Costarina obtina (Chickering) ( Figures 439–449)

Dysderina obtina Chickering, 1968: 21 , figs. 42–45 (male holotype from Volcán , Chiriquí, Panama, in MCZ; examined).

Costarina obtina: Platnick and Dupérré, 2011: 50 .

DIAGNOSIS: Males of this dark-bodied species resemble those of C. espavel (cf. figs. 348– 358) in having a translucent flange on the distal embolar prong, but have a shorter proximal embolar prong (figs. 439–444); females have heavily sclerotized, arched posterior genitalic elements (figs. 448, 449).

MALE (PBI_ OON 29756 View Materials , figs. 439–444): Total length 2.10. Endite ventral process relatively wide; distal process with arched, medially directed extension. Femora: I r0-1-1; II p0-0-1; tibia I v4-4-2; metatarsus I v2-2-2. Embolus proximal prong excavated on distal side; distal prong with translucent, relatively narrow proximal flange (N = 13).

FEMALE (PBI_ OON 29756 View Materials , figs. 445–449): Total length 2.12. Spination typical. Genital atrium almost rectangular, followed posteriorly by medially divided sclerotization (N = 4).

DISTRIBUTION: Southeastern Puntarenas.
