Etymology.

The name is a noun in the genitive case. This species is named in honor and fond remembrance of Douglas Adams, whose writing makes me laugh, and who loved and respected all life on this planet.

Distribution.

This species is found in central Sonora and northern Sinaloa Mexico and southeastern Arizona. See Fig. 14.

Diagnosis.

Arenivaga adamsi may be confused with Arenivaga moctezuma but can be distinguished by the single large spine on the posterior end of the medial margin of the right dorsal phallomere. See Figs 11 and 104.

Description.

Male.Measurements. Holotype TL = 17.5 mm, GW = 9.0 mm, PW = 6.13 mm, PL = 4.33 mm, TL/GW = 1.94, PL/PW = 0.71. EW = 0.30 mm; OW = 0.30 mm. Among paratypes range of TL 15.8-20.7 mm; range of GW 7.3-10.3 mm; range of PW 5.47-6.33 mm; range of PL 3.60-4.57 mm.

Head. Two ocelli large, ovoid and protruding (0.40 × 0.30 mm); vertex dark brown with small ridges in rays around upper apices of eyes and extending onto ocellar tubercles; interocellar space concave, medium brown. Frons translucent peach-brown, unusually wide, posterior concave; anterior portion of frons bulbous and translucent peach-brown; translucent peach-brown smooth anteclypeus. See Fig. 12d.

Pronotum. Pronotum translucent waxy beige; dorsal surface of pronotum with short orange-brown setae that are thicker and longer laterally; pronotal pattern orange-brown or red-brown "panther face", with scattered maculations of same color as pattern; discernible detail within pattern variable; slight aura. See Fig. 12c.

Body. Wing brace present. Two tarsal claws present. Legs and body light orange-brown; many specimens with brown maculations laterally on each sternite; subgenital plate light orange-brown; asymmetrical with rounded apices. See Fig. 12b.

Forewings. Wings extended well beyond abdominal apex (up to 40% of wing length); blotchy medium to dark brown depending on specimen; surface matte and opaque. See Fig. 12a.

Genitalia. Right dorsal phallomere composed of lightly sclerotized, long, bulbous hook-shaped lobe, articulated with right ventral phallomere on lateral side; medial side of lobe deeply emarginated from medial edge of remainder of phallomere; central field shallow, cupped, lightly sclerotized; medial margin more heavily sclerotized, smooth, with long posterior projecting spine. Small central sclerite punctate, with large shagreened, rugose, medially projecting bilobed bulge; right ventral phallomere extends from articulation to form shagreened rounded structure, with prominent medially projecting spine located posteriorly; attached anteriorly is mildly dorsally projecting flanged smooth concave arm, that extends only slightly beyond depth of rest of phallomere, apex punctate. Folded anterior portion of left phallomere dramatically modified with sclerotized anterior wall and posteriorly projecting setose spine located ventrally. Genital hook with short extension to pointed head with moderate hook; arm smoothly curved. See Fig. 13.
