Hypatopa joniella Adamski , new species

( Figs. 37 , 187–188 , 380 , Map 37)

Diagnosis.— Hypatopa joniella is similar to H. edax in facies but differs from the latter by having a narrower base of the uncus; and a less acutely curved digitate process of the dorsal part of valva. H. joniella also has an entire ventroposterior margin of the gnathos; a slightly curved apical process of ventral part of valva; a deeply serrate lateral margin of the proximal flange of the dorsal part of the valva; a widely bulbous base of the phallus; and a nearly truncate apex of the anellus that are lacking in H. edax .

Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margin of segment 2 and apical portion of segment 3, inner surface pale brown. Antennal scape brown intermixed with few pale-brown scales along apical margin, pecten grayish brown, flagellum gray. Proboscis pale brownish gray.

Thorax: Tegula with basal 1/5 brown, apical 4/5 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. 380 ): Length 9.5–10.2 mm (n = 7), pale brown intermixed with reddish-brown and brown scales; cell with three spots, one near middle, two on apical end along crossvein; marginal spots connected forming a crenulate pattern. Undersurface brown. Venation ( Fig. 37 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; M2 closer to M1 than to M3; cubital veins divergent from bases with CuA1 straight and CuA2 acutely curved basally. Hindwing: Translucent pale brown slightly darkening to apex. Venation ( Fig. 37 ) with cubitus 4-branched; M2 arising from point slightly beyond distoposterior part of cell and M3 and CuA1 branched near 1/2.

Abdomen: Male genitalia ( Figs. 187–188 ): Uncus gradually narrowed from single-tiered base, gradually narrowed, laterally flattened, and acutely curved apically, sparsely setose, shorter than width of anal opening. Gnathos, thin band, confluent with tegumen, ventroposterior margin entire, with a slightly protuberant, broadly rounded mesial lobe. Sockets of tergal setae not extending to midlength of tegumen. Valva divided; ventral part projected inwardly, gradually widened before midlength, narrowing apically, forming large, nearly straight apical process; process setose on outer surface, planate on inner surface; ventral margin sparsely setose, slightly upturned beyond middle, forming narrow fold to near setose lobe; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process broadly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsal ridge of proximal flange; flange subelliptical, densely microtrichiate, setose submarginally; ventrolateral margin deeply serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, bulbous basally, sclerite of phallus acutely curved near base; anellus gradually widened from base, nearly truncate apically, setose laterally. Female Genitalia: Unknown.

Distribution (Map 37). Hypatopa joniella is known from one collecting site on the central part of the Cordillera de Talamanca in southeastern Costa Rica.

Etymology. The specific epithet joniella is chosen in honor of Jon David Adamski, my son, who collected this species with me on a very cold evening.
