Costarina concinna (Chickering) ( Figures 417–427 View FIGURES 417–427 )

Dysderina concinna Chickering, 1968: 9 , figs. 13–19 (male holotype from Volcán , Chiriquí, Panama, in MCZ; examined).

Dysderina potena Chickering, 1968: 24 , figs. 50–52 (female holotype from Volcán , Chiriquí, Panama, in MCZ; examined). NEW SYNONYMY.

Costarina concinna: Platnick and Dupérré, 2011: 50 .

Costarina potena: Platnick and Dupérré, 2011: 50 .

DIAGNOSIS: T his appears to be a southern vicariant of the widespread species C. plena (cf. figs. 1–11); the two species have been collected together only in the Reserva Biológica Hitoy Cerere in Limón. Males have a much larger, wider, more rectangular proximal embolar prong (figs. 417–422) and females have a larger, less triangular genital atrium (figs. 426, 427).

MALE (PBI_ OON 29753 View Materials , figs. 417–422): Total length 2.22. Endite ventral process very short, tip heavily sclerotized; dorsal process long, narrow, tip widely separated from tip of ventral process. Femur II p0-0-2, r1-1-0; metatarsus I v2-2-2. Embolus proximal prong wide, flag shaped; distal prong long, bent only at apex (N = 2).

FEMALE (PBI_ OON 29815 View Materials , figs. 423–427): Total length 2.38. Spination typical. Genital atrium relatively large, almost completely filled with protuberant sclerotization, anterior margin rebordered (N = 4).

DISTRIBUTION: Southern Limón, southeastern Puntarenas, and northern Panama.

SYNONYMY: Chickering collected at Volcán, Chiriquí, Panama, from Aug. 9–14, 1950, and described five species of Dysderina based on specimens he captured there: three based exclusively on males, and two based exclusively on females. He recognized that the female holotype of D. potena “appears to be closely related to D. plena ,” so it is surprising that he did not match that specimen with the males of D. concinna , which closely resemble the males of C. plena . Both sexes have since been taken together in Panama.
