Coelocnemis
darkling beetles, broad-necked darkling beetles
Coelocnemis is a genus of darkling beetles in the family Tenebrionidae, containing approximately seven described species distributed across western North America. These large, flightless beetles are primarily associated with coniferous forest habitats, particularly pine and oak-conifer woodlands, where they are active nocturnally. The genus is distinguished from superficially similar darkling beetles by distinctive morphological features, including parallel lines of yellow pubescence on the inner tibial surfaces.
Coelocnemis rugulosa
Coelocnemis rugulosa is a species of darkling beetle in the family Tenebrionidae, described by Doyen in 1973. It belongs to a genus of seven species found in western North America and adjacent southern Canada. Like other Coelocnemis species, it is a flightless, nocturnal beetle adapted to xeric forest habitats. The genus is distinguished from the superficially similar Eleodes by having distinct parallel lines of yellow pubescence on the inner surface of the tibiae.
