Embaphion glabrum Blaisdell, 1909

( Fig. 2A )

Diagnosis. Broadly elongate- oval, lateral margins of pronotum and lateral elytral carina acute and foliaceous (laminar and curled upward). Elytra glabrous, smooth without asperate punctures. Lateral elytral carina ends just before posterior elytral apex, although sometimes faintly traceable, never distinct as in E. contusum . Elytral apex acute, though males not tending towards caudate, as in E. contusum .

Distribution. Mohave, Coconino, Navajo, and Apache Counties, Arizona. New Mexico, Utah.

Remarks. This species strongly resembles E. contusum and can be separated from it by the elytral sculpturing and elytral margins. Embaphion glabrum can be found reliably in aeolian sand formations of the Arizona Strip, north of the Grand Canyon.
