title: Ogyges Kaup, a flightless genus of Passalidae (Coleoptera) from Mesoamerica: nine new species, a key to identify species, and a novel character to support its monophyly.
abstract: Nine new species of Ogyges Kaup (Coleoptera: Passalidae) from the mountainous cloud forests of Mesoamerica are described: O. handali new species and O. menchuae new species from Guatemala; O. cavei new species, O. laurae new species, O. llama new species, O. mutenroshii new species, O. ratcliffei new species, and O. toriyamai new species from Honduras; and O. sandinoi new species from Nicaragua, the first objective record of the genus for this country. A key to the adult Ogyges is included. The work also shows that Ogyges possesses an exclusive autapomorphy: a trituberculate suprainternal tooth of each mandible (one long and wide apical tubercle and two connected, small, almost conical, basal tubercles). This character state is found in all known Ogyges species and is proposed as a synapomorphy that supports the monophyly of the genus.
