Treatment

Costarina semibio , new species ( Figures 527–537 View FIGURES 527–537 )

TYPES: Male holotype, female allotype, and two male paratypes taken at an elevation of 130 m at a site 13 km south-southwest of Puerto Jiménez , 8.40667°N, 83.32833°W, Puntarenas, Costa Rica (Mar. 10, 2008; J. Longino), deposited in MCZ (PBI_ OON 38101 View Materials ) GoogleMaps .

ETYMOLOGY: T he specific name is an arbitrary combination of letters.

DIAGNOSIS: Males resemble those of C. obtina (cf. figs. 439–449) but have a longer distal embolar prong (figs. 527–532); females have a wider anterior genitalic process and shorter, more widely separated apodemes (figs. 536, 537).

MALE (PBI_ OON 38101 View Materials , figs. 527–532): Total length 1.97. Endite ventral process long, sharply pointed; dorsal process strongly arched. Femur I r0-1-1; tibia I v4-4-2; metatarsus I v2-2-2. Embolus with both prongs sinuous, distal prong with tip directed distally (N = 11).

FEMALE (PBI_ OON 38101 View Materials , figs. 533–537): Total length 2.00. Spination typical. Genital atrium with pair of widely separated, posterolateral apodemal lobes (N = 12).
