( Figs. 10 , 77–78 , 255 , 282 , 325 , Map 8)

Diagnosis.— Blastobasis deae is similar to B. erae in facies but differs from the latter by having a wider uncus; a narrower gnathos; a more inwardly curved digitate process of the dorsal part of the valva; and a narrower proximal flange of the dorsal part of the valva. B. deae also has a an anteriorly directed posteroventral margin of the gnathos; a bulbous base of the phallus; a sigmoid-shaped sclerite of the phallus; and an anellus that is apically setose that are lacking in B. erae .

Description.—Head: Vertex and frontoclypeus with grayish-brown scales tipped with pale grayish brown. Outer surface of labial palpus grayish brown intermixed with pale grayish-brown scales along apical margin of second segment, inner surface paler. Antennal scape and pecten pale brown, flagellum brown; first flagellomere in male dilated, inner surface of dilated part with 47 palmate sex scales (n=1), ( Fig. 282 ). Proboscis pale grayish brown.

Thorax: Tegula and mesonotum agouti patterned, with brown on basal and apical 1/3s, and pale brown on middle 1/3. Legs brown intermixed with pale grayish-brown scales near midsegments and apical margins of segments and tarsomeres. Forewing ( Fig. 325 ): Length 5.9–7.5 mm (n = 27), pale grayish brown intermixed with grayish-brown scales and grayish-brown scales tipped with pale grayish brown, darker along basal 2/3 of costa and anal margin; submedian fascia absent; cell with three spots, one near middle, two on apical end along crossvein; marginal spots present. Undersurface brown. Venation ( Fig. 10 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent with CuA1 straight and CuA2 acutely curved basally. Hindwing: Translucent brown gradually darkening to apex. Venation ( Fig. 10 ) with cell closed, cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 77–78 ): Uncus gradually narrowed from a slightly widened base to subapical area, abruptly narrowed, forming narrowly rounded apex, slightly downcurved, sparsely setose, nearly equal to width of anal opening. Dorsal strut of tegumen absent. Gnathos narrow, confluent with tegumen, posteroventral margin slightly protracted mesially, bidentate. Sockets of tergal setae extending slightly beyond midlength of tegumen. Valva divided; ventral part parallelsided, narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose, greatly upturned from base, forming large fold, narrowing abruptly to near base of spinelike process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; digitate process slightly curved inwardly; area beneath costa overlaid with densely packed microtrichiate membrane extending above and below phallus to opposite side; basal ridge of digitate process protracted ventrally fusing with dorsolateral ridge of proximal flange; ventral margin of proximal flange slightly rounded basally, gradually narrowing to apicolateral margin, forming slightly narrowed and elongate ridge; membrane above proximal flange densely microtrichiate. Juxta bandlike. Vinculum semicircular. Phallus bulbous basally; phallus and sclerite of phallus longer than valva; sclerite of phallus sigmoidshaped; anellus parallelsided throughout most of length from base, broadly rounded apically, setose on apical 1/3. Female Genitalia ( Fig. 255 ): Apophyses posteriores slightly more than 3X longer than apophyses anteriores. Ostium bursae within densely packed microtrichiate membrane, slightly posterior to seventh segment. Posterior margin of seventh sternum slightly emarginate laterally, forming broad, slightly protuberant, truncate, median lobe. Ductus bursae slightly longer than apophyses posteriores; with two rows of imbricate platelets within anterior 1/2, gradually becoming less dense posteriorly. Inception of ductus seminalis arising from ductus bursae posterior to anterior margin of seventh sternum. Corpus bursae ovoid, spinulate; signum spinate, arising from small, rounded base near middle.

MAP 8. Distribution of Blastobasis deae (●).

Distribution (Map 8). Blastobasis deae is known from five collecting sites in western Costa Rica along the Cordillera de Guanacaste, two sites north of the Cordillera Central, and one site in the northeast along the Caribbean coast.

Etymology. The specific epithet deae is derived from the Latin dea, meaning goddess.
