Hypatopa mora Adamski, new species

(Figs. 199–200, 386, Map 40)

Diagnosis.— Hypatopa mora is similar to H. tapadulcea in facies but differs from the latter by having a more acutely curved apical process of the ventral part of the valva; and a more recurved apical part of the sclerite of the phallus. H. mora also has an outwardly curved digitate process of the dorsal part of the valva; and a densely spinulate proximal flange of the dorsal part of the valva that are lacking in H. tapadulcea.

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Outer surface of labial palpus brown intermixed with few pale-brown scales along apical margin of segment 2, inner surface pale brownish gray. Antennal scape brownish gray, pecten brownish gray tipped with pale brownish gray, flagellum gray. Proboscis pale brownish gray.

Thorax: Tegula with basal 4/5 brown, apical 1/5 with brown scales tipped with pale brown; mesonotum with basal 1/2 brown, apical 1/2 pale brown. Legs brown intermixed with pale-brown scales near midsegments and apical margins of tarsomeres [most legs missing]. Forewing (Fig. 386): Length 7.2 mm (n = 1), with basal 1/3 pale brown, apical 2/3 brown intermixed with brown scales tipped with pale brown; apical margin with brown crenulations. Undersurface brown. Hindwing: Translucent pale brown slightly darkening to apex.

Abdomen: Male genitalia (Figs. 199–200): Uncus narrowed from widened base, laterally flattened and acutely curved apically, sparsely setose, slightly longer than width of anal opening. Gnathos attenuate, anteriorly directed band, confluent with tegumen; ventroposterior margin entire. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part projecting inwardly, truncate basally, angular near middle, narrowing apically, forming large, inwardly curved, apical process; process broadly curved inwardly, setose on outer surface, planate on inner surface; ventral margin setose from beyond base, with small setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; process broadly recurved; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange narrowed basally, widening apically, forming subquadrate apical part; proximal flange sparsely microtrichiate basally, densely spinulate and sparsely setose apically. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight beyond bulbous base, sclerite of phallus broadly curved from middle, acutely curved basally, recurved apically; anellus parallelsided from wide base, broadly rounded apically, setose on midregion. Female Genitalia: Unknown.

Distribution (Map 40). Hypatopa mora is known from one collecting site on the Cordillera de Tilarán in westcentral Costa Rica.

Etymology. The specific epithet mora is from the Latin meaning, a delay.
