Kelawakaju gen. nov., a new Asian lineage of marpissine jumping spiders (Araneae, Salticidae, Marpissina).

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, ♂♀).
