Dorsal body setae reaching about to or to the bases of setae of next row; setae subequal in length, strong, serrate, parallel sided, and tapering to point distally. Striae with broad lobes, longitudinal between DC3 and V-like posterior to DC4. Ventral body setae normal and slender. Length of body 363μ, including rostrum 447μ.

This species is similar to Mononychellus siccus (Pritchard and Baker), which was collected from a leguminous shrub at Phoenix, Arizona. It differs in that the setae are shorter and much stouter, and that the head of the aedeagus of M. siccus appears to be rounded or knoblike.
