Costarina murphyorum , new species ( Figures 78–88 )

TYPES: Male holotype, female allotype, and female paratype taken from roadside scrub at an elevation of 1500 m at Monteverde, Puntarenas, Costa Rica (Aug. 24, 1983; J., F. Murphy), deposited in AMNH (PBI_OON 36787) .

ETYMOLOGY: T he specific name is a patronym in honor of John and Frances Murphy, who collected the only known specimens of this species.

MALE (PBI_OON 36787, figs. 78–83): Total length 1.97. Endite ventral process basally wide, distally heavily sclerotized; dorsal process long, arched. Femur II p0-0-2, r0-1-0. Embolus proximal prong arched; distal prong deeply bifid (N = 6).

FEMALE (PBI_OON 36787, figs. 84–88): Total length 2.12. Spination typical. Genital atrium wide, posterior margin transverse, with recurved corners (N = 3).
