Blastobasis orithyia Adamski , new species

( Figs. 15 , 91–92 , 289 , 332 , Map 12)

Diagnosis.— Blastobasis orithyia is similar to B. achaea in facies but differs from the latter by having the tergal setae extending to near the midlength of the tegumen; a more densely spinose apicoventral margin of the proximal flange of the dorsal part of the valva; and a more broadly rounded apical margin of the phallus.

Description.—Head: Scales on vertex and frontoclypeus brown tipped with pale brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margins of segments 1–2, inner surface paler [many scales missing]. Antennal scape and pecten pale brown, flagellum brown basally gradually brightening apically; first flagellomere in male dilated, inner surface of dilated part with 42 palmate sex scales (n=1), ( Fig. 289 ). Proboscis pale brown.

Thorax: Scales on tegula brown tipped with pale brown; mesonotum pale brown [many scales missing]. Legs with dark-brown scales tipped with pale brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 332 ): Length 5.0–5.3 mm (n = 8), pale brown intermixed with brown scales tipped with pale brown and dark-brown scales; cell with three brown spots, one spot near middle, two spots on apical end along crossvein. Undersurface brown. Venation ( Fig. 15 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 straight and CuA2 broadly curved. Hindwing: Translucent pale brown. Venation ( Fig. 15 ) with anterior part of cell closed, posterior part open; cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 91–92 ): Uncus slightly narrowed from base, broadly rounded apically, slightly downcurved, sparsely setose, shorter than width of anal opening. Dorsal strut of tegumen absent. Gnathos wide, confluent with tegumen, posteroventral margin slightly protracted mesially, bidentate; midwidth of pigmented part of gnathos slightly narrower than midwidth of uncus. Sockets of tergal setae extending to near midlength of tegumen. Valva divided; ventral part near parallelsided from base, abruptly narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose from about 1/5, upturned slightly from middle, forming narrow fold to near slightly raised, setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; digitate process broadly curved inwardly; area beneath costa overlaid with sparse 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 linear, extending laterally to a broadly rounded ridge; proximal flange bearing many conical setae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus slightly longer than valva; sclerite of phallus curved near 2/3; anellus wide basally, broadly rounded apically, setose. Female Genitalia: Unknown.

Distribution (Map 12). Blastobasis orithyia is known from three collecting sites in northwestern Costa Rica; one along the Cordillera de Guanacaste, and two in the dry-forest region.

Etymology. The specific epithet orithyia is chosen in honor of Orithyia , daughter of Erechtheus, a king of Athens.
