(Figs. 235–236, 409, Map 52)
Diagnosis.— Pigritia sedis shares with the North American P. f i d e l l a (Dietz) a shortened labial palpus; a hinged apical process of the ventral part of the valva; a narrow digital process of the dorsal part of the valva; an elongate and densely setose proximal flange; a divided juxta, lacking an uncus and gnathos. Pigritia sedis differs by having a more inwardly curved apical process of the ventral part of the valva; a more densely setose proximal flange of the dorsal part of the valva; a shorter phallus and sclerite of phallus; and a setose, barblike process originating from the subapical region of the anellus.

Description.—Head: Vertex and frontoclypeus pale brown. Labial palpus short in male, extending about 1/2 distance between ventral margin of frontoclypeus and antennal base [female unknown]. Outer and inner surfaces pale brown. Antennal scape pale brown intermixed with few brown scales, pecten pale brown, flagellum pale brown. Proboscis pale brown.
Thorax: Tegula and mesonotum pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing (Fig. 409): Length 4.6 mm (n = 1), pale brown intermixed with few brownish-orange scales and brown scales; cell with two brown spots on apical end along crossvein. Undersurface brown. Hindwing: Translucent pale brown gradually darkening to apex.
Abdomen: Male genitalia (Figs. 235–236): Uncus reduced to slightly pointed lobe. Gnathos absent. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part broadened basally, angular apicoventrally, widening to middle, narrowing to base of inwardly curved, apical process; process hinged basally, setose on outer surface, planate on inner surface, with protuberant setose ridge at base; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; basal ridge of digitate process separate from proximal flange; flange large, subsemicircular, densely setose, supplanting most inner surface; margin entire. Juxta divided, forming two large triangular plates. Vinculum shallowly semicircular. Phallus and sclerite of phallus longer than valva, both broadly curved from middle; anellus near parallelsided throughout length, apically truncate, bearing laterally protuberant, setose, barblike process from subapical region. Female Genitalia: Unknown.

Distribution (Map 52). Pigritia sedis is known from one collecting site in central Costa Rica north of the Cordillera Central.
Etymology. The specific epithet sedis is derived from the Latin sedes meaning, seat.
