Hypatopa edax Adamski , new species

( Figs. 185–186 , 379 , Map 37)

Diagnosis.— Hypatopa edax is similar to H. joniella in facies but differs from the latter by having a wider base of the uncus; a more acutely curved apical region of the apical process of ventral part of valva; and a more acutely curved digitate process of dorsal part of valva. H. edax also has a mesially emarginate ventroposterior margin of the gnathos; a serrate lateral margin of proximal flange of the dorsal part of the valva; a slightly bulbous base of the phallus; and anellus that is narrowly rounded apically that are lacking in H. joniella .

Description.—Head: Scales on vertex and frontoclypeus grayish-brown tipped with pale grayish brown. Outer surface of labial palpus brown intermixed with pale grayish-brown scales along apical margins of segments 1–2, inner surface paler. Antennal scape and pecten grayish brown, flagellum grayish brown basally gradually brightening apically. Proboscis pale grayish brown.

Thorax: Tegula and mesonotum grayish brown. Legs grayish brown intermixed with pale grayish-brown scales near midsegments and apical margins of tarsomeres. Forewing ( Fig. 379 ): Length 4.0–4.2 mm (n = 2), pale brown intermixed with pale grayish-brown scales and brown scales; base and submedian fascia brown; cell with three dark-brown spots, one near middle, two on apical end along crossvein. Undersurface grayish brown. Hindwing: Translucent brown gradually darkening to apex.

Abdomen: Male genitalia ( Figs. 185–186 ): Uncus gradually narrowed from broadly rounded base, laterally flattened, acutely curved apically, sparsely setose, shorter than width of anal opening. Gnathos, thin band, confluent with tegumen, ventroposterior margin narrowly emarginate mesially. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part projected inwardly, gradually widened to middle, narrowing apically, forming large, inwardly curved, apical process; process setose on outer surface, planate on inner surface; ventral margin slightly upturned beyond middle, forming narrow fold to near setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; process broadly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsal ridge of proximal flange; flange subelliptical, sparsely microtrichiate on dorsal 1/2, densely setose on ventral 1/2; ventral margin entire, lateral margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus broadly curved near middle, sclerite of phallus broadly curved from slightly beyond middle; anellus gradually narrowed from base, narrowly rounded apically, setose. Female Genitalia: Unknown.

MAP 37. Distribution of Hypatopa edax (●) and H. joniella (˔).

Distribution (Map 37). Hypatopa edax is known from one collecting site on the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet edax is derived from the Latin meaning, greedy.
