Etymology.

The name is an adjective in the nominative singular. This species is named from the Greek meaning dark, gloomy or murky because of its very dark color.

Distribution.

This species is found in the state of Puebla, Mexico. See Fig. 47.

Diagnosis.

Arenivaga dnopheros is very similar to Arenivaga aquila . Arenivaga dnopheros has larger projection on the left phallomere than Arenivaga aquila . The anterior arm of the right ventral phallomere is also much more shagreened with pronounced central indentation. These two characters may be used to distinguish Arenivaga dnopheros . See Figs 46 and 28.

Description.

Male.Measurements. Holotype TL = 21.9 mm, GW = 9.6 mm, PW = 6.34 mm, PL = 4.38 mm, TL/GW = 2.28, PL/PW = 0.69. EW = 0.25 mm; OW = 0.60 mm. Among paratypes range of TL 18.5-22.0 mm; range of GW 8.4-10.0 mm; range of PW 5.20-6.70 mm; range of PL 3.62-4.45 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 deeply concave, dark to medium brown, with <> shaped indentations. Frons medium brown; posterior concave but tectiform horizontally; anterior portion of frons bulbous but much less so than in most species, medium brown; narrow light brown anteclypeus. See Fig. 45d.

Pronotum. Pronotum with translucent waxy beige anterior margin; remainder of pronotum very dark orange-brown and dark brown; dorsal surface of pronotum with dense short orange-brown setae; pronotal pattern "panther face", impressed; extensive dark aura. See Fig. 45c.

Body. Wing brace absent. Two tarsal claws present. Legs and body medium orange-brown; subgenital plate orange-brown; strongly asymmetrical with posterior edge only slightly emarginated and rounded apices. See Fig. 45b.

Forewings. Wings extended well beyond abdominal apex (up to ~40% of wing length); blotchy dark brown; surface matte or with very slight sheen and opaque. See Fig. 45a.

Genitalia. Right dorsal phallomere composed of lightly sclerotized, narrow bulbous lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized, slightly cupped; with narrow medial edge more sclerotized, punctate, ending anteriorly in small shagreened knob. Small central sclerite lightly sclerotized, finely punctate, flat of nondescript shape, posterior end connecting with dorsal side of right dorsal phallomere. Right ventral phallomere arises from deep articulation to form large punctate lobe; anteriorly moderate gap followed by two dorsally projecting sclerotized heavily toothed folds. Folded anterior portion of left phallomere wide, setose, closed at both ends, with small nipple at one end of fold, rough-edged, flattened projection offset at an angle from other end. Genital hook with short extension to rounded head; short hook; arm robust. See Fig. 46.
