Etymology.

The name is an adjective in the nominative singular. This species is named from the Latin meaning dark-colored or swarthy because of its very dark color.

Distribution.

This species is found in the states of Morelos and Guerrero, Mexico. See Fig. 29.

Diagnosis.

Arenivaga aquila may be distinguished by the small ridge projecting from the ventrolateral edge of the folded portion of the left phallomere. See Fig. 28.

Description.

Male.Measurements. Holotype TL = 19.1 mm, GW = 8.4 mm, PW = 6.00 mm, PL = 4.17 mm, TL/GW = 2.27, PL/PW = 0.70. EW = 0.15 mm; OW = 0.40 mm. Among paratypes range of TL 18.0-21.5 mm; range of GW 8.2-10.1 mm; range of PW 5.60-6.74 mm; range of PL 3.94-4.59 mm.

Head. Two ocelli large, ovoid and protruding (0.40 × 0.30 mm); vertex dark brown, with small ridges between apices of eyes and extending onto ocellar tubercles; interocellar space concave, dark brown, with two small oval indentations. Frons light brown; posterior concave; anterior portion of frons bulbous but much less so than in most species, light brown; light brown anteclypeus. See Fig. 27d.

Pronotum. Pronotum with translucent waxy beige anterior margin; aura so extensive that remainder of pronotum dark orange-brown and dark brown; pronotal pattern impressed "panther face", difficult to discern. See Fig. 27c.

Body. Wing brace absent. Legs and body medium orange-brown; subgenital plate orange-brown; strongly asymmetrical with angular apices. See Fig. 27b.

Forewings. Wings extended well beyond abdominal apex (up to ~40% of wing length); blotchy dark brown to solid dark brown depending on specimen; surface matte and opaque. See Fig. 27a.

Genitalia. Right dorsal phallomere composed of lightly sclerotized, short, narrow, bulbous lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized, cupped; with narrow medial edge more sclerotized, punctate, ending anteriorly in small shagreened flange. Small central sclerite lightly sclerotized, finely punctate, flat of no discernible shape, posterior end connecting with dorsal side of right dorsal phallomere. Right ventral phallomere arises from deep articulation to form large punctate flattened medially projecting lobe; becoming wider and more sclerotized anteriorly; after narrow gap, wide shagreened flange. Folded anterior portion of left phallomere wide, setose, closed at both ends, with small nipple at one end of fold, and rough-edged, flattened projection offset at an angle from other end. Genital hook with short extension to rounded head and short hook; arm robust and smoothly curving. See Fig. 28.
