Costarina superplena View in CoL , new species ( Figures 23–33 View FIGURES 23–33 )

TYPE: Male holotype taken in humus at an elevation of 450–550 m at a site 10 km southeast of La Virgen, 10°20′N, 84°05′W, Heredia, Costa Rica (Mar. 17, 2003; R. Anderson), deposited in INBIO (PBI_OON 29750) GoogleMaps .

ETYMOLOGY: T he specific name refers to the similarities between this species and C. plena .

DIAGNOSIS: Specimens of this species can easily be distinguished from those of the similar species C. plena (cf. figs. 1–11) and C. paraplena (cf. figs. 12–22) by their relatively dark coloration; the carapace and abdomen are dark brown rather than orange-brown and the leg femora are distinctly darker than the coxae; the abdomen is narrower than in most other species. Males lack a spinneret scutum and have a thicker, straighter proximal embolar prong (figs. 23–28); females have a wide, short genital atrium, and short, strong apodemes (figs. 32, 33).

MALE (PBI_OON 29750, figs. 23–28): Total length 1.85. Endite ventral and dorsal processes both small, triangular, widely separated. Femur I r0-0-0; tibiae I, II v4-4-0; metatarsus II v2-2-0. Embolus distal prong distally arched, thickened; proximal prong basally enlarged, with straight distal margin (N = 3).

FEMALE (PBI_OON 51223, figs. 29–33): Total length 2.02. Femur II r1-1-0; tibia I v4-4-1p; metatarsus I v2-2- 1p. Genital atrium very wide, short, with gently arched anterior margin (N = 1).
