Diagnosis.— Hypatopa texo is similar to H. umbra in facies but differs from the latter by having a wider base of the uncus; a less constricted base of the proximal flange of the dorsal part of the valva; and a narrower phallus. H. texo also has an anteriorly directed ventroposterior margin of the gnathos; sockets of tergal setae extending beyond the midlength of the tegumen; a straight apical process of the ventral part of the valva; an acutely curved digitate process of the dorsal part of the valva; a shallowly undulate sclerite of the phallus, apically bifurcate, forming two elongate, broadly curved, convergent processes; and an anellus that is widely emarginate mesially, forming two narrowly rounded, setose lateral lobes that are lacking in H. umbra .

Description.—Head: Vertex and frontoclypeus grayish brown. Outer surface of labial palpus with segment 1 brown, segment 2 brown intermixed with pale-brown scales along apical margin, segment 3 pale brown intermixed with few brown scales; inner surface pale brown. Antennal scape brown intermixed with pale-brown scales, pecten brown, flagellum gray. Proboscis pale brown.

Thorax: Tegula brown or with basal 2/3 brown, apical 1/3 pale brown; mesonotum brown. Legs dark brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 398 ): Length 4.5–5.7 mm (n = 19), dark brown intermixed with brown and pale-brown scales; basal 1/3 brown except costa dark brown to 2/3; two pale-brown markings arising from posterior margin, one obliquely arched spot adjacent to basal 1/3, one subcircular spot proximal to tornus; two dark-brown spots at apical 1/3, one pale-brown spot near tornus, one subapical along costa; marginal spots coalescing forming irregularly shaped crenulations. Undersurface brown. Venation ( Fig. 42 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 nearly straight and CuA2 broadly curved. Hindwing: Translucent pale brown. Venation ( Fig. 42 ) with cubitus 4-branched; M2 arising 1/2 distance between distoposterior part of cell and branching point of M3 and CuA1.

Abdomen: Male genitalia ( Figs. 223–224 ): Uncus gradually narrowed from wide base, slightly constricted near middle, slightly curved apically, sparsely setose, longer than width of anal opening. Gnathos narrow, anteriorly directed band, confluent with tegumen; ventroposterior margin emarginate mesially. Sockets of tergal setae extending beyond midlength of tegumen. Valva divided; ventral part basally protracting inwardly, widening to middle, gradually narrowing to base of inwardly curved, apical process; process acutely curved from middle, setose on outer surface, planate on inner surface; ventral margin setose, with a setose ridge at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process geniculate from beyond base; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange subquadrate, protracted ventrolaterally, with broadly rounded apical margin, sparsely microtrichiate on basal 1/2, setose on apical 1/2; margin serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, bulbous basally; sclerite of phallus shallowly undulate, apically bifurcate, forming two elongate, broadly curved, convergent processes; anellus widely emarginate mesially, forming two porrect, narrowly rounded, setose, lateral lobes. Female Genitalia ( Fig. 267 ): Apophyses posteriores about 2 1/ 2X longer than apophyses anteriores. Ostium bursae within membrane posterior to seventh segment; posterior margin of seventh sternum straight. Inception of ductus seminalis arising beyond anterior margin of seventh sternum; ductus bursae slightly greater than 2X longer than apophyses posteriores; slightly spinulate on anterior 1/5. Corpus bursae ovoid, spinulate; signum absent.

Distribution (Map 46): Hypatopa texo is known from one collecting site on the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet texo is derived from the Latin textilis meaning, a woven textile.
