( Figs. 4 , 65–66 , 276 , 319 , Map 4)

Diagnosis.— Blastobasis paludis is similar to B. lygdi in facies but differs from the latter by having a wider gnathos; a more inwardly curved apical process of the ventral part of the valva; and a longer phallus. B. paludis also has a dorsal strut of the tegumen that is lacking in B. lygdi .

Description.—Head: Vertex and frontoclypeus pale brown or brownish gray. Outer surface of labial palpus pale brown intermixed with few brown scales or brownish gray intermixed with pale brownish-gray scales along apical margin of second segment; inner surface pale brown or brownish gray. Antennal scape pale brown or brownish gray, pecten pale brown, flagellum gray; first flagellomere in male dilated, inner surface of dilated part with 39 palmate sex scales (n=1), ( Fig. 276 ). Proboscis brownish gray.

Thorax: Tegula brown on basal 1/2, pale brown or brownish gray on apical 1/2; mesonotum pale brown or brownish gray. Legs brownish gray intermixed with pale brownish-gray scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 319 ): Length 5.0–6.9 mm (n = 23), pale brown intermixed with few brown and brownish-yellow scales or pale brownish gray on basal 2/5, brownish gray on apical 3/5; submedian fascia present or absent, if present fascia complete or incomplete, faint or dark; cell with three spots, one near midcell, two on apical end along crossvein; marginal spots faint or dark. Undersurface brown. Venation ( Fig. 4 ) with M3 and CuA1 originating from common point along distoposterior part of cell, CuA1 straight, CuA2 slightly curved basally. Hindwing ( Fig. 4 ): Translucent pale brown or translucent pale brown darkening to apex. Venation ( Fig. 4 ) with cell closed, cubitus 4-branched with all veins arising submarginally from cubitus.

Abdomen: Male genitalia ( Figs. 65–66 ): Uncus gradually narrowed from widened base, rounded apically, slightly downcurved, sparsely setose, shorter than width of anal opening. Dorsal strut of tegumen linear, fused with base of uncus. 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 to midlength of tegumen. Valva divided; ventral part broadened basally, gradually narrowed apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin setose beyond base, upturned slightly near 1/3, 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; process slightly 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; flange bearing conical setae intermixed with densely packed microtrichiae, ventral margin slightly cleft basally, extending laterally, forming broadly-rounded ridge. Juxta bandlike. Vinculum semicircular. Phallus longer than valva, bulbous basally; sclerite of phallus shorter than valva, forming apical ring from a linear stem; anellus wider apically than basally, setose along margins. Female Genitalia: Unknown.

Distribution (Map 4). Blastobasis paludis is known from two collecting sites along the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet paludis is derived from the Latin palus, meaning swamp or marsh.
