Costarina cima , new species ( Figures 45–55 )

TYPE: Male holotype from the summit (cima) of Volcán Cacao, Guanacaste, Costa Rica (July 27, 2010; C. Víquez), deposited in INBIO (PBI_OON 21114) .

DIAGNOSIS: Males resemble those of C. poas (cf. figs. 111–121) in having a broad, flat embolus, which has the proximal and distal prongs fused for much of their length, but have a more rectangular proximal prong (figs. 45–50); females have very thick, heavily sclerotized anterior margin of the genital atrium (figs. 54, 55).

MALE (PBI_OON 21114, figs. 45–50): Total length 2.02. Endite ventral process basally widened; distal process narrow. Femora: I r0-1-1; II p0-0-2; metatarsus II v2-1p-1r. Embolus distal and proximal prongs fused for most of their length, producing wide structure with translucent prolateral portion (N = 36).

FEMALE (PBI_OON 88, figs. 51–55): Total length 2.24. Femur II r0-0-0. Genital atrium very short, with broad, heavily sclerotized anterior margin (N = 18).

DISTRIBUTION: Abundant in northern Costa Rica (Guanacaste, Alajuela, and northern Puntarenas) .
