Distribution.

This species is found in southeastern Arizona, with scattered records extending south into and across Mexico to the west side of the Sierra Madre Oriental, and an isolated record from far southern Texas. See Fig. 74.

Diagnosis.

Arenivaga grata may be confused phenotypically with Arenivaga bolliana but their distributions are distinct. If locality information is not available Arenivaga grata may be diagnosed by the unusual shape of the hook-shaped lobe and the prominent shagreened ridge running interior to the point of articulation, both on the right dorsal phallomere. See Fig. 73.

Description.

Male.Measurements. Holotype stand-in TL = 26.8 mm, GW = 11.5 mm, PW = 7.55 mm, PL = 5.16 mm, TL/GW = 2.33, PL/PW = 0.68. EW = 0.40 mm; OW = 0.70 mm. Among paratypes range of TL 21.4-29.2 mm; range of GW 9.5-12.8 mm; range of PW 6.36-8.35 mm; range of PL 4.22-5.38 mm.

Head. Two ocelli large, ovoid and protruding (0.50 × 0.40 mm); vertex dark brown, with small ridges between apices of eyes extending on to ocellar tubercles, scattered short setae; interocellar space concave, medium to light brown; two round medium brown indentations laterally at the base of the interocellar space. Frons light brown, slightly concave; bound on either side by ridges extending from inner apex of ocelli outwards to lateral edges of clypeus; scattered setae on ridges. Anterior portion of frons light brown, bulbous; clypeal suture demarcates light brown anteclypeus. See Fig. 72d.

Pronotum. Pronotum with translucent waxy beige anterior margin; variable length orange-brown setae along anterior margin; dorsal surface of pronotum covered with short orange-brown setae; pronotal pattern medium orange-brown "panther face", with little detail and complete lateral and posterior aura in light orange-brown; pronotal pattern runs from light orange-brown to dark brown in other specimens, pattern always little discernible, aura always complete laterally and posteriorly. See Fig. 72c.

Body. Wing brace absent. Legs and body medium orange-brown; subgenital plate asymmetrical with posterior edge only slightly emarginated, rounded apices. See Fig. 72b.

Forewings. Wings extended beyond abdominal apex (up to ~35% of total wing length); medium orange-brown with darker blotches; color variable in species from medium orange-brown, to medium and dark brown, always blotchy; surface opaque and matte. See Fig. 72a.

Genitalia. Right dorsal phallomere composed of slightly bulbous lightly sclerotized narrow ended hook-shaped lobe with little to no curve to hook, articulated with right ventral phallomere on lateral side; central field lightly sclerotized; medial margin straight and contiguous with medial edge of hook-shaped lobe, lightly sclerotized, smooth, with no sculpturing of any kind. Small central sclerite nondescript in shape, flat, finely punctate. Right ventral phallomere extends from articulation into posterior pointing punctate lobe with small dorsal projection on posterior end; after moderate gap, broad, punctate flange with shagreened emarginate edge, extending to depth of rest of phallomere. Genital hook with broad pointed head and moderate hook with bent tip; arm broad and smoothly curving. See Fig. 73.
