zhang, sp. nov. (♂♀, type species), L. fuxi Yu & Zhang, sp. nov. (♂♀), L. kubah Yu, Maddison & Zhang, sp. nov. (♂), L. nyuewa Yu & Zhang, sp. nov. (♂♀), L. pixi Yu, Maddison & Zhang, sp. nov. (♂), L. tamasi Yu & Zhang, sp. nov. (♂♀), L. wuyi Yu & Zhang, sp. nov. (♂), L. zhishengi Yu & Zhang, sp. nov. (♂). In addition, three new combinations are proposed: Amoenema robusta (Lei & Peng, 2012) comb. nov. (transferred from Euophrys C. L. Koch, 1834), Lokina eximia (Zhang & Maddison, 2012) comb. nov. (transferred from Laufeia Simon, 1889) and L. tengchongensis (Lei & Peng, 2012) comb. nov. (transferred from Chalcovietnamicus Marusik, 1991).
The genus Kelawakaju Maddison & Ruiz, gen. nov., is described for a lineage of bark-dwelling Asian marpissine jumping spiders that represent a dispersal to Eurasia separate from that of the Marpissa-Mendoza lineage, according to the phylogeny recovered from analysis of four gene regions. All species of Kelawakaju are new to science except Kelawakajufrenata (Simon, 1901), comb. nov., which is transferred from Ocrisiona Simon, 1901. Kelawakajufrenata is known from Hong Kong, Guangdong, Guangxi, and likely Taiwan. The five new species are Kelawakajumulu Maddison & Ruiz, sp. nov. (type species of Kelawakaju, from Sarawak, Malaysia, ♂♀), K.intexta Maddison & Ruiz, sp. nov. (from Sarawak, ♂), K.leucomelas Maddison & Ng, sp. nov. (Singapore and Johor Bahru, ♂♀), K.sahyadri Vishnudas, Maddison, & Sudhikumar, sp. nov. (India, ♂♀), and K.singapura Maddison & Ng, sp. nov. (Singapore, ♂♀).
