Costarina aguirre , new species ( Figures 188–198 )

TYPE: Male holotype from Cerro Nara, Quepos, Aguirre , Puntarenas, Costa Rica (May 28, 2010; M. Solis), deposited in INBIO (PBI_OON 51270) .

DIAGNOSIS: Males resemble those of C. monte (cf. figs. 67–77) in having a large, wide distal embolar prong, but have a much shorter proximal prong (figs. 188–193); the females here tentatively matched with the male have two closely spaced, triangular lobes extending posteriorly from the posterior margin of the genital atrium (figs. 197, 198).

MALE (PBI_OON 51270, figs. 188–193): Total length 2.00. Both processes on endite relatively narrow, long. Femur II p0-0-1; metatarsus I v2-2-2. Embolus proximal prong short, triangular in ventral view; distal prong with doubly incised tip (N = 1).

FEMALE (PBI_OON 51274, figs. 194–198): Total length 2.03. Spination typical. Genital atrium with two rounded, closely spaced apodemal lobes extending posteriorly from posterior margin (N = 2).
