Treatment

Costarina alturas View in CoL , new species ( Figures 472–482 View FIGURES 472–482 )

TYPES: Male holotype, female allotype, and female paratype from litter taken along a montane/cloud-forest transect at an elevation of 1520 m in the Estación Biológica Las Alturas, 2 km northeast of Alturas, 8°56′56″N, 82°50′01″W, Puntarenas, Costa Rica (June 20, 1998; R. Anderson), deposited in AMNH (PBI_OON 49241) GoogleMaps .

DIAGNOSIS: Males resemble those of C. isidro (cf. figs. 254–260) in having a long, narrow, ventrally arched proximal embolar prong but have a narrower tip on the distal embolar prong (figs. 472–477); females also resemble those of C. isidro (cf. figs. 567–571) but have shorter posterior genitalic elements (figs. 479–482).

MALE (PBI_OON 49241, figs. 472–477): Total length 2.20. Endite ventral process relatively long, narrow; dorsal process with angular, anteromedially directed projection. Femur I r0-1-1; tibia I v4-4-2; metatarsus I v2-2-2. Embolus proximal prong long, narrow, scythe-shaped in ventral view; distal prong with serrated tip (N = 7).

FEMALE (PBI_OON 49241, figs. 478–482): Total length 2.42. Spination typical. Genital atrium short, wide, with W-shaped posterior margin (N = 9).
