Costarina chonta , new species ( Figures 337–347 )

TYPE: Male holotype sifted from moss and litter in a bog at an elevation of 2500 m at La Chonta, km 54 on the Inter-American Highway, 9°43′N, 83°56′W, Cartago, Costa Rica (Mar. 26–27, 1999; J. Miller), deposited in USNM (PBI_OON 27839) .

DIAGNOSIS: Males resemble those of C. poas (cf. figs. 111–121), but the heavily sclerotized portion of the distal embolar prong is shorter and more rounded (figs. 337–342); the female here associated resembles that of C. plena (cf. figs. 1–11) but has a small, triangular genital atrium (figs. 346, 347).

MALE (PBI_OON 27839, figs. 337–342): Total length 2.44. Endite ventral process ventrally arched; dorsal process with sharply pointed tip. Femur I r1-1-0. Embolus proximal prong almost obsolete; distal prong with wide translucent flange which is much larger than more heavily sclerotized, retrolateral portion of prong (N = 2).

FEMALE (PBI_OON 29829, figs. 343–347): Total length 2.17. Spination typical. Genital atrium relatively small, almost completely filled with protuberant sclerotization (N = 1).

DISTRIBUTION: Cartago.
