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 ).

Description

Male

See Marques & Buckup (1993: 129, figs 13–14, as T. pretiosa ).

Female

See Marques & Buckup (1993: 128, figs 7–8).

Remark

Based on the large number of male and female specimens collected together, we suggest that Tekellina pretiosa is a junior synonym of Tekellina guaiba .

Distribution

Previously known from the state of Amazonas and Rio Grande do Sul, Brazil. Herein newly recorded from the states of Amazonas, Bahia, São Paulo and Rio Grande do Sul, Brazil ( Fig. 11 ).
