coalitus group

The members of this species group are relatively large clerids (6.0–10.0 mm) whose pubescent pattern does not conform to the typical pattern as seen in the fronticepiece. In these beetles, there is an admixture of dark and pale setae on the elytral disc. The pale setae may or may not be organized in narrow lines or oblique patches. The presence of asetiferous punctations, particularly prominent in the posthumeral regions, is an apomorphic characteristic for this group of species. Further, the secondary elytral setae are not concentrated into transverse tufts at the middle of the elytra. The combined known range of this species group extends from the Oaxacan highlands of Mexico to the lower elevations of central Costa Rica.
