Description of the new genus Tarsobaenus and three new species from Costa Rica (Coleoptera: Cleridae: Clerinae: Hydnocerini)

摘要

The new genus Tarsobaenus and three new species-Tarsobaenus letourneauae, T. piper and T. hansoni-are described from Costa Rica. Tarsobaenus is distinguished by the broad, subulate form of the plical excavation along the elytral suture, the lower margin of which is modified into a broad flattened flange; serrulate apical elytral margins; and the conspicuously large, shiny body. Two of the species are associates of Piper plants and their pharaoh ant symbionts. We provide a key to the three species of Tarsobaenus.
