Costarina rafael , new species ( Figures 144–154 )

TYPE: Male holotype taken from leaf litter near a stream at an elevation of 5600 feet at a site 3.2 km north of the junctions of Routes 126(9) and 140, and 0.3 km east on the road to San Rafael , Heredia, Costa Rica (Mar. 18, 1991; L. Herman), deposited in AMNH (PBI_OON 85) .

DIAGNOSIS: Males resemble those of C. san (cf. figs. 268–278) in having a short proximal embolar prong that parallels the much larger, squared distal prong, but the proximal prong is narrower (figs. 144–149); females have a pair of lateral extensions on the anterior margin of the genital atrium (fig. 153).

MALE (PBI_ OON 51214 , figs. 144–149): Total length 2.01. Endite ventral process wide, short; dorsal process narrow, long. Femora: I r0-1-1; II p0-0-1. Embolus distal prong squared, prolateral portion translucent; proximal prong short, narrow (N = 9).

FEMALE (PBI_ OON 51214 , figs. 150–154): Total length 2.23. Spination typical. Genital atrium wide, with sinuous posterior margin, anterior margin continued anteriorly as conspicuous sclerotized band (N = 10).
