Blastobasis phaedra Adamski , new species

( Figs. 23 , 123–124 , 305 , 348 , Map 21)

Diagnosis.— Blastobasis phaedra is similar to B. nivis in facies but differs from the latter by having a larger uncus; the sockets of tergal setae not extending beyond the midlength of the tegumen; a wider basal ridge of the digitate process of the dorsal part of the valva; a smaller phallus; and an anellus that is wider.

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brown. Outer surface of labial palpus with segment 1 brown, segment 2 brown intermixed with pale-brown scales along apical margin, segment 3 brown intermixed with pale brown scales; inner surface pale brown. Antennal scape pale brown intermixed with few brown scales, pecten pale brown, flagellum brownish gray; first flagellomere in male dilated, inner surface of dilated part with 32 palmate sex scales (n=1), ( Fig. 305 ). Proboscis pale brown.

Thorax: Tegula pale brown on basal 2/3, brownish gray on apical 1/3; mesonotum brownish gray on basal 1/ 5, pale brownish gray on apical 4/5. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 348 ): Length 6.0–7.0 mm (n = 11), pale brown intermixed with brown scales; base dark gradually brightening to submedian fascia or abruptly brighted slightly beyond base to submedian fascia; submedian fascia complete or incomplete; cell with three spots, one near middle, two on apical end along crossvein; marginal spots present. Undersurface brown. Venation ( Fig. 23 ) with M3 closer to CuA1 near basal 1/2 than distance between M3 and CuA1 near basal 1/3; cubital veins divergent from bases; CuA1 straight, CuA2 broadly curved. Hindwing: Translucent pale brown or translucent pale brown gradually darkening to apex. Venation ( Fig. 23 ) with cell closed; cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 123–124 ): Uncus gradually narrowing from base, narrowly rounded apically, slightly downcurved, sparsely setose, about equal in length to width of anal opening. Dorsal strut of tegumen absent. Gnathos wide, confluent with tegumen, posteroventral margin slightly protracted mesially, narrowly bidentate. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part broadly curved dorsolaterally from beyond base, narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose from 1/5, slightly upturned, forming narrow fold to near slightly raised setose lobe at base of apical process; dorsal part with apical portion of costa slightly recurved, extending dorsolaterally, forming setose digitate process; area beneath costa and above proximal flange overlaid with dense microtrichiate membrane, extending above and below phallus to opposite side; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; ventral margin of proximal flange slightly cleft, extending laterally to angular, ventrolateral ridge; proximal flange bearing conical setae intermixed with sparse microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus slightly bulbous basally, sclerite of phallus subsigmoid-shaped; anellus slightly narrowed from base, broadly rounded apically, setose. Female Genitalia: Unknown.

MAP 21. Distribution of Blastobasis phaedra (●).

Distribution (Map 21). Blastobasis phaedra is known from six collecting sites; two in western Costa Rica along the Cordillera de Guanacaste, one north of the Cordillera Central, and three along the Pacific coastline near the mouth of the Golfo de Nicoya east to the Osa Peninsula.

Etymology. The specific epithet phaedra is chosen in honor of Phaedra , daughter of Minos.
