Revision of Oriental flea beetle genera with subparallel intercoxal ridges on the first abdominal ventrite (Coleoptera, Chrysomelidae, Galerucinae, Alticini)

ABSTRACT

The Oriental flea beetle genera (Coleoptera, Chrysomelidae, Galerucinae, Alticini) with subparallel intercoxal ridges on the first abdominal ventrite are revised. Sahyadrialtica stephaniae gen. nov. and sp. nov. from south India are described. The following new synonyms are proposed: Lankanella Kimoto, 2000 syn. nov. (= Parategyrius Kimoto and Gressitt, 1966), Lankaphthona Medvedev, 2001 syn. nov. (= Parategyrius Kimoto and Gressitt, 1966), Paraphthona Medvedev, 2009 syn. nov. (= Parategyrius Kimoto and Gressitt, 1966) and Neorthella Medvedev, 2010 syn. nov. (= Lanka Maulik, 1926). Sphaeraltica Ohno, 1961 is proposed as the new replacement name for Ogloblinia Csiki, 1940 instead of Lesagealtica Döberl, 2009. New combinations are proposed due to the new and previously published synonyms. A checklist, comprising 96 species belonging to 10 genera in the Tegyrius genus group, is provided.
