Costarina cruz , new species ( Figures 326–336 )

TYPES: Male holotype and female allotype from litter taken at an elevation of 5500 ft near a stream 1 km west of Santa Cruz de Turrialba on Route 230, Cartago, Costa Rica (Mar. 13, 1991; L. Herman), deposited in AMNH (PBI_OON 49230) .

DIAGNOSIS: Males resemble those of C. azul (cf. figs. 155–165) in having the distal embolar prong deeply bifid, producing a distinctive appearance, with three parallel, prolaterally directed flanges, but the teeth on the embolar base are much longer and the middle flange has a much wider base and a narrower tip (figs. 326–331); females also have fully fused ventral scuta but have a much smaller genital atrium (figs. 333–336).

MALE (PBI_OON 49230, figs. 326–331): Total length 2.22. Endite ventral process arched ventrally; dorsal process long, narrow. Femur I r1-1-0; metatarsus I v2-2-2. Embolus proximal prong curving near tip; distal prong deeply bifid, with narrow tip (N = 1).

FEMALE (PBI_OON 49230, figs. 332–336): Total length 2.47. Spination typical. Genital atrium almost completely filled by protuberant sclerotization (N = 1).

DISTRIBUTION: Cartago.
