Costarina espavel , new species ( Figures 348–358 )

TYPES: Male holotype and male paratype from dry litter taken at an elevation of 200 m on the Espavel trail in the Reserva Biológica Hitoy Cerere , Limón, Costa Rica (Mar. 28, 2002; P. T homas), deposited in INBIO (PBI_OON 29747) .

DIAGNOSIS: Males resemble those of C. obtina (cf. figs. 439–449) in having a translucent flange on the distal embolar prong, but have a longer proximal embolar prong (figs. 348–353); females have fully fused ventral scuta, a relatively large, semicircular genital atrium, and a basally widened anterior genitalic process (figs. 355–358).

MALE (PBI_OON 29747, figs. 348–353): Total length 1.72. Both processes on endite relatively long, narrow. Femur I r0-1-1; tibiae: I v4-4-2; II v4-4-0; metatarsus I v2-2-2. Embolus proximal prong long, narrow, straight; distal prong with translucent flange along proximal edge (N = 8).

FEMALE (PBI_OON 51266, figs. 354–358): Total length 2.66. Spination typical. Genital atrium relatively large, oval, posterior margin anteriorly produced at midline (N = 8).
