Etymology.

The name is a noun in the genitive case. This species is named in honor of Donald Harington, author of "The Cockroaches of Stay More", a priceless novel about wonderful animals.

Distribution.

This species is found in west central Arizona and southeastern Nevada. See Fig. 83.

Diagnosis.

Arenivaga haringtoni may be distinguished by its dark brown color as it is the only species of its color found in its range. If locality information is not available it may be distinguished by the long medial margin on the right dorsal phallomere, which extends posteriorly some distance beyond the rest of the phallomere. See Fig. 82.

Description.

Male.Measurements. Holotype TL = 17.6 mm, GW = 8.7 mm, PW = 5.82 mm, PL = 4.04 mm, TL/GW = 2.02, PL/PW = 0.69. EW = 0.65 mm; OW = 0.45 mm. Among paratypes range of TL 16.9-18.3 mm; range of GW 7.6-10.7 mm; range of PW 5.33-6.28 mm; range of PL 4.04-4.45 mm.

Head. Two ocelli large, ovoid and protruding (0.35 × 0.25 mm); vertex dark brown with small ridges in rays around upper apices of eyes and extending onto ocellar tubercles; pale medial line; interocellar space concave, dark brown, light brown medially, with two oval indentations. Frons translucent beige, posterior concave; anterior portion of frons bulbous and translucent beige; translucent beige smooth anteclypeus. See Fig. 81d.

Pronotum. Pronotum translucent, waxy beige; dorsal surface of pronotum with short orange-brown setae that are thicker and longer laterally; pronotal pattern dark brown to red-brown "panther face", with some discernible detail and extensive aura, generally on all sides. See Fig. 81c.

Body. Wing brace present. Two tarsal claws present. Legs and body light brown; sternites medium brown laterally; subgenital plate light brown with darker posterior edge; asymmetrical with rounded apices. See Fig. 81b.

Forewings. Wings extended well beyond abdominal apex (~40% of wing length); color varies from uniform medium brown to blotchy medium brown; surface may be matte and opaque or translucent and lustrous. See Fig. 81a.

Genitalia. Right dorsal phallomere composed of lightly sclerotized bulbous lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized; medial margin more heavily sclerotized, shagreened with rough edge, very slightly arcuate centrally. Small central sclerite nearly flat, nondescript in shape, finely punctate, rugose anteriorly; right ventral phallomere extends from articulation to form smooth rounded structure becoming punctate and corrugated anteriorly; attached anteriorly is mildly dorsally projecting flanged concave punctate arm that extends beyond depth of rest of phallomere, exterior surface shagreened. Folded anterior portion of left phallomere setose and punctate, otherwise unmodified. Genital hook with long extension to pointed head, and slight indentation on moderate hook; distinct bend in arm. See Fig. 82.
