Costarina gemelo , new species ( Figures 450–460 )

TYPES: Male holotype and female allotype from humus taken at an elevation of 1670 m in the Estación Pittier, 4 km southwest of Cerro Gemelo, 9.025663°N, 82.962695°W, Puntarenas, Costa Rica (July 4, 1995; C. Víquez), deposited in INBIO (PBI_OON 29741) .

DIAGNOSIS: Males can be recognized by the three long, parallel projections on the embolus (figs. 450–455), females resemble those of C. pittier (cf. figs. 461–471) and C. palmar (cf. figs. 505–515) in having long apodemes, a distally narrow anterior genitalic process, and a short postepigastric scutum, but have a larger genital atrium (figs. 459, 460).

MALE (PBI_OON 29741, figs. 450–456): Total length 2.18. Endite ventral process relatively wide; distal process with long, arched, medially directed extension. Femur I p0-0-2, r0-1-1; tibia I v4-4-2; metatarsus I v2-2-2. Embolus proximal prong and both arms of bifid distal prong nearly parallel (N = 1).

FEMALE (PBI_OON 29741, figs. 457–460): Total length 2.40. Spination typical. Genital atrium with long apodemal extensions (N = 1).

DISTRIBUTION: Southeastern Puntarenas.
