Orectoscelis

AntWiki: The Ants --- Online


There are eighteen species in this myrmecophilous genus of Histeridae. Orectoscelis is herein restricted to those species with a completely hidden scutellum and circular, usually obliquely elevated humeral trichomes, fringed by a single continuous setal margin. Several species placed here by Caterino (2000) are removed to other genera, whereas a few others described therein are retained here with reservation.

The combined distribution of the species included here ranges from northern Australia (both Queensland and Northern Territory) through New Guinea, north-west to Sulawesi
