Etymology
The name is an adjective in the nominative singular. This species is named from the Latin meaning tenacious.
Distribution
This species is found in New Mexico, far northwestern Texas, far southeastern Arizona, and neighboring parts of Mexico. See Fig. 146.
Diagnosis
Arenivaga tenax can be distinguished by the small medial spine on the medial margin of the right dorsal phallomere and the toothed distal end of that margin. See Fig. 145.
Description
Male. Measurements. Holotype TL = 19.2 mm, GW = 8.1 mm, PW = 5.22 mm, PL = 3.89 mm, TL/GW = 2.37, PL/PW = 0.75. EW = 0.20 mm; OW = 0.30 mm. Among paratypes range of TL 19.2–21.7 mm; range of GW 7.8–10.0 mm; range of PW 5.22–6.61 mm; range of PL 3.89–4.33 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, dark brown, with three small round indentations at points of an equilateral triangle. Posterior frons dark brown grading into waxy white; concave, smooth with anterior portion of frons bulbous and waxy white; waxy white smooth anteclypeus. See Fig. 144d.
Pronotum. Pronotum translucent waxy beige; dorsal surface of pronotum with short orange-brown setae that are thicker and longer laterally; pronotal pattern brown “panther face” with some discernible detail; no aura. See Fig. 144c.
Body. Wing brace present. Two tarsal claws present. Legs and body light brown, many specimens with brown maculations laterally on each sternite; subgenital plate light brown; asymmetrical with angular apices. See Fig. 144b.
Forewings. Wings extended well beyond abdominal apex (~40% of wing length); blotchy medium brown; surface opaque and matte or with very slight sheen. See Fig. 144a.
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, with short toothed region at posterior end, and short flat spine medially, otherwise smooth. Small central sclerite nearly flat and finely punctate, with raised sinuous line of teeth at lateral edge; right ventral phallomere extends from articulation to form smooth rounded structure, shagreened, corrugated and narrowed anteriorly; attached anteriorly is mildly dorsally projecting flanged concave punctate arm, with shagreened edge, that extends to depth of posterior portion of phallomere. Folded anterior portion of left phallomere setose, otherwise unmodified. Genital hook with moderate extension to pointed head with moderate hook; arm with smooth shallow curve. See Fig. 145.
Habitat and natural history
All life history elements remain unobserved.
