description: Hypatopa acus Adamski, new species
(Figs. 151–152, 362, Map 28)
Diagnosis.— Hypatopa acus is similar to H. crux in facies but differs from the latter by having a slightly wider gnathos; a shorter apical process of the ventral part of the valva that is acutely curved inwardly; and a smaller proximal flange with a margin that is shallowly crenulate. H. acus also has a ventroposterior margin of the gnathos that is not directed anteriorly; and a vesica with two large barbless cornuti that are lacking in H. crux.
Description.—Head: Vertex and frontoclypeus pale brown. Outer surface of labial palpus pale brown intermixed with brown scales, inner surface paler. Antenna pale brown. Proboscis pale brown.
Thorax: Tegula with basal 1/2 brown, apical 1/2 pale brown; mesonotun brown intermixed with pale-brown scales. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of tarsomeres. Forewing (Fig. 362): Length 4.4–4.7 mm (n = 2), pale brown intermixed with brownish-orange scales and few brown scales; cell with three faint brown spots, one near middle, two on apical end along crossvein. Undersurface brown. Hindwing: Translucent brown, gradually darkening to apex.
Abdomen: Male genitalia (Figs. 151–152): Uncus gradually narrowed from single-tiered base, acutely curved downwards from subapical region, sparsely setose, apex laterally flattened, shorter than width of anal opening. Gnathos wide, confluent with tegumen, ventroposterior margin slightly emarginate mesially. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, gradually narrowed apically from widened middle, forming short, inwardly curved, spinelike process; process acutely curved from 2/3, planate on inner surface; ventral margin setose along a slightly upturned part, extending to abruptly dilated margin near 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 dorsal ridge of proximal flange; flange ellipsoid, bearing densely packed microtrichiae on upper 1/2 and densely packed setae on lower 1/2; margin shallowly crenulate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, sclerite of phallus acutely curved near 2/3 and at base; vesica with 2 large subequal cornuti, anellus setose. Female Genitalia: Unknown.

Distribution (Map 28). Hypatopa acus is known from three collecting sites; one along the western most part of the Cordillera de Guanacaste, one along the eastern most part of the Cordillera de Talamanca near the border of Panama, and one along the southeastern Pacific coastline on the Osa Peninsula.
Etymology. The specific epithet acus is derived from the Latin for, a needle.
