New relictual genera in Cyrtoquediini and Indoquediini (Coleoptera: Staphylinidae: Staphylininae)

Abstract

Sundaquediusgen. nov. (Cyrtoquediini) and Fluviphirusgen. nov. (Indoquediini) are described from southeast Asia and western North America, respectively, resulting in the new combinations Sundaquedius nigropolitus (Cameron) and Fluviphirus elevatus (Hatch). Sundaquedius abbreviatussp. nov. is described from Vietnam. The phylogenetic positions of these genera within Staphylininae are supported by morphology and recently published phylogenomic evidence. New keys to the world genera of Cyrtoquediini and Indoquediini are provided. A new country record for Alesiella lineipennis (Cameron) is provided for Thailand, based on the first available specimen in more than 100 years.
