Blastobasis deliciolarum Adamski , new species

( Figs. 20, 113–114, 300, 343, Map 18)

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

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Outer surface of labial palpus brownish gray intermixed with pale brownish-gray scales along apical margins of segments 1–2, inner surface pale brown. Antennal scape and pecten brownish gray, flagellum brown; first flagellomere in male dilated, inner surface of dilated part with 55 palmate sex scales (n= 1), ( Fig. 300). Proboscis pale brown.

Thorax: Tegula and mesonotum brownish gray intermixed with brownish-gray scales tipped with pale brownish gray. Legs brownish gray intermixed with pale brownish-gray scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 343): Length 4.0–6.7 mm (n = 20), with brownish-gray scales tipped with pale brownish gray intermixed with brown and pale brownish-gray scales; base dark gradually brightening to submedian fascia; cell with three spots, one near middle, two on apical end along crossvein; marginal spots present. Undersurface brown. Venation ( Fig. 20) with M 3 slightly curved; cubital veins divergent from bases; CuA 1 nearly straight, CuA 2 broadly curved. Hindwing: Pale brown gradually darkening to apex. Venation ( Fig. 20) with anterior part of cell closed, posterior part of cell open; cubitus 4 -branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 113–114): 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 wide, confluent with tegumen, posteroventral margin slightly protracted mesially, narrowly 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 slightly beyond 1 / 3, upturned near middle, forming a wide fold to near slightly raised setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming sigmoidshaped, setose, digitate process; digitate process geniculate basally; area beneath costa overlaid with sparse microtrichiae 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 to rounded, apicoventral ridge; proximal flange bearing numerous conical setae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus curved at 2 / 3, longer than valva; anellus widened basally, parallelsided, broadly rounded apically, setose along lateral margins. Female Genitalia: Unknown.

MAP 18. Distribution of Blastobasis deliciolarum (●) and B. abollae (˔).

Distribution (Map 18). Blastobasis deliciolarum is known from five collecting sites; three along the western most part of the Cordillera de Guanacaste, one to the south in the dry-forest region, and one along the Cordillera de Talamanca near the border of Panama.

Etymology. The specific epithet deliciolarum is derived from the Latin deliciolae meaning, darling.
