Diagnosis.— Hypatopa plebis is similar to H. dolo and H. cyane in facies but differs from them by having sexually dimorphic lengths of the labial palpus (longer in female); a larger base of the uncus; a more shallow mesial emargination of the ventroposterior margin of the gnathos; and a more oblique lateral margin of the proximal flange of the dorsal part of the valva. Hypatopa plebis also has an anellus that is broadly constricted near the middle that are lacking in H. dolo and H. cyane .

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Labial palpus short in male, not extending beyond midlength of frontoclypeus, longer in female. Outer and inner surfaces of labial palpus with scales brownish gray tipped with pale brownish gray. Antennal scape with scales brownish gray tipped with pale brownish gray, pecten pale brownish gray, flagellum brownish gray. Proboscis brownish gray.

Thorax: Tegula and mesonotum brownish gray. Legs brownish gray intermixed with pale brownish-gray scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 368 ): Length 4.1–5.5 mm (n = 12), brownish gray intermixed with pale brownish-gray scales scattered throughout middle area from base to crossvein of cell; cell with three spots, one near middle, two on apical end along crossvein; marginal spots absent. Undersurface brown. Venation ( Fig. 32 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases; CuA1 nearly straight and CuA2 broadly curved. Hindwing: Translucent pale brown. Venation ( Fig. 32 ) with cubitus 4-branched with M2 arising from distoposterior part of cell and M3 and CuA1 branching near 1/5.

Abdomen: Male genitalia ( Figs. 163–164 ): Uncus narrowed from broadly rounded base, narrowly rounded apically, straight, sparsely setose, shorter than width of anal opening. Gnathos, narrow band, confluent with tegumen, ventroposterior margin slightly protuberant mesially forming narrowly emarginate lobe. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, somewhat parallelsided, gradually narrowing to base of inwardly curved, spinelike apical process; process acutely curved from 1/3, setose on basal part of outer surface, planate on inner surface; ventral margin greatly curved upwards, forming wide fold beneath apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process abruptly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange subquadrilateral (with opposite sides near equal and near parallel), bearing densely packed microtrichiae on upper 1/2, setose on ventral 1/2, intermixed with few spinules along ventrolateral margin; ventral and ventrolateral margin entire, setose dorsolaterally. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva, both broadly curved from middle; anellus wide basally, broadly constricted near middle, gradually narrowed from slightly widened subapical region, forming narrowly rounded apex, setose on apical part, with single, trisetose row on lateral margins. Female Genitalia ( Fig. 263 ): Apophyses posteriores about 2 1/ 2X longer than apophyses anteriores. Ostium bursae within membrane, slightly posterior to seventh segment. Posterior margin of seventh sternum straight. Ductus bursae about 1 1/ 2X longer than apophyses posteriores; with two rows of imbricate platelets within anterior 1/2, gradually becoming sparser posteriorly. Inception of ductus seminalis arising from ductus bursae anterior to posterior margin of seventh sternum. Corpus bursae ovoid, sparsely spinulate; signum absent.

Distribution (Map 31). Hypatopa plebis is known from one collecting site in northwestern Costa Rica on the western most part of the Cordillera de Guanacaste.

Etymology. The specific epithet plebis is derived from the Latin plebs meaning, the people.
