Two new species of Chnoodes Chevrolat (Coleoptera: Coccinellidae) from Brazil

Abstract

Two new species of Chnoodes from Brazil are described: C. machadoi sp. nov. (Holotype male deposited in DZUP: Mato Grosso State, Cáceres muncipality, 13.XI.1984, Buzzi, Mielke, Elias & Casagrande leg.) and C. unimaculata sp. nov. (Ho-lotype female deposited in DZUP: Amapá State, Oiapoque municipality, V.1959, M. Alvarenga leg.). They can be distin-guished from all previously described species mainly by the yellowish border of the elytra in C. machadoi sp. nov., and the large mid-dorsal pale spots in C. unimaculata sp. nov. Six species are redescribed: Chnoodes brasiliensis Korschefsky, C. chaudoiri Mulsant, C. discomaculata (Crotch), C. pentagona Crotch, C. pseudosanguinea Brèthes, and C.Tarsalis Weise. A key to Brazilian species of Chnoodes and new records are also given.
