Costarina junio , new species ( Figures 290–300 )

TYPES: Male holotype and male paratype from wet cloud-forest litter taken an at elevation of 2900 m at a site near km 71 of the Inter-American Highway near Tres de Junio, 9°37′44″N, 83°50′13″W, on the San José / Cartago border, Costa Rica (June 23, 1999; R. Anderson), deposited in AMNH (PBI_OON 51242) .

DIAGNOSIS: Males and females have not been taken together, and are only tentatively matched here. Males resemble those of species like C. poas (cf. figs. 111–121), C. rafael (cf. figs. 144–154), and C. cuerici (cf. figs. 279–289) in having greatly enlarged, flange-shaped distal embolar prongs, but have a longer tip on the proximal embolar prong (figs. 290–295); females resemble those of C. rafael but have fully fused ventral scuta (figs. 297–300).

MALE (PBI_OON 51242, figs. 290–295): Total length 2.43. Both processes on endite with narrow, curved, heavily sclerotized tips. Femur II p0-0-1. Embolus proximal prong long, narrow; distal prong enlarged, with narrow, translucent flange on prolateral side (N = 4).

FEMALE (PBI_OON 37016, figs. 296–300): Total length 2.35. Spination typical. Posterior margin of genital atrium recurved, apodemes enlarged, triangular (N = 1).

DISTRIBUTION: San José and adjacent Cartago.
