Diagnosis.— Pigritia stips shares with the North American P. arizonella (Dietz) an absence of the uncus; a hinged apical process of the ventral part of the valva; a setose dorsal part of the proximal flange, juxtaposed by a setose ridge beneath; and a divided juxta. It differs from the latter by having the labial palpus extending above the vertex; a wider gnathos; a smaller apical process of the ventral part of the valva; a broader basal part of the ventral part of the valva; a shorter digitate process of the dorsal part of the valva; a longer phallus; and a shallowly curved sclerite of the phallus.

Description.—Head: Scales on vertex and frontoclypeus brownish-gray scales tipped with pale brownish gray or pale brown in rubbed specimens. Labial palpus extending slightly above vertex in male [female unknown]; outer surface of segments 1–2 brown intermixed with pale brown scales along apical margins, terminal segment pale brown, inner surface pale brown. Antenna pale brown. Proboscis pale brown.

Thorax: Tegula and mesonotum with brownish-gray scales tipped with pale brownish gray or pale brown in rubbed specimens. Legs grayish brown intermixed with pale grayish-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 415 ): Length 4.5–5.0 mm (n = 3), grayish brown intermixed with pale grayish-brown scales and grayish-brown scales tipped with pale grayish brown; cell with two grayish-brown spots near apical end along crossvein. Undersurface brown. Hindwing: Translucent pale grayish brown.

Abdomen: Male genitalia ( Figs. 247–248 ): Uncus absent. Gnathos, anteriorly directed thin band; ventroposterior margin entire. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, broadly rounded to middle, abruptly narrowed, extending to dilated base of apical process; process hinged basally, straight throughout most of length, acutely curved apically, setose on outer margin, planate on inner surface, with protuberant setose ridge at base; dorsal part with apical portion of costa extending dorsally, forming short, setose, and straight, digitate process; process shorter than apical process of ventral part; basal ridge of digitate process extending ventrally, separate from proximal flange; flange, subellipsoid, slightly narrowed apically, sparsely microtrichiate on flattened dorsal part, separated by narrow fissure adjacent to densely setose sigmoid-shaped ridge; margin entire. Juxta divided, forming two angular plates. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus bulbous basally, sclerite of phallus shallowly undulate, narrowly bifurcate apically; anellus slightly narrowed from widened base, rounded apically, setose on basal 4/5. Female Genitalia: Unknown.

Distribution (Map 55). Pigritia ululae is known from two collecting sites north of the Cordillera Central in north-central Costa Rica.

Etymology. The specific epithet ululae is derived from the Latin ulula meaning, an owl.
