Costarina jimenez , new species ( Figures 538–548 )

TYPES: Male holotype, female allotype, male paratype, and female paratype taken by sifting leaf litter at an elevation of 100 m in a tropical moist forest 8 km west of Puerto Jiménez, Puntarenas, Costa Rica (May 19, 1987; D. Ubick), deposited in CAS (PBI_OON 51295) .

DIAGNOSIS: Males can be recognized by the enlarged proximal embolar prong, which is much longer than the distal prong (figs. 538–543), females by the tiny genital atrium and weakly sclerotized, triangular posterior genitalic elements (figs. 547, 548).

MALE (PBI_OON 51295, figs. 538–543): Total length 1.85. Endite ventral process sharply pointed; dorsal process basally widened. Femur II p0-0-1. Embolus proximal prong greatly enlarged, longer than distal prong (N = 10).

FEMALE (PBI_OON 51295, figs. 544–548): Total length 2.26. Spination typical. Genital atrium short, wide, oval, filled with protuberant sclerotization, anterior, posterior margins rebordered (N = 7).

DISTRIBUTION: Southern Puntarenas, including the Osa Peninsula.
