Diagnosis.— Blastobasis beo is similar to B. dicionis in facies but differs from the latter by having a shorter uncus, a wider ventral part of the valva, a wider proximal flange of the dorsal part of the valva, and a lesser curved and a more sparsely setose anellus.

Description.—Head: Vertex and frontoclypeus pale brown [many scales missing]. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margins of segments 1–2, inner surface paler. Antennal scape with brown scales tipped with pale brown, [pecten missing], flagellum brown; first flagellomere in male dilated, inner surface of dilated part with 43 palmate sex scales (n=1), ( Fig. 311 View FIGURES 308 – 311 ). Proboscis pale brown.

Thorax: Tegula and mesonotum pale brown [many scales missing]. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 354 View FIGURES 352 – 359 ): Length 4.9–5.8 mm (n = 3), pale brown intermixed with brown scales; cell with a short, brown streak near middle. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia ( Figs. 135–136 View FIGURES 135 – 140 ): Uncus slightly narrowed from base, broadly rounded apically, slightly downcurved, sparsely setose, shorter than width of anal opening. Dorsal strut of tegumen narrow, fusing with base of uncus. Gnathos wide, confluent with tegumen, posteroventral margin greatly protracted mesially, bidentate; midwidth of pigmented area of gnathos about equal to midwidth of uncus. Sockets of tergal setae not 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 from 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 by membrane with densely packed microtrichiae, 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 cleft basally, extending ventrolaterally, forming broadly rounded ridge; proximal flange bearing several conical setae intermixed with sparse microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus slightly shorter than valva, both abruptly curved basally and beyond 1/2; anellus slightly narrowed from base, apically rounded, setose. Female Genitalia: Unknown.

Distribution (Map 24). Blastobasis beo is known from two collecting sites in northwestern Costa Rica on the western most part of the Cordillera de Guanacaste.

Etymology. The specific epithet beo is derived from the Latin meaning, “to bless or “enrich.
