The genus Chabria Jacoby: First records in the Afrotropical region with description of three new species from Madagascar and annotated worldwide species catalogue (Coleoptera, Chrysomelidae, Galerucinae, Alticini)

Abstract

The Oriental flea beetle genus Chabria Jacoby, 1887 for the first time is reported from the Afrotropical region. Three new species, Chabria betsilea sp. n., C. betsimisaraka sp. n., C. bezanozana sp. n., are described from Madagascar, while C. angulicollis (Clark, 1865), probably accidentally introduced in Sub-Saharan Africa, is reported from Cameroon and Republic of South Africa. A key to the Afrotropical Chabria species, scanning electron micrographs of some diagnostic morphological characters, micrographs of male and female genitalia are provided. In addition, an annotated catalogue of all worldwide known species of Chabria Jacoby based both on literature and new examined material is also provided. Finally, the presence of Chabria in Sub-Saharan Africa and in Madagascar is discussed.
