Hypatopa rego Adamski , new species

( Figs. 38 , 189–190 , 381 , Map 38)

Diagnosis.— Hypatopa rego is similar to H. styga in facies but differs from the latter by having a slightly wider uncus; a more shallowly emarginate ventroposterior margin of the gnathos; a shorter phallus and sclerite of phallus; and a larger anellus. H. rego also has a slightly curved apical process of ventral part of valva; and a basally geniculate digitate process of dorsal part of valva that are lacking in H. styga .

Description.—Head: Vertex and frontoclypeus pale brown. Outer and inner surfaces of labial palpus with segments 1–2 brown intermixed with pale-brown scales along apical margins, segment 3 pale brown intermixed with few brown scales. Antennal scape pale brown intermixed with few brown scales, pecten brown, flagellum brownish gray. Proboscis pale brown.

Thorax: Tegula brown; mesonotum pale brown. Legs brown intermixed with pale-brown scales near midsegments and on apical margins of all segments and tarsomeres. Forewing ( Fig. 381 ): Length 4.2–5.3 mm (n = 6), pale brown scales intermixed with brown scales; basal 1/3 pale brown except costa brown; apical 2/3 brown intermixed with few pale-brown scales. Undersurface brown. Venation ( Fig. 38 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 straight and CuA2 acutely curved basally. Hindwing: Translucent pale brown gradually darkening to apex. Venation ( Fig. 38 ) with cubitus 4-branched; M2 branched near 1/3 and M3 and CuA1 branched near 2/3.

Abdomen: Male genitalia ( Figs. 189–190 ): Uncus near parallelsided from widened base to subapical area, gradually narrowing apically to rounded apex, straight, sparsely setose, about equal in length to width of anal opening. Gnathos, thin anteriorly directed band confluent with tegumen, ventroposterior margin protuberant, forming slightly raised, mesially emarginate lobe. Sockets of tergal setae extending to midlength of tegumen. Valva divided; ventral part slightly projecting inwardly, gradually widened to near middle, narrowing apically, forming large, nearly straight apical process; process setose on outer surface, planate on inner surface; ventral margin entire, widening to near middle, gradually narrowing to near an abruptly widened setose ridge at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process geniculate basally, slightly recurved apically; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange round, sparsely microtrichiate on dorsal 1/2, densely setose on surrounding, ventral 1/2; ventrolateral margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus about equal to length of valva; phallus straight, slightly bulbous basally, sclerite of phallus acutely curved near base and near middle; anellus parallelsided from wide base, narrowly rounded apically, bearing two elongate setal clusters on lateral surfaces. Female Genitalia: Unknown.

Distribution (Map 38). Hypatopa rego is known from two closely adjacent collecting sites along the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet rego is derived from the Latin regula meaning, a straight length or ruler.
