Costarina ubicki , new species ( Figures 494–504 )

TYPES: Male holotype and female allotype from moist tropical forest litter taken at an elevation of 100 m at a site 3 km south of Palmar Norte , Puntarenas, Costa Rica (May 24, 1987; D. Ubick), deposited in CAS (PBI_OON 51289) .

ETYMOLOGY: T he specific name is a patronym in honor of the collector of the types, Darrell Ubick, of the California Academy of Sciences .

DIAGNOSIS: T his species seems closest to C. cruces (cf. figs. 483–493), but males have a much shorter distal embolar prong with a triangular projection on its distal margin (figs. 494– 499) and females have posteriorly wider posterior genitalic elements (figs. 503, 504).

MALE (PBI_OON 51289, figs. 494–499): Total length 1.89. Endite ventral process wide, short; dorsal process with arched tip. Femur II p0-0-2; tibia I v4-4-2; metatarsus I v2-2-2. Embolus proximal prong reduced to short lobe; distal prong with straight, prolaterally directed extension (N = 11).

FEMALE (PBI_OON 51289, figs. 500–504): Total length 2.13. Spination typical. Genital atrium with relatively large posterior margin (N = 2).

DISTRIBUTION: Southern Puntarenas, including the Osa Peninsula.
