Paratypes (3): MEXICO: Sonora, Obregon, 7/29/1952, C & P Vaurie (2, AMNH); Sonora, Ciudad Obregon, 8/9/1960, WW Gibson, at light (1, UAIC). All paratypes labeled "Paratype Arenivaga hebardi Hopkins 2012" [blue label with black border].

Etymology.

The name is a noun in the genitive case. This species is named for the great Orthoptera researcher of the early 20th century and last reviser of this genus, Morgan Hebard.

Distribution.

This species is found in and around Ciudad Obregon, Sonora, Mexico. See Fig. 86.

Diagnosis.

Arenivaga hebardi may be distinguished by the robust double hook at the posterior and of the medial margin of the right dorsal phallomere. See Fig. 85.

Description.

Male.Measurements. Holotype TL = 17.7 mm, GW = 8.4 mm, PW = 5.94 mm, PL = 4.22 mm, TL/GW = 2.11, PL/PW = 0.71. EW = 0.15 mm; OW = 0.30 mm. No notable size variation among paratypes.

Head. Two ocelli large, ovoid and protruding (0.50 × 0.40 mm); vertex medium brown, with small ridges between apices of eyes and extending onto ocellar tubercles; interocellar space concave, medium brown, with arrowhead-shaped indentation. Frons light brown; posterior concave, with shallow horizontal corrugations; anterior portion of frons bulbous, light brown; wide light brown anteclypeus with medial point. See Fig. 84d.

Pronotum. Pronotum translucent waxy beige; dorsal surface of pronotum with dense very short light orange-brown setae; pronotal pattern medium orange-brown "hippo face" with some discernible detail; no aura. See Fig. 84c.

Body. Wing brace present. Two tarsal claws present. Legs and body light orange-brown; subgenital plate light orange-brown with darker border; asymmetrical with rounded apices. See Fig. 84b.

Forewings. Wings extended well beyond abdominal apex (up to ~30% of wing length); blotchy medium orange-brown; surface matte and opaque. See Fig. 84a.

Genitalia. Right dorsal phallomere composed of lightly sclerotized, broad bulbous lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized, slightly cupped; medial edge more sclerotized, smooth, with robust posteriorly projecting spine and immediately adjacent medially projecting smaller spine. Small central sclerite lightly sclerotized, finely punctate, concave, anterior end with smooth posteriorly projecting ridge; smooth flat point at dorsal end of ridge with one or two very small spines along rest of ridge. Right ventral phallomere arises from articulation to form large punctate rounded lobe, becoming more sclerotized, corrugated, shagreened and narrow anteriorly; small shagreened fold in moderate gap followed by wide dorsally flanged, concave arm, smooth to punctate, extending to slightly greater depth than rest of phallomere. Folded anterior portion of left phallomere narrow and setose, otherwise unmodified. Genital hook with short extension to pointed head; short hook; arm delicate with distinct bend. See Fig. 85.
