Treatment

Costarina frantzius , new species ( Figures 428–438)

TYPES: Male holotype and female allotype taken at an elevation of 2200 m on Cerro Frantzius, Puntarenas, Costa Rica (Feb. 26–28, 2005; R. Anderson), deposited in INBIO (PBI_ OON 29755 View Materials ) .

DIAGNOSIS: Males of this relatively large species can easily be recognized by the abruptly bent, translucent tip of the distal embolar prong (figs. 428–433), females by the overhanging anterior margin of the genital atrium and the very short apodemes (figs. 437, 438).

MALE (PBI_ OON 29755 View Materials , figs. 428–433): Total length 2.38. Endite ventral process long, narrow; dorsal process with long, arched anteromedially directed extension. Femora: I r0-1-1; II p0-0-1; tibia I v4-4-2; metatarsus I v2-2-2. Embolus proximal prong gradually tapering to fine tip; distal prong with abruptly bent prolateral edge (N = 1).

FEMALE (PBI_ OON 29755 View Materials , figs. 434–438): Total length 2.68. Spination typical. Genital atrium with wide, ventrally protruding sclerotization, anterior margin overhanging protrusion (N = 1).

DISTRIBUTION: Southeastern Puntarenas.
