A new species of Oileus Kaup (Coleoptera, Passalidae) from Guatemala, with a key to the species of the genus

Abstract

Oileus gasparilomi sp. n. is described from nine specimens from the mountains of Quiché in Guatemala, from cloud forest at 1795 m elevation. This represents the second species of the genus for Guatemala, differing from the closely related Mexican species Oileus rimator (Truqui) in having a straight anterior clypeal border, the postocular sulcus divided by a keel and the pronotum almost straight (not clearly bilobed). A key to the species of Oileus is given. © Enio B. Cano, Jack C. Schuster.
