Diagnosis.— Pigritia faux is similar to P. haha in facies but differs from the latter in having a wider mesially emarginate gnathos; a shorter, a more inwardly curved apical process of the ventral part of the valva; a shorter digitate process of the dorsal part of the valva; a more protracted basal part of the valva; and a shorter phallus and sclerite of the phallus. P. f a u x also has a bandlike juxta; and a setose anellus that are lacking in P. haha .

Description.—Head: Scales on vertex and frontoclypeus pale grayish brown tipped with paler grayish brown. Labial palpus in male extending to or slightly above antennal base [female unknown]; outer surface of labial palpus with segments 1–2 brown intermixed with pale-brown scales along apical margins, segment 3 brown with a shortened pale-brown apical part. Antenna pale grayish brown. Proboscis pale grayish brown.

Thorax: Tegula and mesonotum pale grayish brown. Legs grayish brown intermixed with pale grayish-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 411 ): Length 3.5–4.9 mm (n = 19), pale grayish brown intermixed with few grayish-brown scales, with no distinct markings. Undersurface brown. Venation ( Fig. 47 ) with M2 and M3 stalked in series from a common point with CuA1 on distoposterior part of cell; cubital veins divergent from bases with CuA1 straight and CuA2 acutely curved from middle. Hindwing: Translucent pale brown gradually darkening to apex. Venation ( Fig. 47 ) with cell closed; cubitus 3-branched with all veins arising submarginally.

Abdomen: Male genitalia ( Figs. 239–240 ): Uncus reduced to a slightly raised apical lobe. Gnathos anteriorly directed thin band; ventroposterior margin mesially protuberant, forming emarginate lobe. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part slightly longer than wide, broadened basally, angular apicoventrally, widening to middle, narrowing to base of inwardly curved, apical process; process hinged basally, planate on inner surface, with protuberant setose ridge at base; dorsal part with apical portion of costa extending dorsally, forming straight, setose, digitate process; process shorter than apical process of ventral part; basal ridge of digitate process extending ventrally, separate from proximal flange; flange subellipsoid, narrow basally, gradually widening to base of apical process, slightly protuberant, supplanting outer part of inner surface to margin; mesial surface sparsely microtrichiate, marginal surface densely setose; margin entire. Juxta bandlike. Vinculum shallowly semicircular. Phallus and sclerite of phallus shorter than valva; phallus bulbous basally; sclerite of phallus shallowly undulate, acutely curved basally, slightly widened apically; anellus slightly widened beyond base, gradually narrowing to a rounded apex, setose on basal 1/2. Female Genitalia: Unknown.

Distribution (Map 53). Pigritia faux is known from five collecting sites along the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet faux is derived from the Latin meaning or referring, to the throat.
