Costarina cruces , new species ( Figures 483–493 )

TYPES: Male holotype and female allotype from wet cloud-forest litter taken at an elevation of 1400 m at a site 5 km southwest of the Estación Biológica Las Cruces , 8°47′13″N, 82°59′13″W, Puntarenas, Costa Rica (June 22, 1998; R. Anderson), deposited in AMNH (PBI_OON 51286) .

DIAGNOSIS: Males resemble those of C. ubicki (cf. figs. 494–504) in having the distal embolar prong bent at a 90° angle, but lack a triangular projection on the distal edge of that prong (figs. 483–488); females also resemble those of C. ubicki but have posteriorly narrower posterior genitalic elements (figs. 492, 493).

MALE (PBI_OON 51286, figs. 483–488): Total length 2.46. Endite ventral process long, with curved tip; dorsal process with angular, medially directed projection. Femur II p0-0-1; tibia I v4-4-2; metatarsus I v2-2-2. Embolus proximal prong short, narrow; distal prong with retrolaterally directed projection (N = 3).

FEMALE (PBI_OON 49244, figs. 489–493): Total length 2.60. Spination typical. Genital atrium short, wide, filled with protuberant sclerotization, anterior genitalic process visible through cuticle as very narrow sclerite (N = 5).

DISTRIBUTION: Southeastern Puntarenas.
