Hypatopa cotytto Adamski, new species

(Figs. 173–174, 373, Map 34)

Diagnosis.— Hypatopa cotytto is similar to H. caepae in facies but differs from the latter by having a narrower base of the uncus; and a more inwardly curved apical process of the ventral part of the valva. H. cotytto also has a ventroposterior margin of the gnathos projected medioposteriorly, forming a spinelike process; a straight digitate process of the dorsal part of the valva; a subrectangular proximal flange, with the lateral margin shallowly crenulate, bearing a large, laterally projecting spinelike process on apicoventral angle, with densely packed setose cluster at its base; a broadly curved phallus; and setose lateral margins of the anellus that are lacking in H. caepae.

Description.—Head: Scales on vertex and frontoclypeus grayish-brown scales tipped with pale grayish brown. Outer surface of labial palpus grayish brown with pale grayish-brown scales along apical margins of segment 1 and on apical part of segment 3; inner surface paler. Antennal scape with grayish-brown scales tipped with pale grayish brown [pecten missing], flagellum brown. Proboscis pale grayish brown.

Thorax: Tegula and mesonotum agouti patterned, with brown on basal and apical 1/3s, pale brown on middle 1/3. Legs brown intermixed with pale-brown scales near midsegments and apical margins of tarsomeres. Forewing (Fig. 373): Length 4.6 mm (n = 1), pale brown intermixed with brown scales; cell with three brown spots, one spot near middle, two spots on apical end along crossvein; brown marginal spots faint. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia (Figs. 173–174): Uncus slightly constricted from widened base, narrowed from subapical region, forming acuminate apex, nearly straight, sparsely setose, longer than width of anal opening. Gnathos narrow, anteriorly directed band, confluent with tegumen, ventroposterior margin projected medioposteriorly, forming spinelike process. Sockets of tergal setae extending slightly beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, gradually widened to midlength, narrowing to base of pair of subequal, divergent, spinelike apical processes; processes branched from common base; longer process projecting dorsally and inwardly from 1/2, shorter process projecting inwardly to near right angle to larger process; ventral margin entire, with large, rounded setose lobe at base of apical processes; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; basal ridge of digitate process constricted basally, extending ventrally fusing with dorsolateral ridge of proximal flange; flange subrectangular, densely setose, bearing large, laterally projecting spinelike process on apicoventral angle, and densely packed setose cluster at its base; ventral margin entire, lateral margin shallowly crenulate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva, broadly curved near middle, apical part straight; anellus gradually narrowed from base, narrowly rounded apically, setose on lateral margins, with pair of median setae near base. Female Genitalia: Unknown.

MAP 34. Distribution of Hypatopa cotytto (●) and H. lucina (˔).

Distribution (Map 34). Hypatopa cotytto is known from one collecting site in south-central Costa Rica near the mouth of the Golfo de Nicoya.

Etymology. The specific epithet cotytto is chosen in honor of Cotytto, the goddess of unchastity, originally worshipped in Thrace.
