Type locality.

MEXICO, Hidalgo, Zimapan.

Material examined.

Holotype: ♂ in EMEC labeled "Zimapan Hdgo. Mex. VI-11-14-51, on fls. of Eysenhardtia polystachya (Ort.), P.D.Hurd Collector" "HOLOTYPE Arenivaga florilega Hopkins, 2012" [red label with black border].

Paratypes: None at this time.

Etymology.

The name is an adjective in the nominative singular. This species is named from the Latin meaning flower gathering because the only known specimen was collected off the flowers of Eysenhardtia polystachya .

Distribution.

This species is known only from the type locality. See Fig. 59.

Diagnosis.

Arenivaga florilega may be confused with Arenivaga galeana but may be distinguished by the almost complete lack of sculpturing or sclerotization on the right dorsal phallomere, the posteriorly projecting lobe on the right ventral phallomere, and a round curved genital hook. See Figs 58 and 64.

Description.

Male.Measurements. Holotype TL = 19.7 mm, GW = 9.5 mm, PW = 5.37 mm, PL = 3.98 mm, TL/GW = 2.07, PL/PW = 0.74. EW = 0.15 mm; OW = 0.40 mm.

Head. Two ocelli large, ovoid and protruding (0.40 × 0.25 mm); vertex dark brown, with small ridges between apices of eyes and extending onto ocellar tubercles; interocellar space concave, dark brown. Frons dark medium brown; posterior concave; anterior portion of frons bulbous but much less so than in most species, dark medium brown; light brown anteclypeus. See Fig. 57d.

Pronotum. Pronotum translucent waxy light brown; dorsal surface of pronotum with dense orange-brown setae that are longer and thicker laterally; pronotal pattern dark orange-brown "panther face", impressed; slight aura. See Fig. 57c.

Body. Wing brace absent. Two tarsal claws present. Legs and body medium brown; subgenital plate orange-brown; strongly asymmetrical with posterior edge only slightly emarginated and rounded apices. See Fig. 57b.

Forewings. Wings extended beyond abdominal apex; light brown with sparse medium brown blotches; surface translucent with mild sheen. See Fig. 57a.

Genitalia. Right dorsal phallomere composed of lightly sclerotized, 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, concave with two punctate lobes wrapping anteriorly around shagreened flange of right dorsal phallomere, posterior end connecting with dorsal side of right dorsal phallomere. Articulation between right phallomeres deep, concave and setose, with shagreened border adjacent to dorsal phallomere and smooth border adjacent to ventral phallomere. Right ventral phallomere consists of large punctate flattened medially projecting lobe; becoming wider and more sclerotized anteriorly; anteriorly narrow gap followed by wide shagreened flange. Folded anterior portion of left phallomere wide, setose, otherwise unmodified. Genital hook widely curved to sharp point; arm robust and straight. See Fig. 58.
