Hypatopa nex Adamski , new species

( Figs. 137–138 , 355 , Map 25)

Diagnosis.— Hypatopa nex is similar to H. cladis in facies but differs from the latter by having a more broadly rounded uncus; a less upturned ventral margin of the ventral part of the valva; and a smaller proximal flange of the dorsal part of the valva. H. nex also has a protuberant median lobe of the ventroposterior margin of the gnathos; an anellus that is transversely setose near midlength, with a large apical barblike process that are lacking in H. cladis .

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Outer surface of labial palpus dark brown or brown with white scales along apical margins of segments 1–2; inner surface paler. Antenna pale brown. Proboscis pale brownish gray.

Thorax: Tegula and mesonotum with scales brownish gray tipped with white. Legs dark brown intermixed with brown, with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 355 ): Length 5.0–6.0 mm (n = 3), white intermixed with pale-brown scales on basal 1/3, brown intermixed with brown scales tipped with pale brown and white on apical 2/3; submedian fascia faint; cell with three brown spots, one near middle, two on apical end along crossvein. Undersurface brownish gray. Hindwing: Translucent brownish gray gradually darkening to apex.

Abdomen: Male genitalia ( Figs. 137–138 ): Uncus narrow basally, slightly constricted near midlength, narrowly rounded apically, slightly downcurved, sparsely setose, shorter than width of anal opening. Gnathos, confluent with tegumen, lateral arms thin, directed anteriorly, fused mesially, forming widened median lobe. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part nearly parallelsided to 2/3, abruptly narrowed apically, forming elongate, inwardly curved, spinelike process; process planate on inner surface; ventral margin upturned from slightly beyond base, forming narrow fold, abruptly terminating about 2/3 near slightly widened, setose lobe at base of spinelike process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; basal ridge of digitate process abruptly curved ventrally fusing with proximal flange; flange, disclike process with microtrichiate surface on basal 1/2, setose on apical 1/2. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; sclerite of phallus, shallowly sigmoid-shaped; anellus with single apical barblike process, setose near midlength with pair of setae along margin near base. Female Genitalia: Unknown.

Distribution (Map 25). Hypatopa nex is known from three collecting sites in northwestern Costa Rica along the western most part of the Cordillera de Guanacaste.

Etymology. The specific epithet nex is from the Latin for, a violent death.
