Revision of Tegyrius (Coleoptera: Chrysomelidae: Galerucinae: Alticini), with descriptions of eight new species

Abstract

The flea beetle genus Tegyrius Jacoby, 1887 (Coleoptera: Chrysomelidae) associated with Piperaceae is revised. Eight new species, namely Tegyrius agasthyai sp. nov., Tegyrius dalei sp. nov., Tegyrius nigrotibialis sp. nov., Tegyrius pucetibialis sp. nov., Tegyrius radhikae sp. nov., and Tegyrius tippui sp. nov., from India, and Tegyrius anupama sp. nov. and Tegyrius buddhai sp. nov., from Sri Lanka, are described and illustrated. Key to species and host plant information are also provided. Tegyrius piceus Kimoto, 2001 is transferred to Longitarsus Latreille, 1829 (new combination); Tegyrius antennatus (Medvedev, 2001), Tegyrius bicolor (Medvedev, 2001) (both earlier Lankaphthona), and Tegyrius keralaensis (Doeberl, 2003) (earlier Ogloblinia) are proposed as new combinations. © 2009 The Linnean Society of London.
