Costarina pittier , new species ( Figures 461–471 )

TYPES: Male holotype and male paratype 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 (8577, PBI_OON 29780) .

DIAGNOSIS: Males of this dark-bodied species resemble those of C. reventazon (cf. figs. 301–307) in having a long embolus without obvious prongs, but differ in having the embolus abruptly bent (figs. 461–466); females resemble those of C. gemelo (cf. figs. 450–460) and C. palmar (cf. figs. 505–515) in having long apodemes and a short postepigastric scutum, but have large, heavily sclerotized posterior genitalic elements (figs. 470, 471).

MALE (PBI_OON 29780, figs. 461–466): Total length 2.09. Both processes on endite wide at base, heavily sclerotized. Femur I r0-1-0. Embolus with single prong, bent prolaterally at about two-thirds its length, with recurved tip (N = 20).

FEMALE (PBI_OON 10032, figs. 467–471): Total length 2.60. Tibia II v4-4-2. Genital atrium, with short, rounded apodemal lobes at posterolateral corners (N = 8).

DISTRIBUTION: Abundant in southern Puntarenas, including the Osa Peninsula.
