Hypatopa io Adamski, new species

( Figs. 40 , 209–210 , 391 , Map 43)

Diagnosis.— Hypatopa io is similar to H. leda in facies but differs from the latter by having a larger uncus; a more protuberant median lobe of the ventroposterior margin of the gnathos; a more upturned ventral margin of the ventral part of the valva; a more densely microtrichiate basal part of the proximal flange of the dorsal part of the valva; and a longer phallus and anellus. H. io also has a recurved digitate process of the dorsal part of the valva; an acutely curved apical process of the ventral part of the valva; a serrate margin of proximal flange; and an anellus that is shallowly emarginate mesially, with two irregular rows of subapical setal clusters and two marginal setae near base that are lacking in H. leda .

Description.—Head: Vertex and frontoclypeus pale yellowish brown. Outer surface of labial palpus pale yellowish brown intermixed with few brown scales, inner surface pale yellowish brown. Antennal scape and pecten pale yellowish brown, flagellum brownish gray. Proboscis pale yellowish brown.

Thorax: Tegula with basal 1/3 brown, apical 2/3 pale yellowish brown; mesonotum yellowish brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 391 ): Length 5.5–6.2 mm (n = 7), pale yellowish brown intermixed with brown scales near millde, including area from crossvein to apex; cell with three spots, one near middle, two on apical end along crossvein. Undersurface brown anterior to CuP, pale brown posterior to CuP. Venation ( Fig. 40 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; M2 closer to M1 than to M3; cubital veins divergent from bases with CuA1 slightly curved and CuA2 broadly curved basally. Hindwing: Translucent pale brown. Venation ( Fig. 40 ) with cubitus 4-branched; M2 arising less than 1/3 and M3 and CuA2 branched near 1/2.

Abdomen: Male genitalia ( Figs. 209–210 ): Uncus narrowed from widened base, constricted near middle, forming rounded apical part, slightly downcurved, sparsely setose, shorter than width of anal opening. Gnathos, narrow band, confluent with tegumen; ventroposterior margin slightly protuberant, forming shallowly emarginate median lobe. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part broadly rounded basally, nearly parallelsided to base of large, inwardly curved, apical process; process acutely curved from base, setose outer surface, planate on inner surface; ventral margin setose, greatly upturned near middle, forming wide fold to near small, setose marginal ridge on base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process geniculate basally, recurrent apically; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange subquadrate, with broadly rounded apical margin, microtrichiate on basal 2/3, spiculate and sparsely setose on apical 1/3; margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, slightly bulbous basally, apically truncate, notched mesially; sclerite of phallus slightly curved near middle, mesially emarginate apically; anellus about 1/2 length of phallus, with two irregular rows of subapical setal clusters along lateral margins, and two marginal setae near base. Female Genitalia: Unknown.

Distribution (Map 43). Hypatopa io is known from two collecting sites; one on the Cordillera de Guanacaste, and one site on the Cordillera de Tilarán in western Costa Rica.

Etymology. The specific epithet io is named in honor of the daughter of Inachus, a stream god.
