A new genus and species of Neotropical Hybosorinae Erichson, 1847 (Coleoptera: Hybosoridae)

Abstract

Among the 26 Hybosorinae genera, seven are present exclusively in the Neotropical region. However, Hybosorinae from the New World have been less studied. One new genus and new species collected in Brazil is herein described to this subfamily.The genus is recognizable by the following combination of characters: labium with semicircular mentum; mandibles with lateral projection excavated, separated in the middle by longitudinal carina, inner side sheltering the labrum; antennae with nine antenomeres; scutellar shield with strong punctures at the proximal half; elytra with single rows formed by punctures; and protibia without well-defi ned denticles.
