Cacodaemon Thomson, 1857

Type species.

Eumorphus satanus Thomson, 1856 (designated by Strohecker 1964).

Diagnosis.

The genus Cacodaemon is closely related to the genus Amphisternus Germar, 1843, but differs from it by the following characteristics: elytral appendages spinous in most species (with tubercles or carinae in Amphisternus ); maxillary lacinia without tuft of S-like setae at apex (present in Amphisternus ); intercoxal process of metaventrite subparallel-sided (widening in Amphisternus ) (after Tomaszewska 2005).

Biological notes.

Little is known about the ecology of Cacodaemon species. Adults can be collected from fungi growing on the underside of wood (Endo, personal communication).
