A revision of Neosclerus V. Thirteen new species and additional records (Coleoptera: Staphylinidae: Paederinae).

Abstract

Thirteen species of Neosclerus Cameron, 1924 are described and illustrated: N. albens spec. nov. (Sri Lanka), N. areolatus spec. nov. (Thailand), N. biangulatus spec. nov. (Thailand), N. daweianus spec. nov. (China: Yunnan), N. discolor spec. nov. (Burma, Thailand), N. figens spec. nov. (China: Yunnan), N. forficatus spec. nov. (Sri Lanka), N. fractus spec. nov. (India: Meghalaya), N. khasicus spec. nov. (India: Meghalaya), N. revolutus spec. nov. (South India), N. sagittatus spec. nov. (India: Meghalaya), N. semicalvus spec. nov. (Thailand), and N. trisinuatus spec. nov. (China: Yunnan). The previously unknown male sexual characters of N. granulicollis Cameron, 1924 are described and illustrated. Additional records of twelve named and three unnamed species are reported, among them several new country records. The genus now comprises 44 named species in five species groups, one of them newly established. The countries with the greatest diversity are China, India, and Thailand (ten species each), and Taiwan (nine locally endemic species). The distribution of the genus as a whole, as well as the individual distributions of 34 species are mapped. An updated catalogue is provided.
