description: Pigritia haha Adamski, new species
(Figs. 48, 241–242, 412, Map 53)
Diagnosis.— Pigritia haha is similar to P. faux in facies but differs from the latter in having a narrower gnathos; a longer, less inwardly curved apical process of the ventral part of the valva; a less protracted basal part of the ventral part of the valva; a longer digitate process of the dorsal part of the valva; and a longer phallus and sclerite of the phallus. Pigritia haha also has a divided juxta; an apically bifurcate sclerite of the phallus; and an anellus formed from two large, lateral lobes with deeply crenulate margins that are lacking in P. f a u x.
Description.—Head: Vertex and frontoclypeus pale brown. Labial palpus in male extending to or slightly beyond level of vertex [female unknown]; outer surface brown intermixed with pale-brown scales along apical margins of segments 1–2 and on apical part of terminal segment; inner surface pale brown. Antennal scape and pecten pale brown, flagellum brownish gray basally gradually brightening apically. Proboscis pale brown.
Thorax: Tegula and mesonotum with grayish-brown scales tipped with 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. 412): Length 3.9–4.9 mm (n = 4), pale brown intermixed with grayish-brown scales or brownish-orange scales; submedian fascia incomplete or absent; cell with two spots on apical end along crossvein. Undersurface brown. Venation (Fig. 48) 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 broadly curved. Hindwing: Translucent pale brown gradually darkening to apex. Venation (Fig. 48) with cell open; basal 4/5 of M1 weak; cubitus 3-branched with all veins arising submarginally.
Abdomen: Male genitalia (Figs. 241–242): Uncus absent. Gnathos, anteriorly directed thin band. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part broadly rounded basoventrally, widening to middle, narrowing to base of apical process; process hinged basally, straight throughout length except, acutely curved apically, planate on inner surface, with protuberant setose ridge at base; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process straight, pointed inwardly; basal ridge of digitate process extending ventrally, fusing dorsally with proximal flange; flange subellipsoid, slightly protuberant, smooth on basal 1/2, densely microtrichiate on apical 1/2, densely setose marginally; margin entire. Juxta divided, forming two large subtriangular plates, supplanting most membrane. Vinculum shallowly semicircular. Phallus and sclerite of phallus longer than valva; phallus bulbous basally; sclerite of phallus shallowly curved basally, apically bifurcate; anellus, forming two large, lateral lobes with deeply crenulate lateral margins, setae absent. Female Genitalia: Unknown.

Distribution (Map 53). Pigritia haha is known from one collecting site on the northern part of the Caribbean coast in northeastern Costa Rica.
Etymology. The specific epithet haha is derived from the Latin ha, hahae, or hahahae, meaning, an exclamation of joy or amusement.
