Male. Measurements. Holotype TL = 18.3 mm, GW = 9.2 mm, PW = 6.10 mm, PL = 4.07 mm, TL/GW = 1.99, PL/PW = 0.67. EW = 0.30 mm; OW = 0.40 mm. Among paratypes range of TL 15.5–22.3 mm; range of GW 7.6–10.3 mm; range of PW 5.25–6.63 mm; range of PL 3.85–4.49 mm. Head. Two ocelli large, ovoid and protruding (0.40 × 0.30 mm); vertex dark brown with small ridges in rays around upper apex of eyes and extending onto ocellar tubercles; interocellar space concave, dark brown, lighter brown anteriorly, with horizontal indentation. Frons waxy white, posterior concave; anterior portion of frons bulbous and waxy white; waxy white smooth anteclypeus. See Fig. 87d. Pronotum. Pronotum opaque, light brown; dorsal surface of pronotum with short orange-brown setae that are thicker and longer laterally; pronotal pattern dark brown “panther face”, in some specimens so dark as to obscure detail; slight lateral and anterior aura. See Fig. 87c. Body. Wing brace present. Two tarsal claws present. Legs and body light brown; sternites of many specimens with fine brown line and brown maculations laterally; subgenital plate light brown; asymmetrical with particularly deep central emargination and angular apices. See Fig. 87b. Forewings. Wings extended well beyond abdominal apex (up to 50% of wing length); blotchy medium to dark brown depending on specimen; surface matte and opaque. See Fig. 87a. Genitalia. Right dorsal phallomere composed of lightly sclerotized bulbous hook-shaped lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized; medial margin more heavily sclerotized, narrow with two prominent spines. Small central sclerite deeply concave, punctate, with two sclerotized, punctate lobes on ventral wall; right ventral phallomere extends from articulation to form smooth rounded structure, punctate, with prominent medially projecting spine located posteriorly; attached anteriorly and at an acute angle is mildly dorsally projecting narrowly flanged concave punctate arm that extends beyond depth of rest of phallomere. Folded anterior portion of left phallomere dramatically modified with sclerotized anterior wall and posteriorly projecting spine located ventrally. Genital hook with moderate extension to pointed head with short hook; arm smoothly curving. See Fig. 88.

This species is found in northwestern Sonora, Mexico and southeastern and south central Arizona. The lone specimen from southern California is believed to have an incorrect label or carried there by an outside agent. See Fig. 89.
