Costarina carrillo , new species ( Figures 210–220)

TYPES: Male holotype, female allotype, and female paratype taken at an elevation of 1100 m on a nature trail along a cloud-forest/rainforest transect in the Parque Nacional Braulio Carrillo, San José , Costa Rica (Apr. 28–30, 1983; D. Ubick), deposited in CAS (PBI_ OON 51235 ) .

DIAGNOSIS: Males closely resemble those of C. elena (cf. figs. 56–66) in having an enlarged, distally flared distal embolar prong with a long, narrow basal extension and a basally widened proximal embolar prong, but have a rounded tip on the distal prong (figs. 210–215); females resemble those of C. viejo (cf. figs. 133–143) and C. cerere (cf. figs. 406–416) in having fully fused ventral scuta and a pair of round sclerotizations at the sides of the genital atrium, but the posterior genitalic elements lack the posteromedian lobe found in those species (figs. 217–220).

MALE (PBI_ OON 51235 , figs. 210–215): Total length 2.35. Both processes on endite short, narrow. Femora: I r1-1-0; II p0-0-1; metatarsus I v2-2-2. Embolus distal prong long, anterior margin subdistally excavated; proximal prong gradually narrowing throughout its length (N = 1).

FEMALE (PBI_ OON 51235 , figs. 216–220): Total length 2.75. Spination typical. Genital atrium relatively large, with sclerotizations visible through anterolateral corners (N = 2).

DISTRIBUTION: San José.
