see text Dinacoma is a small genus of beetles in the scarab family (Scarabaeidae).

In 2006, entomologists indicated that there were two apparently new species or subspecies of Dinacoma, collected respectively from near the city of Hemet, California, and in the northwest portion of Joshua Tree National Park, California, at Covington Flats.

[2] La Rue (2006, p. 2) stated that Dinacoma caseyi is the most morphologically divergent and distinct species in the genus.
