Determiner label Arenivaga floridensis Hopkins 2011" [white label with black border].

Distribution.

This species is found in central Florida. See Figure 56.

Diagnosis.

Arenivaga floridensis may be diagnosed by its locality or by the medially projecting knob by the posterior end of the point of articulation between the two right phallomeres. See Fig. 55.

Description.

Male. NB: Holotype is half spread therefore GW is estimated.Measurements. Holotype TL = 17.4 mm, GW = 9.0 mm, PW = 6.71 mm, PL = 4.26 mm, TL/GW = 1.93, PL/PW = 0.63. EW = 0.50 mm; OW = 0.55 mm. Among paratypes range of TL 13.8-20.7 mm; range of GW 7.7-10.7 mm; range of PW 5.43-7.24 mm; range of PL 3.82-4.69 mm.

Head. Two ocelli large, ovoid and protruding (0.40 × 0.30 mm); vertex dark brown, with small ridges between apices of eyes and scattered short setae; interocellar space concave, dark brown. Frons medium brown fading posteriorly to light brown, tectiform, concave; bound on either side by ridges extending from inner apex of ocelli outwards to lateral edges of clypeus; scattered long setae on ridges. Anterior portion of frons light brown with medium brown maculations, bulbous; clypeal suture demarcates light brown anteclypeus. See Fig. 54d.

Pronotum. Pronotum translucent waxy beige. Variable length orange-brown setae along anterior margin; dorsal surface of pronotum covered with short orange-brown setae; pronotal pattern "panther face" dark brown, with small to extensive aura depending on specimen; discernibility of detail variable but generally poor. See Fig. 54c.

Body. Wing brace present. Legs and body medium orange-brown; subgenital plate symmetrical with posterior edge emarginated, rounded apices. See Fig. 54b.

Forewings. Wings extended beyond abdominal apex (up to ~30% of total wing length); color uniform dark brown depending on specimen; surface opaque and matte, or with faint sheen on many specimens. See Fig. 54a.

Genitalia. Right dorsal phallomere composed of bulbous lightly sclerotized hook-shaped lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized; medial margin sclerotized, heavily toothed, curving ventrally at anterior end. Small central sclerite finely punctate, concave, with shagreened bulge along ventral edge. Right ventral phallomere extends from articulation into smooth flattened posteriorly projecting lobe with anteriorly projecting spine on medial edge; after ridge and moderate gap, rounded concave smooth flange. Folded anterior portion of left phallomere wide, setose, otherwise unmodified. Genital hook with pointed head with dimple along extension to a moderate hook. See Fig. 55.
