Tekellina pretiosa Marques & Buckup, 1993: 129 , figs 13–14. Syn. nov. Diagnosis Males of Tekellina guaiba resemble those of T. archboldi by the shape of the paracymbium in ventral view ( Figs 2J , 7A–C ), but differ by the longer, more coiled and medially positioned mesal claw of the conductor ( Fig. 7D , 4E ). Females resemble those of T. archboldi by the long shape of the receptacles, but differ by the course of the more angular fertilization ducts and receptacles ( Figs 2L , 4C–D ).
