Hypatopa dicax Adamski , new species

( Figs. 217–218 , 395 , Map 45)

Diagnosis.— Hypatopa dicax is similar to H. ira in facies but differs from the latter by having an apically wider uncus; a basally constricted and narrower proximal flange of the dorsal part of the valva; and a longer phallus. H. dicax also has an entire ventroposterior margin of the gnathos; a downcurved apical process of the ventral part of the valva; a twisted digitate process of the dorsal part of the valva; and an acutely curved sclerite of the phallus that are lacking in H. ira .

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. 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. Antennal scape and pecten pale brown, flagellum brown basally gradually brightening apically. Proboscis pale brown.

Thorax: Tegula and mesonotum with brownish-gray scales tipped with pale brownish gray. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 395 ): Length 8.1 mm (n = 1), pale brown intermixed with few brown scales; submedian fascia faint. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia ( Figs. 217–218 ): Uncus parallelsided from broadly widened base, rounded apically, slightly downcurved, sparsely setose, about equal in length to width of anal opening. Gnathos, narrow band (not shown), confluent with tegumen; ventroposterior margin entire. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, widening to middle, gradually narrowing to large, ventrally curved, hinged, apical process; process acutely curved from base, setose on outer surface, planate on inner surface; ventral margin sparsely setose, with small, setose marginal ridge at base of apical process; apical part with costa extending dorsally, forming inwardly curved, setose digitate process; process twisted near midlength; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange apically ellipsoid, densely microtrichiate on basal 2/3, densely setose on apical 1/3; margin shallowly serrate. Juxta divided. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, sclerite of phallus acutely curved near 2/3 and slightly curved near base; anellus gradually narrowing from wide base, broadly rounded apically, setose along midregion. Female Genitalia: Unknown.

MAP 45. Distribution of Hypatopa dicax (●) and H. ira (˔).

Distribution (Map 45). Hypatopa dicax is known from one collecting site on the Cordillera de Talamanca in eastern Costa Rica.

Etymology. The specific epithet dicax is derived from the Latin meaning, ready of speech or witty.
