Comparative Morphology of the Larvae of the Rove Beetles of Paederus , Lathrobium , and Tetartopeus , With Notes on its Systematic Position (Coleoptera: Staphylinidae: Paederinae)

The mature larvae of the rove beetles (Coleoptera: Staphylinidae) Lathrobium lineatocolle Scriba and Tetartopeus quadratus (Paykull) are described for the first time, and the larva of Paederus littoralis Gravenhorst is redescribed. Detailed illustrations of their structural features are provided. The description of T. quadratus is the first for that genus. Diagnostic larval, morphological characters for Paederus , Lathrobium , and Tetartopeus are proposed. Based on the earlier published and new data, morphological comparisons at the subtribal and genus levels within the subfamily Paederinae are given. The principal differences among subtribes and genera involve structures located on the head, but several relate to abdominal sclerites and urogomphi. Based on the current data, the previously proposed characters diagnostic for the subfamily Paederinae are verified. A status of Paederidus and Tetartopeus as genera as opposed to their subgeneric status within Paederus and Lathrobium , respectively, was confirmed.
