Blastobasis manto Adamski, new species (Figs. 131–132, 309, 352, Map 23) Diagnosis.— Blastobasis manto is similar to B. rotae in facies but differs from the latter by having a longer uncus; a shorter pigmented part of the gnathos; a narrower and broadly curved apical process of the ventral part of the valva; a narrower basal ridge of the digitate process of the dorsal part of the valva; a more spinose proximal flange; and a more acutely curved phallus from 3/4. Description.—Head: Vertex and frontoclypeus pale brown. Outer surface of labial palpus pale brown intermixed with few brown scales, inner surface pale brown. Antennal scape pale brown, [pecten missing], flagellum brown; first flagellomere in male dilated, inner surface of dilated part with 53 palmate sex scales (n=1), (Fig. 309). Proboscis pale brown. Thorax: Tegula and mesonotum pale brown. Legs pale brown intermixed with few brown scales [many scales missing]. Forewing (Fig. 352): Length 5.9 mm (n = 1), pale brown intermixed with brown scales; submedian fascia complete, faint; cell with a brown spot near middle. Undersurface brown. Hindwing: Translucent pale brown. Abdomen: Male genitalia (Figs. 131–132): Uncus slightly narrowed from base, broadly rounded apically, slightly downcurved, sparsely setose, shorter in length to width of anal opening. Dorsal strut of tegumen absent. Gnathos narrow, confluent with tegumen, posteroventral margin greatly protracted mesially, bidentate; midwidth of pigmented area of gnathos about equal in width to midwidth of uncus. 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 1/6, slightly upturned from 1/6 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 slightly curved inwardly; area beneath costa overlaid by membrane with sparse microtrichiate, 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 linear, extending laterally, forming a broadly rounded, serrate ridge; proximal flange bearing several spines intermixed with hairlike setae and sparse microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus slightly longer than valva, both abruptly curved at 3/4; anellus gradually narrowed from base, broadly rounded apically, setose. Female Genitalia: Unknown. Holotype, 3, “ COSTA RICA, San Jos, Cuidad Colon, El Rodeo, 950 m, 21-VI-1998, C19-22L, F, Col. Kenji Nishida, “INBio 3 Genitalia Slide by D. Adamski, No. 4036 [yellow label]. Distribution (Map 23). Blastobasis manto is known from one collecting site in south-central Costa Rica. Etymology. The specific epithet manto is chosen in honor of Manto, daughter of the Theban seer Tiresias.
