Eleodes (Tricheleodes) barbatus Wickham, 1918

( Fig. 5A )

Diagnosis. Body small, broadly oval, heavily punctate and clothed in long, golden setae. Pronotum rounded, with large punctures medially, each with a single, long seta. Elytra quite rounded and rugose, with rows of large punctures separating tubercles which each produce a single seta.

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

Remarks. This distinctive species is the smallest of the Arizona fauna and only rivaled in size by several of the coastal species in California. It can be found in aeolian sand formations in the Four Corners region. Its relative scarcity in collections and patchy distribution are likely due to limited collecting in the deserts of this region.
