( Figs. 111–112 , 299 , 342 , Map 17)

Diagnosis.— Blastobasis custodis is similar to B. rotullae in facies but differs from the latter by having the sockets of tergal setae extending beyond the midlength of the tegumen; a more angular apicoventral margin of the proximal flange of the dorsal part of the valva; and a larger anellus.

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 and pecten pale brown, flagellum brown gradually darkening apically; first flagellomere in male dilated, inner surface of dilated part with 57 palmate sex scales (n=1), ( Fig. 299 ). Proboscis pale brown.

Thorax: Tegula and mesonotum pale brown [many scales missing]. Legs brown intermixed with pale-brown scales near midsegments and apical margins of all segments and tarsomeres [some legs missing]. Forewing ( Fig. 342 ): Length 8.2 mm (n = 1), pale brown intermixed with brown scales; cell with three brown spots, one spot near middle, two spots on apical end along crossvein; marginal spots brown. Undersurface brown. Hindwing: Translucent brown gradually darkening to apex.

Abdomen: Male genitalia ( Figs. 111–112 ): Uncus slightly narrowed from base, narrowly rounded apically, slightly downcurved, sparsely setose, slightly shorter than width of anal opening. Dorsal strut of tegumen absent. Gnathos narrow, confluent with tegumen, posteroventral margin slightly protracted mesially, narrowly bidentate. 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 beyond base, upturned slightly near 1/5, 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; area beneath costa overlaid with densely packed microtrichiate membrane extending above and below phallus to opposite side; ventral ridge of digitate process protracted ventrally fusing with proximal flange; ventral margin of proximal flange linear, extending laterally, forming angularly rounded, apicoventral ridge; proximal flange densely microtrchiate. Juxta bandlike. Vinculum semicircular. Phallus slightly bulbous basally; phallus and sclerite of phallus longer than valva; sclerite of phallus acutely recurved apically; anellus slightly widened apically from base, shallowly notched apically, setose. Female Genitalia: Unknown.

Distribution (Map 17). Blastobasis custodis is know from one collecting site on the western most part of the Cordillera de Guanacaste in the northwestern part of Costa Rica.

Etymology. The specific epithet custodis is derived from the Latin custos meaning, protector.
