Review of the Blastobasinae of Costa Rica (Lepidoptera: Gelechioidea: Blastobasidae) Author Adamski, David text Zootaxa 2013 3618 1 1 223 journal article 39040 10.11646/zootaxa.3618.1.1 d2a7d193-4512-4565-a56e-49034dcf6101 1175-5326 247396 B548B139-E8D9-4F10-956E-E0001E6C7586 Blastobasis aedes Adamski , new species ( Figs. 24 , 125–126 , 306 , 349 , Map 22) Diagnosis.— Blastobasis aedes is similar to B. tapetae in facies but differs from the latter by having a threetiered uncus; a less protuberant mesial part of the gnathos; an apicoventral margin of the ventral part of the valva that is less greatly upturned; and a more densely spinose apicoventral margin of the proximal flange of the dorsal part of the valva. B. aedes also has a dorsal strut and a sigmoid-shaped sclerite of the phallus that are lacking in B. tapetae . Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brown. Outer surface of labial palpus with segment 1 brown, segment 2 brown intermixed with pale-brown scales along apical margin, segment 3 pale brown intermixed with few brown scales; inner surface pale brown. Antennal scape pale brown intermixed with few brown scales, pecten pale brown, flagellum brownish gray; first flagellomere in male dilated, inner surface of dilated part with 31 palmate sex scales (n=1), ( Fig. 306 ). Proboscis pale brown. Thorax: Tegula with basal 1/3 brown, apical 2/3 pale brown; mesonotum with basal 1/2 brown, apical 1/2 pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 349 ): Length 4.9–6.8 mm (n = 20), pale brown intermixed with few brown scales; cell with three spots, one near middle, two on apical end along crossvein; submedian fascia present or absent, if present, basal area gradually brightening to inner margin of fascia; marginal spots present or absent. Undersurface brown. Venation ( Fig. 24 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases, CuA1 straight, CuA2 curved basally. Hindwing: Translucent pale brown or translucent pale brown gradually darkening to apex. Venation ( Fig. 24 ) with cell closed; cubitus 4-branched with all veins arising submarginally from cubitus. Abdomen: Male genitalia ( Figs. 125–126 ): Uncus three-tiered, each gradually narrowed from base, apex narrowly rounded, slightly downcurved, sparsely setose, about equal in length to width of anal opening. Dorsal strut of tegumen linear, fusing to base of uncus. Gnathos wide, confluent with tegumen, posteroventral margin slightly protracted mesially, widely bidentate; midwidth of pigmented part of gnathos narrower than midwidth of uncus. Sockets of tergal setae extending slightly 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, 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; digitate process abruptly curved near midlength; area beneath costa above proximal flange overlaid with dense microtrichiate membrane, extending above and below phallus to opposite side; basal ridge of digitate process densely setose, protracted ventrally fusing with dorsolateral ridge of proximal flange; ventral margin of proximal flange broadly cleft, extending ventrolaterally forming broadly rounded, serrate, ventrolateral ridge; proximal flange bearing conical setae intermixed with sparse microtrichiae. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; sclerite of phallus sigmoid-shaped; anellus parallelsided from base, narrowing from subapical region to apex, setose mostly along margins.

Blastobasis aedes is known from three collecting sites in northwestern Costa Rica near the western most part of the Cordillera de Guanacaste. Etymology. The specific epithet aedes is derived from Latin meaning, a building. MAP 22. Distribution of Blastobasis aedes (●) and B. tapetae (˔).
