Two new genera of Epilachnini Mulsant from New Guinea and Aru Islands (Coleoptera: Coccinellidae)

Abstract

The species formerly classified in the genus Afidentula Kapur from New Guinea and Aru Islands are revised. As a result of detailed analysis of mouth parts and genital structures of the species, two new genera are proposed: monotypic Lalokia gen. nov. from Aru Islands and New Guinea, with Lalokia aruensis (Crotch) (comb. nov.), and Papuaepilachna gen. nov. from New Guinea including Papuaepilachna bivacana (Bielawski) (comb. nov.), P. kapuri (Bielawski) (comb. nov.), P. nasti (Bielawski) (comb. nov.), P. tenmana (Bielawski) (comb. nov.), P. watalai (Jadwiszczak) (comb. nov.) and P. wiebesi (Bielawski) (comb. nov.). All species are illustrated and an identification key to the species of Papuaepilachna is provided. A key to the genera of Epilachnini from New Guinea and Aru Islands is also provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F721B07F-CBF0-4516-853D-1FD434FE06F1
