Hypatopa styga Adamski , new species

( Figs. 191–192 , 382 , Map 38)

Diagnosis.— Hypatopa styga is similar to H. rego in facies but differs from the latter by having a slightly narrower uncus; a longer phallus and sclerite of phallus; and a smaller anellus. H. styga also has a deeply emarginate ventroposterior margin of the gnathos; an acutely curved apical process of ventral part of valva; and a slightly curved base of the digitate process of dorsal part of valva that are lacking in H. rego .

Description.—Head: Vertex, frontoclypeus, and scape pale brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margins of segments 1–2, terminal segment pale brown; inner surface pale brown. Antenna pale brown. Proboscis pale grayish brown.

Thorax: Tegula with grayish-brown scales tipped with pale grayish brown on basal 1/2, pale grayish brown on apical 1/2; mesonotum with grayish-brown scales tipped with pale grayish brown. Legs brown intermixed with pale grayish-brown scales near midsegments and along apical margins of tarsomeres [hindlegs missing]. Forewing ( Fig. 382 ): Length 5.0 mm (n = 1), pale brown intermixed with brownish-orange and brown scales; cell with three faint spots, one near middle, two on apical end along crossvein. Undersurface brown. Hindwing: Translucent pale brown gradually darkening to apex.

Abdomen: Male genitalia ( Figs. 191–192 ): Uncus gradually narrowed from widened base, constricted near middle, forming slightly widened apical part; apical part acutely curved, sparsely setose, about equal in length to width of anal opening. Gnathos, thin anteriorly directed band, confluent with tegumen, ventroposterior margin emarginate mesially. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part slightly projecting inwardly, gradually widened before middle, narrowing apically, forming large, inwardly curved, apical process; process setose on outer surface, planate on inner surface; ventral margin slightly upturned beyond middle, forming narrow fold to near base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process slightly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsal ridge of proximal flange; flange subellipsoid, sparsely microtrichiate on dorsal 1/2, densely setose on ventral 1/2; margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus basally curved, sclerite of phallus broadly curved near middle, acutely curved basally; anellus gradually narrowed from wide base, broadly rounded apically, bearing two elongate setal clusters on lateral surfaces. Female Genitalia: Unknown.

Distribution (Map 38). Hypatopa styga is known from one collecting site on the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet styga is derived from the Latin Styx meaning, a river that separates the world of the living from the world of the dead.
