Hypatopa texla Adamski , new species

( Figs. 193–194 , 383 , Map 39)

Diagnosis.— Hypatopa texla is similar to H. verax in facies but differs from the latter by having a wider and acutely curved apical process of the ventral part of the valva; and a wider digitate process of the dorsal part of the valva. H. texla also has an entire ventroposterior margin of the gnathos; a bulbous base of the phallus; an irregularly curved sclerite of phallus; and an apically truncate anellus that are lacking in H. verax .

MAP 39. Distribution of Hypatopa texla (●) and H. verax (˔).

Description.—Head: Vertex and frontoclypeus pale brown intermixed with grayish-brown scales tipped with pale grayish brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margins of segments 1–2, terminal segment pale brown; inner surface pale brown. Antennal scape brown intermixed with few pale-brown scales, pecten pale brown, flagellum pale gray; first flagellomere unmodfied in male. Proboscis pale brown.

Thorax: Tegula brown on basal 1/2, pale brown on apical 1/2; mesonotum pale brown. Legs brown intermixed with pale-brown scales near midsegments and apical margins of tarsomeres [many scales missing]. Forewing ( Fig. 383 ): Length 7.6 mm (n = 1), pale brown intermixed with few brown scales; cell with three faint brown spots, one near middle, two on apical end along crossvein. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia ( Figs. 193–194 ): Uncus gradually narrowed from base, parallelsided to subapical region, acutely curved and narrowly rounded apically, sparsely setose, about equal in length to width of anal opening. Gnathos, thin band, confluent with tegumen; ventroposterior margin entire. Sockets of tergal setae not extending to midlength of tegumen. Valva divided; ventral part slightly projecting inwardly at base, gradually widened near middle, narrowing apically, forming large, inwardly curved apical process; process acutely curved near 1/3, setose on outer surface, planate on inner surface; ventral margin slightly upturned before middle, forming narrow fold to near setose lobe at base of apical process; dorsal part with a widened costa extending dorsally, forming setose digitate process; process slightly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange semicircular, densely microtrichiate on mesial surface, densely setose on surrounding submarginal surface; margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, bulbous basally, sclerite of phallus irregularly curved throughout length; anellus gradually widened from base, apically truncate, setose. Female Genitalia: Unknown.

Distribution (Map 39). Hypatopa texla is known from one collecting site on the Cordillera de Talamanca in southeastern Costa Rica.

Etymology. The specific epithet texla is derived from the Latin tela meaning, that which is woven.
