Hypatopa eos Adamski , new species

( Figs. 215–216 , 394 , Map 44)

Diagnosis.— Hypatopa eos is similar to H. vox in facies but differs from the latter by having a wider gnathos; a wider digitate process of the dorsal part of the valva; longer setae on the apical 1/2 of the proximal flange of the dorsal part of the valva; a smaller phallus; and a shorter sclerite of the phallus. H. eos also has a slightly enlarged base of the phallus; and a deeply emarginate apex of the anellus, with two opposable acuminate lateral arms that are lacking in H. vox .

Description.—Head: Vertex and frontoclypeus pale brown. Outer surface of segments 1–2 of labial palpus brown intermixed with pale-brown scales along apical margins, terminal segment pale brown; inner surface pale brown. Antennal scape and pecten pale brown, flagellum brown [one antenna is missing and one antenna is missing apical part of flagellum]. Proboscis pale brown.

Thorax: Tegula with basal 1/2 brown, apical 1/2 pale brown; mesonotum pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 394 ): Length 3.3 mm (n = 1), pale brown intermixed with yellowish-brown and brown scales [specimen rubbed]. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia ( Figs. 215–216 ): Uncus gradually narrowed from base, straight, narrowly rounded apically, sparsely setose, shorter than width of anal opening. Gnathos wide, confluent with tegumen; ventroposterior margin narrowly emarginate mesially. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, widening to near middle, gradually narrowing to base of inwardly curved, apical process; process acutely curved from middle, setose on outer surface, planate on inner surface; ventral margin sparsely setose, slightly upturned beyond proximal flange, extending to near small, setose marginal 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 subquadrate, protracted ventrolaterally, sparsely microtrichiate on basal 1/2, densely setose (with long setae) on apical 1/2; margin shallowly crenulate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus shorter than valva; phallus straight with wide base; sclerite of phallus shallowly sigmoid-shaped; anellus near parallelsided from base to subapical region, apical part narrowed from subapical region, deeply emarginate apically, forming two opposable, acuminate, lateral processes, setose on apical 1/3. Female Genitalia: Unknown.

Distribution (Map 44): Hypatopa eos is known from one collecting site in north-central Costa Rica north of the Cordillera Central.

Etymology. The specific epithet eos is chosen in honor of Eos , one of the horses of the Sun.
