Costarina watina: Platnick and Dupérré, 2011: 50 .

DIAGNOSIS: Males resemble those of C. maritza (cf. figs. 34–44) but have a shorter distal embolar prong and a bifid proximal embolar prong (figs. 232–237); females have a small, almost pentagonal rounded genital atrium (figs. 241, 242), and usually have fully fused ventral scuta (figs. 239, 240).

MALE (PBI_OON 51236, figs. 232–237): Total length 2.02. Endite dorsal process elongated, abruptly bent at level of tip of ventral process, tip directed anteriorly. Femur II p0-0-2, r0-1-0; tibia I v4-4-2; metatarsus I v2-2-2. Embolus distal prong relatively narrow, abruptly bent; proximal prong V-shaped in ventral view (N = 3).

FEMALE (PBI_OON 51236, figs. 238–242): Total length 2.53. Femur II r0-1-1. Genital atrium oval triangle, anterior genitalic process very narrow as seen through cuticle, apodemes short, directed almost laterally (N = 5).
