Oocyclus Sharp, 1882

Oocyclus Sharp, 1882: 61 (Type species: Oocyclus brevicornis Sharp –des. Knisch, 1924).

Diagnosis. Round to elongate oval, convex to nearly hemispherical. Elytra with or without rows of systematic punctures; if present, often bearing setae; margins not explanate. All ventrites pubescent throughout. Prosternum usually set with a pair of spines or hairs centrally. Mesosternal process often set with articulated spines or hairs. Anterolateral corners of prosternum evenly rounded or less frequently spinose ( O. substillus). Eyes not protruding as in Ophthalmocyclus Komarek. Elytral suture not raised as in Beralitra d’Orchymont.

Discussion. There is considerable variation within the group both published and unpublished (Perkins, unpubl.data; Short, unpubl. data; García pers. comm.). Because this work is limited to only a portion of the species in the New World, a full redescription of the genus should await a comprehensive treatment that examines both Old and New World species. See Komarek (2003) for a brief review of generic­level characters within the ‘ Oocyclus ­group’.
