Hypatopa cyane Adamski, new species

(Figs. 33, 167–168, 370, Map 32)

Diagnosis.— Hypatopa cyane is similar to H. plebis and H. dolo in facies but differs from the latter two by having a laterally flattened apical part of the uncus; a subquadrate apical margin of proximal flange of the dorsal part of the valva; a slightly bulbous base of the phallus; and a setose anellus on the basal 1/2. These features are lacking in H. plebis and H. dolo .

Description.—Head: Scales on vertex and frontoclypeus grayish brown tipped with pale grayish brown. Outer surface of labial palpus segment 1 brown, segment 2 brown intermixed with pale-brown scales along apical margin, segment 3 brown intermixed with pale-brown scales; inner surface brown intermixed with pale-brown scales or pale brown. Antennal scape pale brown, pecten brown, flagellum grayish brown. Proboscis pale brown.

Thorax: Tegula with basal 1/3 grayish brown, apical 2/3 pale grayish brown; mesonotum with basal 1/5 brown, apical 4/5 pale grayish brown. Legs brown intermixed with pale brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing (Fig. 370): Length 4.1–5.1 mm (n = 12), basal 1/3 pale brown intermixed with few brown scales, apical 2/3 brown intermixed with pale-brown scales; cell with three spots, one near middle, two on apical end along crossvein; marginal spots faint or absent. Undersurface brown. Venation (Fig. 33) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 straight and CuA2 broadly rounded. Hindwing: Translucent pale brown, gradually darkening to apex. Venation (Fig. 33) with cubitus 4-branched with M2 arising about 1/2 distance between distoposterior part of cell and branching point of M3 and CuA1.

Abdomen: Male genitalia (Figs. 167–168): Uncus narrowed from single-tiered base, acutely downcurved and laterally flattened apically, sparsely setose, nearly equal in length to width of anal opening. Gnathos, narrow band, confluent with tegumen, ventroposterior margin narrowly emarginate mesially. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, gradually widened to middle, gradually narrowed to base of inwardly curved, spinelike apical process; process acutely curved at 1/3, setose on outer surface, planate on inner surface; ventral margin slightly upturned beyond middle, forming narrow fold to near marginal ridge at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process broadly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange subrectangular, bearing sparse microtrichiae on dorsal 1/2, hairlike setae on ventral 1/2; margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus about equal to length of valva, slightly curved from middle; anellus about 1/3 length of phallus, parallelsided, broadly rounded apically, setose on basal 1/2. Female Genitalia: Unknown.

Distribution (Map 32). Hypatopa cyane is known from five collecting sites in northwestern Costa Rica along or near the Cordillera de Guanacaste.

Etymology. The specific epithet cyane is chosen in honor of Cyane, a nymph changed into a fountain for her grief of the loss of Proserpine.
