Microdytes Balfour-Browne of India with description of three new species (Coleóptera: Dytiscidae: Hydroporinae)

摘要

Three new species in the genus Microdytes Balfour-Browne (Coleóptera: Dytiscidae) are described from southwestern India: M. cameroni n. sp., M. svensoni n. sp. and M. whitingi n. sp. A key to the ten species of the genus Microdytes currently known from India is provided, and some new records of Indian Microdytes are given. Microdytes Balfour-Browne is a species-rich genus with members occurring throughout southern and southeastern Asia from Nepal to southern India to southern China, southern Japan,Philippines and Indonesia. Prior to this paper there were 36 described species. The genus was revised by Wewalka (1997) who added 21 new species to the nine known prior to his work. Four additional new species were described by Wewalka (1998) and Wewalka& Wang (1998). Wewalka, Ribera & Balke (2007) and Bian &Ji (2009) recently added two new species.
