Coleoptera Hydnocerinae new genus hydnocerine subtribe key to species Costa Rica species discovery


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.
