Pseudokoleps akainae Adamski , new species

( Figs. 53–54 , 313 , Map 1)

Diagnosis.— Pseudokoleps is monotypic, and the single included species, P. akainae , can be distinguished from other Blastobasinae by the features listed in the description and diagnosis of the genus.

Description.—Head: Vertex and frontoclypeus with brown scales tipped with pale brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margins of segments 1–2, inner surface of labial palpus pale brown. Antennal scape brown intermixed with few pale-brown scales, pecten pale brown, flagellum gray; flagellum with basal 1/2 brown, apical 1/2 pale brown; first flagellomere unmodified in male. Proboscis brown.

Thorax: Tegula and mesonotum with basal 1/2 brown, apical 1/2 pale brown. Legs brown intermixed with pale-brown scales near midtibia and apical margins of tibia and tarsomeres. Forewing ( Fig. 313 ): Length 3.9–4.8 mm (n = 3), brownish orange intermixed with few brown scales; submedian fascia faint; cell with three faint spots, one spot near middle, two spots on apical end along crossvein. Undersurface brown. Hindwing: Translucent brown.

Abdomen: Male genitalia ( Figs. 53–54 ): Uncus gradually narrowing from base, forming rounded apex, setose. Dorsal strut absent. Gnathos absent. Sockets of tergal setae not extending to midlength of tegumen. Distance between articulations of tegumen and vinculum about equal to length of valva. Valva divided, ventral part broadly rounded ventrally, elongate, upturned to middle beneath large subtriangular process of dorsal part, forming rounded fold; apical part developed into bulbous lobe, apically developed into bifurcate process; base of process with densely packed setal cluster on apical margin; bulbous part juxtaposed basally by wartlike setose lobe along margin above marginal fold; dorsal part with apical portion of costa geniculate, extending dorsally, forming apically swollen, setose, digitate process; basal ridge of digitate process extending ventrolaterally fusing with lateral margin of proximal flange; proximal flange subtriangular, widened basally, gradually narrowed apically to pointed apex; proximal flange sparsely setose on basal 1/2, densely setose on apical 1/2. Juxta divided mesially forming two large angular plates. Phallus and sclerite of phallus slightly longer than valva; phallus bulbous basally, slightly curved near middle; sclerite of phallus slightly curved basally, acutely curved at 2/3, gradually widened apically; anellus slightly longer than wide, bearing several shortened mesial setae and three pairs of longer marginal setae. Female Genitalia: Unknown.

Paratypes (2 3): 1 3, same data as for holotype except, “ Dic. 1990 ”, “CRI000, 652943”, “Slide No. 2081”, “USNM 83879”; 1 3, “ Abr. 1995, P. Rios, # 4814”, “CRI002, 336655”, “Slide No. 2094” [1 in INBio, 1 in USNM].

Distribution (Map 1). Pseudokoleps akainae is known from one collecting site along the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet akainae is derived from the Greek akaina meaning thorn or spine, and refers to the downward pointed, thornlike proximal flange of the dorsal part of the valva.
