Etymology.

This species is named from the Latin meaning "from lichen" because the holotype was taken from lichen.

Distribution.

This species is found in western and north-central Baja California Norte, Mexico. See Fig. 20.

Diagnosis.

Arenivaga alichenas may be diagnosed by very narrow hook-shaped lobe on the right dorsal phallomere and the sclerotized edge of the anterior portion of the small central sclerite. See Fig. 19.

Description.

Male.Measurements. Holotype TL = 14.3 mm, GW = 7.2 mm, PW = 5.00 mm, PL = 3.55 mm, TL/GW = 1.97, PL/PW = 0.71. EW = 0.70 mm; OW = 0.45 mm. No notable difference in measurements among paratypes.

Head. Two ocelli large, ovoid and protruding (0.30 × 0.20 mm); vertex medium brown, with small ridges in rays around upper apices of eyes and extending onto ocellar tubercles; interocellar space deeply concave, medium brown, lighter medially. Frons waxy white, concave; anterior portion of frons waxy white, bulbous; light brown anteclypeus. See Fig. 18d.

Pronotum. Pronotum small; translucent waxy beige with fine dark brown margin; dorsal surface of pronotum covered with dense golden brown setae, could be called furry; pronotal pattern dark orange-brown "panther face" with medium to dark brown aura; detail impressed. See Fig. 18c.

Body. Wing brace present. Legs and body light brown; subgenital plate dissected and cleared with angular apices. See Fig. 18b.

Forewings. Wings extended beyond abdominal apex (up to ~30% of total wing length); no blotchiness, medium to dark brown; surface translucent, with slight sheen. See Fig. 18a.

Genitalia. Right dorsal phallomere composed of bulbous lightly sclerotized narrow hook-shaped lobe, articulated with right ventral phallomere on lateral side; central field broad, lightly sclerotized, punctate; medial margin heavily sclerotized, shagreened with straight toothed edge. Small central sclerite concave, with punctate crescent shape with more sclerotized margins anteriorly; anterior rounded point curves back on itself; posterior margin attached to dorsal side of right dorsal phallomere. Right ventral phallomere extends from articulation to form flattened smooth lobe, increasingly punctate and sclerotized anteriorly; after narrow gap, wide rounded concave shagreened arm extending to depth of rest of phallomere. Folded anterior portion of left phallomere narrow, setose, otherwise unmodified. Genital hook with long extension to pointed head with slight concavity on short hook; arm smoothly curved. See Fig. 19.
