Costarina viejo View in CoL , new species ( Figures 133–143 View FIGURES 133–143 )

TYPES: Male holotype and female allotype from the Estación Biológica La Selva, Heredia, Costa Rica (Mar. 13, 1987; D. Olson), deposited in MCZ (PBI_OON 37006) .

ETYMOLOGY: T he specific name is a noun in apposition taken from one of the localities (Puerto Viejo de Sarapiquí , Heredia) at which the species occurs.

DIAGNOSIS: Males resemble those of C. upala (cf. figs. 100–110) in having a relatively small, triangular distal embolar prong, but lack a prolaterally directed extension on that prong and have a very narrow proximal embolar prong (figs. 133–138); females resemble those of C. carrillo (cf. figs. 210–220) and C. cerere (cf. figs. 406–416) in having fully fused ventral scuta and a pair of dark sclerotizations at the sides of the genital atrium, but those sclerotizations are ledgelike rather than rounded (figs. 142–143).

MALE (PBI_OON 37006, figs. 133–138): Total length 2.01. Endite ventral process sharply pointed; dorsal process with arched tip. Femora: I r1-1-0; II p0-0-1, r0-1-0; tibiae: I v4-4-2; II v4-4-0; metatarsus I v2-2-2. Embolus distal prong arched, ventral portion translucent; proximal prong narrow, abruptly bent at half its length (N = 23).

FEMALE (PBI_OON 37006, figs. 139–143): Total length 2.22. Femur II p0-0-2, r1-1-0. Genital atrium with pair of dark sclerotizations at lateral margins, anterior genitalic process widened at about half its length (N = 18).

DISTRIBUTION: Abundant in Heredia and Limón.
