( Figs. 12 , 81–82 , 256 , 284 , 327 , Map 9)

Diagnosis.— Blastobasis iuanae is similar to B. xiphiae in facies but differs from the latter by having a less protuberant median lobe of the posteroventral margin of the gnathos; a wider ventral part of the valva; and a wider proximal flange of the dorsal part of the valva. B. iuanae also has and a bulbous base of the phallus that is lacking in B. xiphiae .

Description.—Head: Vertex and frontoclypeus with scales grayish brown tipped with pale grayish brown. Outer surface of labial palpus grayish brown intermixed with few brown scales, inner surface pale grayish brown. Antennal scape with scales grayish brown tipped with pale grayish brown, pecten brown, flagellum grayish brown; first flagellomere in male dilated, inner surface of dilated part with 21 palmate sex scales (n=1), ( Fig. 284 ). Proboscis grayish brown.

Thorax: Tegula agouti patterned, with basal and apical 1/3s grayish brown, and middle 1/3 with grayish-brown scales tipped with pale grayish brown; mesonotum with basal 1/4 grayish brown, apical 3/4 pale grayish brown. Legs grayish brown intermixed with pale grayish-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 327 ): Length 5.2–7.2 mm (n = 13), pale grayish-brown scales intermixed with grayish-brown scales tipped with pale grayish brown and grayish brown scales; base dark, gradually brightening to submedian fascia; submedian fascia complete or incomplete; cell with three spots, one near middle, two on apical end along crossvein; marginal spots slightly elongate forming short streaks. Undersurface brown. Venation ( Fig. 12 ) with M2 and M3 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 slightly curved near base and CuA2 acutely curved basally. Hindwing: Translucent pale brown. Venation ( Fig. 12 ) with anterior part of cell closed, posterior part open; cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 81–82 ): Uncus parallelsided for most of length, 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 about equal to midwidth of uncus. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part wide, narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose from 2/3, slightly upturned basally, forming narrow fold to near 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; basal ridge of digitate process protracted ventrally fusing with dorsolateral ridge of proximal flange; ventral margin of proximal flange extending ventrolaterally, forming subellipsoid and protuberant ridge; membrane above proximal flange bearing conical setae intermixed with densely packed microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus longer than valva, bulbous basally; sclerite of phallus about equal in length to phallus, sigmoid-shaped; anellus broadly rounded, setose along margin. Female Genitalia ( Fig. 256 ): Apophyses posteriores nearly 3X longer than apophyses anteriores. Eighth tergum with slightly elongate, darkly pigmented, median longitudinal streak on posterior end. Ostium bursae within densely packed microtrichiate membrane, slightly posterior to seventh segment; short, parallelsided duct, connecting widely dilated part of ductus bursae and inception of ductus seminalis from shared point; inception of ductus seminalis posterior to posterior margin of seventh sternum; posterior margin of seventh sternum greatly emarginate laterally, forming protuberant and truncate, median lobe. Ductus bursae slightly longer than apophyses posteriores; with two rows of imbricate platelets within anterior 1/3, gradually becoming sparser posteriorly. Corpus bursae ovoid, spinulate throughout, with small bulla on posterior end; signum spinate, arising from small, rounded base near middle.

Distribution (Map 9). Blastobasis iuanae is known from two collecting sites; one along the Cordillera de Tilarán in west-central Costa Rica, and one along the Cordillera de Talamanca near the border of Panama. Etymology. The specific epithet iuanae is derived from the Latin iuana, meaning door.
