Recognition. This species is characterized by fronto-orbital setae weak; antenna dark; Face mostly shiny, with thin pruinescence restricted to antennal foveae; parafacial shiny; fore coxa and all femora dark; hind femur without anteroventral preapical setae; surstylus digitiform, strongly tapered to rounded apex.

Description. Frons dark to somewhat reddish-brown above antennae; gena dark. Face mostly shiny, with thin pruinescence restricted to antennal foveae; parafacial shiny. Fronto-orbital setae weak. Antenna entirely dark ( Fig. 14View FIGURES 11–14); antennal bases separated by more than length of pedicel. Clypeus shiny.

Katepisternum with several stout ventral setae, anterior to mid coxa; short setulae on anterior half. Scutum shiny with sparse setulae. Coxae and femora dark, with apex of femora pale; mid and hind tibiae darkened in middle, pale basally and apically; fore tibia mostly pale; tarsomeres on all legs pale; mid tibia with dark ventroapical seta, more than one-quarter length of tarsomere 1.

Male postabdomen ( Fig. 45View FIGURES 45–48): epandrium rounded, evenly sclerotized, setose. Hypandrium broad, with pair of long anterior setae; with rounded postgonite apically. Surstylus digitiform, strongly tapered to rounded apex; apex arch posteromedially; setae confined mostly to posterior margin. Distiphallus tapered to narrow apex. Cercus elongate, longer than dorsal length of epandrium; apex narrow; ventral margin sclerotized.

Female postabdomen: undissected.

Distribution. This species is known from the southern border of Arizona and Chihuahua of Mexico ( Fig. 50View FIGURES 49–50).
