description: Blastobasis echus Adamski, new species
(Figs. 17, 99–100, 293, 336, Map 14)
Diagnosis.— Blastobasis echus is similar to B. usurae in facies but differs from the latter by having a wider anal opening; a more elongate pigmented part of the gnathos; sockets of tergal setae extending beyond the midlength of the tegumen; a wider proximal flange of the dorsal part of the valva; a larger phallus; and an apex of the anellus that is more emarginate mesially. B. echus also has and an anellus that is setose only along its lateral margins, a feature that is lacking in B. usurae.
Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Outer and inner surfaces of labial palpus with brownish-gray scales tipped with pale brownish gray, and pale brownishgray scales along apical margins of segments 1–2. Antennal scape with brownish-gray scales tipped with pale brownish gray, pecten brown, flagellum dark brownish gray; first flagellomere in male dilated, inner surface of dilated part with 56 palmate sex scales (n=1), (Fig. 293). Proboscis pale brownish gray.
Thorax: Tegula with brownish-gray scales tipped with pale brownish gray; mesonotum with basal 1/4 brownish gray, apical 3/4 with scales brownish gray tipped with pale brownish gray. Forewing (Fig. 336): Length 4.1–8.5 mm (n = 140), brownish-gray scales tipped with pale brownish gray intermixed with brownish-gray scales and pale brownish-gray scales; basal 1/3 pale brownish gray intermixed with few brownish-gray scales except, costa brownish gray or base dark gradually brightening to 1/3; submedian fascia complete or incomplete; apical 2/ 3 dark basally, gradually brightening to apex; cell with three spots, one near middle, two on apical end along crossvein; marginal spots appear as short streaks on apical portions of radial and medial veins. Undersurface brown. Venation (Fig. 17) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases, CuA1 slightly curved, CuA2 broadly curved. Hindwing: Translucent pale brown. Venation (Fig. 17) with anterior part of cell closed, posterior part of cell open; cubitus 4-branched with all veins arising submarginally from cubitus.
MAP 14. Distribution of Blastobasis echus (●).
Abdomen: Male genitalia (Figs. 99–100): Uncus slightly narrowed from base, broadly rounded apically, slightly downcurved, sparsely setose; shorter than width of anal opening. Dorsal strut of tegumen absent. Gnathos wide, confluent with tegumen, posteroventral margin slightly protracted mesially, bidentate; midwidth of pigmented part of gnathos 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 about 1/5, upturned greatly beyond base, forming wide fold to near base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; digitate process broadly curved inwardly; area beneath costa overlaid with densely packed microtrichiate 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 slightly cleft, extending laterally to a broadly rounded, apicoventral ridge; proximal flange bearing densely packed microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus longer than valva, bulbous basally; sclerite of phallus shorter than valva, acutely curved near 2/3; anellus near parallelsided from base, apically notched mesially, setose along margin. Female Genitalia: Unknown.

Distribution (Map 14). Blastobasis echus is known from several collecting sites near or along the Cordillera de Guanacaste, the Cordillera de Tilarán, and the Cordillera de Talamanca; two dry-forest sites in northwestern Costa Rica, one site in the north-central part of the country near the border of Nicaragua, and two sites along eastern Pacific Coast.
Etymology. The specific epithet echus is derived from the Latin echo.
