Blastobasis abollae Adamski , new species

( Figs. 115–116 , 301 , 344 , Map 18)

Diagnosis.— Blastobasis abollae is similar to B. deliciolarum in facies but differs from the latter by having a longer uncus; a wider pigmented part of the gnathos; a less densely spinose apicoventral margin of the proximal flange of the dorsal part of the valva; and an anellus that is more narrowly rounded apically. B. abollae also has a dorsal strut of the tegumen that is lacking in B. deliciolarum .

Description.—Head: Vertex and frontoclypeus pale brown. Outer and inner surfaces of labial palpus pale brown. Antennal scape pale brown [pecten missing], flagellum brownish gray gradually brightening apically; first flagellomere in male dilated, inner surface of dilated part with 50 palmate sex scales (n=1), ( Fig. 301 ). Proboscis pale brown.

Thorax: Tegula and mesonotum pale brown intermixed with few brown scales [many scales missing]. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 344 ): Length 6.8 mm (n = 1), pale brown intermixed with few brown scales; cell with a short, brown streak near middle and two brown spots on apical end along crossvein; marginal spots brown. Undersurface brown. Hindwing: Pale brown.

Abdomen: Male genitalia ( Figs. 115–116 ): Uncus slightly narrowed from base, narrowly rounded apically, slightly downcurved, sparsely setose, about equal in length to width of anal opening. Dorsal strut of tegumen constricted near middle, fused with base of uncus. Gnathos wide, confluent with tegumen, posteroventral margin slightly protracted mesially, narrowly bidentate; midwidth of pigmented part of gnathos slightly narrower than midwidth of uncus. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part angled dorsolaterally from beyond base, narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose from 1/4, upturned, forming narrow fold to near slightly raised, setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming digitate and setose process; digitate process slightly curved inwardly, apically dilated; area beneath costa overlaid with densely packed microtrichiae 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 rounded, apicoventral ridge; proximal flange bearing numerous hairlike setae intermixed with small spinules and sparse microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; sclerite of phallus sigmoid-shaped; anellus gradually narrowing from base, slightly notched apically, setose mostly along lateral margins. Female Genitalia: Unknown.

Distribution (Map 18). Blastobasis abollae is known from one collecting site along the eastern part of the Cordillera de Talamanca near the border of Panama.

Etymology. The specific epithet abollae is derived from the Latin abolla meaning, a thick cloak.
