Hypatopa semela Adamski, new species

(Figs. 183–184, 378, Map 36)

Diagnosis.— Hypatopa semela is similar to H. phoebe in facies but differs from the latter by having a less acutely curved apical process of the ventral part of the valva; and a shorter phallus. H. semela also has an entire margin of proximal flange of the dorsal part of the valva; and a gradually narrowed anellus that is truncate apically, bearing a single seta on each lateral margin near the apical 1/3 that are lacking in H. phoebe.

Description.—Head: Vertex, frontoclypeus pale brown. Outer surface of labial palpus pale brown intermixed with few brown scales, inner surface pale brown. Antennal scape and pecten pale brown, flagellum brown basally gradually brightening apically. Proboscis pale brown.

Thorax: Tegula and mesonotum pale brown. Legs pale brown [hindlegs missing]. Forewing (Fig. 378): Length 8.1 mm (n = 1), pale brown intermixed with few brown scales; cell with three faint brown spots, one near middle, two on apical end along crossvein. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia (Figs. 183–184): Uncus gradually narrowed from widened base, laterally flattened, acutely curved apically, sparsely setose, shorter than width of anal opening. Gnathos wide, confluent with tegumen, ventroposterior margin narrowly emarginate mesially. Sockets of tergal setae extending to midlength of tegumen. Valva divided; ventral part projecting inwardly, gradually widened to about 1/4, narrowing apically, forming large, inwardly curved apical process; process setose on outer surface, planate on inner surface; ventral margin greatly upturned basally, forming widened fold, extending to near setose ridge at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange ellipsoid, sparsely microtrichiate on dorsal 1/3, densely setose on ventral 2/3; margin entire, setose on lateral part. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus nearly straight, sclerite of phallus irregularly undulate throughout length; anellus gradually narrowed from widened base, truncate apically, bearing single seta on each lateral margin near apical 1/3. Female Genitalia: Unknown.

Distribution (Map 36). Hypatopa semela is known from one collecting site on the Cordillera de Tilarán in west-central Costa Rica.

Etymology. The specific epithet semela is chosen in honor of Semela, daughter of Cadmus, mother of Bacchus by Jupiter.
