Embaphion depressum (LeConte, 1851)

( Fig. 1C )

Eleodes depressus LeConte, 1851

Diagnosis. Elongate oval, smallest species of the genus (<13 mm). Pronotum and elytra acute laterally, but not foliaceous as in the other species. Pronotum densely punctured, punctures large.

Distribution. Maricopa and Yuma Counties, Arizona. Southern California.

Remarks. This small species is uncommonly collected in Arizona, although it can be fairly abundant in the aeolian sand formations found between Agua Caliente, Dateland, and Yuma. This is the only known species of Embaphion to not have the pronotal margins upturned, and this is likely why LeConte (1851) originally opted to place it in Eleodes .
