Flat darkling beetle Cossyphus odewahni, from Matthews & Bouchard (2008).

Belongs within: Tenebrionidae.
Contains: Laena, Adeliini, Lagriina, Statirina.

The Lagriinae are a group of tenebrionid beetles with alae on the aedeagus, articulated to the apical piece by a membrane. Members of the tribes Belopini and Cossyphini have tentyrioid hinging down the mid-line between the abdominal ventrites whereas the remaining tribes have tenebrionoid hinging laterally. Belopini are small tenebrionids, often with reduced numbers of antennal and tarsal segments (Matthews & Bouchard 2008).

Characters (from Matthews & Bouchard 2008): Corpotentorium often present, not arched. Mandibular mola with a few coarse transverse ridges, not finely striate. Elytral striae, when present, 10 plus scutellary striole. Tarsomeres frequently lobed or cupuliform. Ovipositor usually of primitive type, with digitate fourth coxite lobe bearing gonostyles apically. Female tract usually with colleterial glands (sometimes modified into defensive glands). Aedeagus with alae articulated to apical piece by a membrane.
