Abstract
Based on external structural features and those of the male and female genitalia, the aleocharine staphylinid genus Ligulata, new genus, is proposed and diagnosed, along with L. hansoni, new species (type locality: Costa Rica: San Jose, Zurqui de Moravia). Specimens of L. hansoni were collected using Malaise traps placed within a montane tropical evergreen forest. Among members of the Hoplandriini, Ligulata is most similar to the genus Bessoglossa Pace 1986 and share the following possible synapomorphies: ligula long with numerous setae at apex; and hypoglossal lobes long, comb-like with long, internally curved setae.
