( Figs. 231–232 , 402 , Map 48)

Diagnosis.— Hypatopa rudis is similar to H. musa in facies but differs from the latter by having a slightly longer uncus; and a basally narrower digitate process of the dorsal part of the valva. Hypatopa rudis also has a protuberant and widely emarginate mesial lobe of the ventroposterior margin of the gnathos; a laterally curved apical process of the ventral part of the valva; a sparsely setose proximal flange of the dorsal part of the valva; and a narrowly truncate apex of the anellus, with two pairs of setae on lateral margins of the subapical region and two pairs of setae on the lateral margins near base that are lacking in H. musa .

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

Thorax: Tegula and mesonotum with brownish-gray scales tipped with pale brownish gray. Legs brownish gray intermixed with pale brownish-gray scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 402 ): Length 4.6 mm (n = 1), with pale brownish-gray scales tipped with white intermixed with brownish-gray scales; area between costa and CuP brownish gray; submedian fascia incomplete, faint. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia ( Figs. 231–232 ): Uncus slightly narrowed from base, narrowly rounded apically, straight, sparsely setose, shorter than width of anal opening. Gnathos, narrow band, confluent with tegumen; ventroposterior margin entire (gnathos contorted during dissection and not visible). Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part broadly rounded basally, widening to middle, narrowing to base of outwardly curved, apical process; process widened apically from narrow basal stem, setose on outer surface, planate on inner surface, with a protuberant setose ridge at base; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; ridge of digitate process extending ventrally fusing with dorsal ridge of proximal flange; flange subcircular, shallowly protuberant, sparsely microtrichiate, with small setal cluster near middle of ventral margin and row of setae along lateral margin. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus bulbous basally; sclerite of phallus curved at 2/3 and along base; anellus gradually narrowed from base, narrowly truncate apically, with two pairs of setae along lateral margins of subapical region and two pairs of setae along lateral margins near base. Female Genitalia: Unknown.

Distribution (Map 48). Hypatopa rudis is known from one collecting site in northwestern Costa Rica in a dryforest region southwest of the Cordillera de Guanacaste.

Etymology. The specific epithet rudis is derived from the Latin meaning, a small stick.
