Costarina meridina (Chickering) View in CoL ( Figures 221–231 View FIGURES 221–231 )

Dysderina meridina Chickering, 1968: 20 , figs. 40, 41 (male holotype from San José View in CoL , Costa Rica, in AMNH; examined).

Costarina meridina: Platnick and Dupérré, 2011: 50 View in CoL .

DIAGNOSIS: T his appears to be a southern vicariant of C. murphyorum (cf. figs. 78–88); males differ in having all parts of the embolus narrower (figs. 221–226), females in having straight posterolateral corners of the genital atrium and narrower paramedian lobes on the posterior genitalic elements (figs. 230, 231).

MALE (PBI_OON 93, figs. 221–226): Total length 1.90. Endite ventral process produced ventrally, heavily sclerotized distally; dorsal process strongly arched. Femur II p0-0-2. Embolus distal prong greatly elongated, with translucent flange at about two-thirds its length; proximal prong distally arched (N = 16).

FEMALE (PBI_OON 93, figs. 227–231): Total length 2.20. Spination typical. Genital atrium short, wide, including transverse sclerotization (N = 21).

DISTRIBUTION: Abundant in San José and adjacent parts of Heredia and Cartago.
