Material examined
Holotype: > in USNM labeled “MEXICO: 3 mi. E. Galeana, N.L. 5000’, Aug. 7–9, 1963, Duckworth & Davis” “HOLOTYPE Arenivaga galeana Hopkins, 2012” [red label with black border].
Paratypes (11): MEXICO: Nuevo Leon, 6.4 km W Iturbide, 7/16/1979, 24.44N, 99.56W, 1800 m, DC Darling (1, CUIC); Nuevo Leon, 3 mi. E of Galeana, 8/7-9/1963, 5000 ft., Duckworth & Davis (8, USNM); El Salto Falls 26 mi. W of Antiguo Morelos, Tamps., 7/11-14/1963, 2000 ft., Duckworth & Davis (2, [one missing label] USNM). All paratypes labeled “Paratype Arenivaga galeana Hopkins 2012” [blue label with black border].
Etymology
The name is a noun in the genive case. This species is named for the Mexican town near where the majority of specimens originate, Galeana.
Distribution
This species occurs in the Sierra Madre Oriental mountains of eastern Mexico. See Fig. 65.
Diagnosis
Arenivaga galeana may be confused with Arenivaga florilega but may be distinguished by the right ventral phallomere which does not have a flattened, posteriorly projecting lobe as it does in Arenivaga florilega. Also the genital hook is the typical angular sort, not a sweeping curve as in Arenivaga florilega. See Figs 64 and 58.
Description
Male. Measurements. Holotype TL = 22.3 mm, GW = 9.8 mm, PW = 5.84 mm, PL = 3.79 mm, TL/GW = 2.28, PL/PW = 0.65. EW = 0.25 mm; OW = 0.40 mm. Among paratypes range of TL 19.6–23.5 mm; range of GW 8.4–9.8 mm; range of PW 5.38–6.22 mm; range of PL 3.73–4.33 mm.
Head. Two ocelli large, ovoid and protruding (0.50 ? 0.30 mm); vertex dark brown, with small ridges between apices of eyes and extending onto ocellar tubercles; interocellar space concave, dark brown. Frons dark brown; posterior concave; anterior portion of frons slightly bulbous, anterior margin with medial point, medium brown; light brown anteclypeus. See Fig. 63d.
Pronotum. Pronotum translucent waxy beige; dorsal surface of pronotum with short orange-brown setae that are longer and thicker laterally; pronotal pattern dark orange-brown “panther face”, impressed, with medium orange-brown aura. See Fig. 63c.
Body. Wing brace absent. Two tarsal claws present. Legs and body light brown; subgenital plate dark orange-brown; strongly asymmetrical with rounded apices. See Fig. 63b.
Forewings. Wings extended beyond abdominal apex (up to 40% of total wing length); blotchy medium brown; surface translucent with mild sheen. See Fig. 63a.
Genitalia. Right dorsal phallomere composed of lightly sclerotized, 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 knob. Small central sclerite lightly sclerotized, finely punctate, concave with two punctate lobes wrapping anteriorly around shagreened knob 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 faint smooth border adjacent to ventral phallomere; shagreened border coming to posteriorly projecting pointed extension. Right ventral phallomere consists of large punctate flattened medially projecting lobe with central indentation; becoming wider and more sclerotized anteriorly; anteriorly wide gap followed by wide shagreened flange with slight central concavity. Folded anterior portion of left phallomere wide, setose, enclosed at both ends with indentation at medial end, otherwise unmodified. Genital hook with short extension to pointed head and short hook; arm robust. See Fig. 64.
Habitat and natural history
All life history elements remain unobserved.
