( Figs. 272 , 407 , Map 51)

Diagnosis.— Hypatopa gena can be distinguished from other Hypatopa by having a grayish-brown ground color to the forewing with faint markings.

Description.—Head: Scales on vertex and frontoclypeus grayish-brown tipped with pale grayish brown. Outer and inner surfaces of labial palpus brown intermixed with few pale-brown scales along apical margins of segments 1–2. Antennal scape grayish brown intermixed with few pale grayish-brown scales, pecten pale grayish brown, flagellum brownish gray basally gradually brightening apically. Proboscis pale brown.

Thorax: Tegula and mesonotum agouti patterned, grayish brown on basal and apical 1/3s, pale brown on middle 1/3. Legs brown intermixed with grayish-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 407 ): Length 7.1–7.5 mm (n = 2), grayish brown intermixed with few brown scales; submedian fascia complete, faint; cell with three brown spots, one near middle, two on apical end along crossvein; marginal spots faint. Undersurface brown. Hindwing: Translucent pale brown gradually darkening to apex.

Abdomen: Male genitalia: Unknown. Female Genitalia ( Fig. 272 ): Apophyses posteriores 2X longer than apophyses anteriores. Eighth tergum with darkly pigmented median longitudinal streak. Ostium bursae within sparsely microtrichiate membrane posterior to seventh segment; inception of ductus seminalis at base of slightly dilated antrum equidistant between posterior and anterior margins of seventh sternum; Posterior margin of seventh sternum broadly emarginate laterally and mesially, forming two rounded lobes anterior to Ostium bursae.
