Abstract
The mature larva of Platydracus latebricola (Gravenhorst, 1806) is described for the first time and the larva and pupa of Staphylinus erythropterus Linné, 1758 are redescribed. Illustrations of structural features are provided. The combination of characters that allow for distinguishing the known mature larvae of Platydracus, and larvae and pupae of Staphylinus from closely related genera within tribe Staphylinini are given. The mature larvae of Platydracus and Staphylinus are compared and the generic status of the former is confirmed. Life history data under laboratory conditions of S. erythropterus are provided. Two larval instars in this species, a state unique within the tribe Staphylinini was reported.
