( Figs. 9 , 75–76 , 254 , 281 , 324 , Map 7)

Diagnosis.— Blastobasis furtivus is similar to B. caetrae in facies but differs from the latter by having a shorter uncus; a less protuberant bidentate median process on posteroventral margin of the gnathos; a shorter proximal flange of the dorsal part of the valva; a longer phallus; and a longer ductus bursae in the female.

Description.—Head: Vertex brown; frontoclypeus pale brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margin of segment 2, inner surface paler. Antennal scape and pecten pale brown, flagellum grayish brown gradually brightening apically; first flagellomere in male dilated, inner surface of dilated part with 18 palmate sex scales (n=1), ( Fig. 281 ). Proboscis pale brown.

Thorax: Tegula brown or pale brown; mesonotum brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of segments and tarsomeres. Forewing ( Fig. 324 ): Length 4.0–6.2 mm (n = 44), pale brown intermixed with brown scales; basal area near costa and submedian fascia brown; submedian fascia complete or incomplete; cell with three spots, one near middle, two near apical end along crossvein; marginal spots present. Undersurface brown. Venation ( Fig. 9 ) with R5 straight or slightly curved; cubital veins separate with M3 nearly straight and cubital veins divergent from bases, with CuA1 nearly straight and CuA2 broadly curved. Hindwing: Translucent brown or translucent brown gradually darkening to apex. Venation ( Fig. 9 ) with cell closed with posterior part of crossvein weak; cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 75–76 ): Uncus gradually narrowed from 1/3, narrowly rounded apically, sparsely setose, longer than width of anal opening. Dorsal strut of tegumen absent. Gnathos wide, confluent with tegumen, posteroventral margin greatly protracted mesially, bidentate; midwidth of pigmented part of gnathos about equal to midwidth of uncus. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part broadened basally, gradually narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose, slightly upturned from 1/4, forming narrow fold to elongate, slightly raised, setose lobe at base of spinelike process; dorsal part with apical portion of costa extending dorsally, 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; base of ventral margin of proximal flange slightly cleft, extending laterally, forming ellipsoid and protuberant ridge; membrane above proximal flange bearing conical setae intermixed with sparse microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; sclerite of phallus sigmoid-shaped; anellus parallelsided throughout length from base, broadly rounded apically, setose along margin. Female Genitalia ( Fig. 254 ): Apophyses posteriores slightly more than 3X longer than apophyses anteriores. Eighth tergum with elongate, darkly pigmented, median longitudinal streak. Ostium bursae within sparsely microtrichiate membrane, slightly posterior to seventh segment; a short, parallelsided duct, connecting with widened part of ductus bursae and inception of ductus seminalis from shared point. Posterior margin of seventh sternum emarginate laterally, forming broad and protuberant, truncate, median lobe. Ductus bursae slightly more than 2X length of apophyses posteriores; with two rows of imbricate platelets within anterior 1/4, gradually becoming sparser posteriorly. Corpus bursae ovoid, spinulate; signum spinate, arising from small, rounded base near middle.

MAP 7. Distribution of Blastobasis furtivus (●).

Distribution (Map 7). Blastobasis furtivus is known from three collecting sites in western Costa Rica along the Cordillera de Guanacaste and the Cordillera de Tilarán; a site north of the Cordillera Central; a site along the eastern most part of the Cordillera de Talamanca near the border of Panama; two collecting sites along the Pacific Coast; and two coastal sites in the north. The distribution of this species appears to be throughout all of Costa Rica. Etymology. The specific epithet is derived from the Latin furtivus , meaning a secret.
