description: Pigritia dido Adamski, new species
(Figs. 46, 237–238, 274, 410, Map 52)
Diagnosis.— Pigritia dido possesses the following unique combination of characters: a short labial palpus; uncus and gnathos present; a basally hinged and acutely curved apical process of the ventral part of the valva; a large, subcircular proximal flange supplanting nearly 1/2 of the inner surface of the valva; and a phallus and sclerite of phallus that are shorter than the valva. Many of these characters are shared with other Pigrita, however, no other congener possesses this combination.
Description.—Head: Scales on vertex and frontoclypeus grayish brown tipped with white. Labial palpus diminutive in male, extending about 1/2 distance between ventral margin of frontoclypeus and antennal base from a depression on ventral part of frontoclypeus; labial palpus extending upwards to a point slightly below antennal bases in female. Outer and inner surfaces of labial palpus with segments 1–2 grayish brown intermixed with white scales along apical margins, segment 3 grayish brown with a short, white apical part. Antennal scape with scales grayish brown tipped with white, pecten grayish brown, flagellum brown basally gradually brightening apically. Proboscis with grayish-brown scales tipped with white.
Thorax: Tegula with basal 1/3 with grayish-brown scales tipped with white; apical 2/3 with pale grayish-brown scales tipped with white; mesonotum with basal 1/5 with grayish-brown scales tipped with white; apical 4/5 with pale grayish-brown scales tipped with white. Legs with grayish-brown scales tipped with white intermixed with white scales near midsegments and apical margins of all segments and tarsomeres. Forewing (Fig. 410): Length 4.0–5.5 mm (n = 19), grayish brown scales tipped with white intermixed with grayish-brown and white scales; base gradually darkening to about 1/3, adjacent to a narrow, transversely-curved, white band; apical 2/3 darker than base; cell with three faint spots, one near middle, two on apical end along crossvein; marginal spots faint or absent. Undersurface brown. Venation (Fig. 46) with M2, M3, and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 and CuA2 straight. Hindwing: Translucent pale brown gradually darkening to apex. Venation (Fig. 46) with anterior part of cell closed, posterior part of crossvein weak; cubitus 3-branched with all veins arising submarginally.
Abdomen: Male genitalia (Figs. 237–238): Uncus near parallelsided throughout most of length, narrowly rounded apically, straight, sparsely setose, shorter than width of anal opening. Gnathos, anteriorly directed thin band; ventroposterior margin entire. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part broadly rounded basally, widening to middle, narrowing to base of large, inwardly curved, apical process; apical process hinged, acutely curved inward near 2/3, 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; process widened at base, gradually narrowing apically; basal ridge of digitate process absent; proximal flange, subcircular, large, supplanting nearly 1/2 inner surface of valva, sparsely microtrichiate on dorsal 1/2, densely setose on ventral 1/2, with two parallel rows of setae along dorsal margin; apical margin entire. Juxta divided, forming two large triangular plates. Vinculum semicircular. Phallus and sclerite of phallus shorter than valva, phallus straight, parallelsided; sclerite of phallus acutely curved basally; anellus parallelsided from a wide base, broadly rounded apically, emarginate mesially, setose. Female Genitalia (Fig. 274): Apophyses posteriores 2 1/ 2X longer than apophyses anteriores. Ostium bursae within membrane near to posterior end of seventh segment, between to globose lateral lobes; each lobe with circular microtrichiate area on apical end; narrow duct connecting ductus seminalis and anterior part of ductus bursae from shared point; eighth tergum with darkly pigmented mesial longitudinal streak. Posterior margin of seventh sternum straight. Ductus bursae 1 1/ 5X longer than apophyses posteriores; with narrow, spinulate band on anterior 1/2. Corpus bursae ovoid, spinulate; signum, thin spinate process, arising from an angular base.

Distribution (Map 52). Pigritia dido is known from one collecting site on the western most part of the Cordillera de Talamanca in south-central Costa Rica.
Etymology. The specific epithet dido is chosen in honor of Dido, founder of Carthage, daughter of Belus of Tyre, and sister of Pygmalion.
