Blastobasis neniae Adamski , new species

( Figs. 14 , 87–88 , 287 , 330 , Map 11)

Diagnosis.— Blastobasis neniae is similar to B. graminea but differs from the latter by having a narrower uncus; a wider pigmented part of the gnathos; and a longer anellus. B. neniae also lacks a forewing with a streaked pattern of dark scales overlaid on the major veins; and has a dorsal strut of the tegumen that is lacking in B. graminea .

Description.—Head: Vertex and frontoclypeus brown. Outer surface of labial palpus brown, intermixed with pale-brown scales along apical margins of segments 1–2; inner surface paler. Antennal scape and pecten pale brown, flagellum brown gradually brightening apically; first flagellomere in male dilated, inner surface of dilated part with 37 palmate sex scales (n=1), ( Fig. 287 ). Proboscis pale brown.

Thorax: Tegula and mesonotum pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 330 ): Length 5.7 mm (n = 1), pale-brown intermixed with brown scales or pale-brown scales tipped with white intermixed with brown scales tipped with pale brown and few dark-brown scales; base brown; area beyond paler than apical 2/3; median fascia faint, complete or incomplete; cell with three dark-brown spots, one spot near middle, two spots on apical end along crossvein. Undersurface brown. Venation ( Fig. 14 ) with M3 and CuA1 nearly straight, arising from a common point on distoposterior part of cell; CuA1 and CuA2 nearly straight, divergent from bases. Hindwing: Translucent pale brown gradually darkening to apex. Venation ( Fig. 14 ) with anterior part of cell closed, posterior part open; cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 87–88 ): Uncus nearly parallelsided from widened base, slightly truncate apically, slightly downcurved, sparsely setose, shorter than width of anal opening. Dorsal strut of tegumen linear, fusing with base of uncus. Gnathos wide, confluent with tegumen, posteroventral margin slightly protracted mesially, bidentate; midwidth of pigmented part of gnathos equal to midwidth of uncus. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part nearly parallelsided, narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose, upturned beyond base, forming narrow fold to near slightly to setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; process broadly curved inwardly; area beneath costa 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 linear, extending laterally, forming narrowly ellipsoid and protuberant ridge; proximal flange bearing densely packed microtrichiae intermixed with few hairlike setae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus about equal in length to valva; sclerite of phallus sigmoid-shaped; anellus wide basally, broadly rounded apically, setose. Female Genitalia: Unknown.

MAP 11. Distribution of Blastobasis neniae (●) and B. achaea (˔).

Distribution (Map 11). Blastobasis neniae is known from eight collecting sites from the western part of Costa Rica; three along the Cordillera de Guanacaste, two along the Cordillera de Tilarán, and three along or near the Pacific Coastal dry-forest region.

Etymology. The specific epithet neniae is derived from the Latin nenia, meaning a mournful song.
