Arenivaga belli (лат.) — вид песчаных тараканов-черепашек рода Arenivaga из семейства Corydiidae (или Polyphagidae). Обнаружены в Северной Америке: США (Калифорния, Невада, Юта).

Male. Measurements. Holotype TL = 19.2 mm, GW = 9.4 mm, PW = 5.47 mm, PL = 3.66 mm, TL/GW = 2.04, PL/PW = 0.67. EW = 0.2 mm; OW = 0.3 mm. Among paratypes range of TL 17.7–21.2 mm; range of GW 7.6–9.4 mm; range of PW 5.32–6.38 mm; range of PL 3.66–4.33 mm. Head. Two ocelli large, ovoid and protruding (0.40 × 0.30 mm); vertex medium brown with small ridges in rays around upper apices of eyes and extending onto ocellar tubercles; interocellar space concave, medium brown, with two deep set dimples medial to inner apex of ocelli; with two smaller dimples anterior to those which may be very hard to see; rugose in some specimens. Frons light brown fading to waxy white towards margin with clypeus; concave with small vertical corrugations. Clypeus waxy white and bulbous; ends in broad flat anteclypeus of same color. See Fig. 30d. Pronotum: Pronotum translucent, waxy beige; dorsal surface of pronotum with short fine orange-brown setae centrally and posteriorly grading to longer, thicker setae laterally and anteriorly; pronotal pattern orange-brown “panther face” with little discernible detail in most specimens; no aura. See Fig. 30c. Body. Wing brace present. Legs and body light orange-brown, subgenital plate with darker margin, strongly asymmetrical with rounded apices. See Fig. 30b. Forewings. Wings extended well beyond abdominal apex (~40% of wing length); color uniform brown, to blotchy brown; surface matte and opaque. See Fig. 30a. Genitalia. Right dorsal phallomere composed of bulbous lightly sclerotized hook-shaped lobe, articulated with right ventral phallomere on lateral side; central field broad, lightly sclerotized; medial margin heavily sclerotized, shagreened, with toothed edge extending into short spine near distal end. Small central sclerite flat and finely punctate with posteriorly projecting, shagreened crescent with elevated and toothed arms; right ventral phallomere extends from articulation to form rounded punctate structure at posterior apex but with shagreened corrugations at anterior apical end, followed by smaller offset shagreened projection, narrow gap, and rounded concave angled arm extending beyond depth of rest of phallomere. Folded anterior portion of left phallomere setose, otherwise unmodified. Genital hook with long extension to pointed head with slight concavity on short hook; arm smoothly curved. See Fig. 31.

This species is distributed from Lone Pine, CA in the west to Hanksville, UT in the north and east, and the Rice Dunes in the south. See Fig. 32.
