Etymology.

The name is an adjective in the nominative singular. This species is named gaiophanes for its beautiful uniform earth tone coloration, from Greek meaning “earth-colored”.

Distribution.

This species is distributed from Lake Arrowhead in the north, to Wildcat Canyon in the south, and from Hemet in the east, to San Juan Creek in the west. See Figure 62.

Diagnosis.

Arenivaga gaiophanes sp. n. is slightly smaller than average, warm brown in color with scattered blotches. It can be mistaken phenotypically for Arenivaga sequoia but the genitalia are distinct; the medial margin of the right dorsal phallomere is deeply indented in Arenivaga gaiophanes but not at all in Arenivaga sequoia . See Figs 61 and 142.

Description.

Male.Measurements. Holotype TL = 19.2 mm, GW = 9.2 mm, PW = 5.22 mm, PL = 3.81 mm, TL/GW = 2.09, PL/PW = 0.73. EW = 0.3 mm; OW = 0.4 mm. Among paratypes range of TL 15.6-19.2 mm; range of GW 7.5-9.2 mm; range of PW 5.02-6.00 mm; range of PL 2.97-4.24 mm.

Head. Two ocelli large, ovoid and protruding (0.45 × 0.35 mm); vertex medium brown with small ridges in rays around upper apices of eyes and extending onto ocellar tubercles; interocellar space concave, rugose, medium brown. Posterior frons light brown, concave; anterior frons bulbous with slight central indentation; light brown anteclypeus. See Fig. 60d.

Pronotum. Pronotum translucent, waxy beige; dorsal surface of pronotum with short fine brown setae centrally and posteriorly grading to longer, thicker setae laterally and anteriorly; pronotal pattern brown "panther face"; brown maculations scattered across posterior 70% of dorsal surface of pronotum; no aura. See Fig. 60c.

Body. Wing brace present. Two tarsal claws present. Legs and body light orange-brown; darker maculation laterally on each sternite; subgenital plate dark orange-brown; strongly asymmetrical with rounded apices. See Fig. 60b.

Forewings. Wings extended well beyond abdominal apex (~40% of wing length); color uniform brown, to blotchy brown; surface matte and opaque. See Fig. 60a.

Genitalia. Right dorsal phallomere composed of bulbous lightly sclerotized hook-shaped lobe, articulated with right ventral phallomere on lateral side; central field sclerotized; medial margin with deep V-shaped emargination projecting to two broad flat points; entire phallomere shagreened except hook-shaped lobe and anterior point; entire medial margin with short teeth; interior of lateral articulation setose; broad rolled sclerotized lip projecting posteriorly from lateral articulation. Small central sclerite broad, flat and finely punctate with posteriorly projecting, sclerotized lip at anterior end; right ventral phallomere extends from articulation to form rounded shagreened structure with fine corrugations; attached anteriorly is mildly dorsally projecting flanged forked arm, shagreened with roughly toothed edge. Folded anterior portion of left phallomere setose, otherwise unmodified. Genital hook with short extension to pointed head with short hook; arm robust. See Fig. 61.

Habitat and natural history.

This species occurs in hilly or mountainous habitat. All other life history elements remain unobserved.
