Hypatopa dux Adamski , new species

( Figs. 203–204 , 388 , Map 41)

Diagnosis.— Hypatopa dux is similar to H. nox in facies but differs from the latter by having a less protuberant median lobe of the ventroposterior margin of the gnathos; and a narrower apical process of the ventral part of the valva. H. dux also has an inwardly curved digitate process of the dorsal part of the valva; an apically quadrate and serrate margin of the proximal flange of the dorsal part of the valva; a longer phallus; a singly-coiled sclerite of the phallus; and a broadly truncate apical part of the anellus that are lacking in H. nox .

Description.—Head: Scales on vertex and frontoclypeus brown tipped with pale grayish brown. Outer surface of labial palpus brown, inner surface pale brown. Antennal scape brown intermixed with few pale-gray scales along apical margin, pecten pale brown, flagellum brown on basal 3/4, pale gray on apical 1/4; first flagellomere unmodfied in male. Proboscis pale grayish brown.

Thorax: Tegula and mesonotum grayish brown. Legs grayish brown intermixed with pale grayish-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 388 ): Length 5.0–5.6 mm (n = 3), brown intermixed with few pale-brown scales. Undersurface brown. Hindwing: Translucent pale brown gradually darkening to apex.

Abdomen: Male genitalia ( Figs. 203–204 ): Uncus gradually narrowed from widened base, acutely curved and rounded apically, sparsely setose, about equal in length to width of anal opening. Gnathos narrow, anteriorly directed band, confluent with tegumen; ventroposterior margin slightly protuberant mesially, forming shallowly emarginate lobe. Sockets of tergal setae not extending to midlength of tegumen. Valva divided; ventral part protracting basally, gradually widening to middle, narrowing to base of large, inwardly curved apical process; process slightly curved, setose on outer surface, planate on inner surface; ventral margin sparsely setose to near short, abruptly dilated, setose marginal ridge beneath apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process geniculate basally; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange subquadrate, slightly wider apically than at base, sparsely microtrichiate on basal 1/2, densely densely setose on apical 1/2; margin deeply serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, margin undulate; sclerite of phallus singly coiled; anellus parallelsided from widened base, truncate apically, with short row of setae on lateral margins of apical 1/2. Female Genitalia: Unknown.

Paratypes (2 3): same data as for holotype except, “Set., 1991, “CRI000, 491868, “Slide No. 2669, “USNM 84014; “ Oct. 1991, “CRI000, 354144, “Slide No. 2670, “USNM 84015. [2 in USNM].

Distribution (Map 41). Hypatopa dux is known from one collecting site on the Cordillera de Talamanca in southeastern Costa Rica near the border of Panama.

Etymology. The specific epithet dux is derived from the Latin meaning, a guide or conductor.
