Chnoodes Chevrolat, 1849 currently has 32 species described in South and Central America, with only one species, Chnoodes centralis Sicard, 1912 described from French Guiana. Here, C. centralis is redescribed and five new species are described: C. brulei sp. nov. (holotype male: Commune de Roura, Montagne des Chevaux), C. rubra sp. nov. (holotype male: Commune de Roura, Montagne des Chevaux), C. cerasus sp. nov. (holotype male: Commune de Roura, Montagne des Chevaux), C. tristis sp. nov. (holotype male: Commune de Kourou, Savane des Pères) and C. melanus sp. nov. (holotype male: Commune de Régina, Réserve Naturelle des Nouragues). These species can be distinguished by body color, presence or absence of spots on the pronotum and elytra, and by male and female genitalia. A distribution map and a key for the species in French Guiana are provided.
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. (Holotype female deposited in DZUP: Amapá State, Oiapoque municipality, V.1959, M. Alvarenga leg.). They can be distinguished 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
