Costarina azul View in CoL , new species ( Figures 155–165 View FIGURES 155–165 )

TYPES: Male holotype and male paratype taken by sifting leaf litter in a cloud forest at an elevation of 1500 m at a site 1 km north of Montaña Azul, Heredia, Costa Rica (May 7–8, 1987; D. Ubick), deposited in CAS (PBI_OON 51215) .

DIAGNOSIS: Males resemble those of C. cruz (cf. figs. 326–336) in having the distal embolar prong deeply bifid, producing a distinctive appearance, with three parallel, prolaterally directed flanges, but the teeth on the embolar base are much shorter and the middle flange has a much narrower base and a blunter tip (figs. 155–160); females also have fully fused ventral scuta but have a much larger genital atrium with the posterior margin expanded near the midline (figs. 162–165).

MALE (PBI_OON 51215, figs. 155–160): Total length 2.38. Endite ventral process wide, short; dorsal process narrow, short. Femora: I r1-1-0; II p0-0-2. Embolus distal prong deeply bifid, distal portion more heavily sclerotized; proximal prong long, narrow, sharply bent at half its length (N = 6).

FEMALE (PBI_OON 27674, figs. 161–165): Total length 2.38. Spination typical. Posterior margin of genital atrium medially expanded into wide, short triangle (N = 4).
