(Figs. 10–15)
Oligoxystre argentinense; Costa et al., 2000 (misidentification).
Material examined — Holotype: Male, IBSP 9491, Uruguay, Lavalleja, Águas Blancas; F. Pérez­Miles leg., 22.XI.1993. Paratypes: Female, IBSP 9507, Uruguay, Lavalleja, Águas Blancas; F. Pérez­Miles leg., 22.XI.1993. Male, MCN 4658, Brazil, Rio Grande do Sul, Rio Grande; C. J. Becker leg., 17.IX.1976; Female, MCN 15746, Brazil, Rio Grande do Sul, Rio Grande; A. Lise leg., 2.IX.1986.
Distribution — Brazil, Rio Grande do Sul, Rio Grande, 1ɗ (MCN 2336), 1juvenile (MCN 14232); Pelotas, 1ɗ (AMNH­ no number). Uruguay, Maldonado 1ɗ (MHNM 1247); Lavalleja, Águas Blancas 2Ψ (MHNM­no number); Lavalleja 3ɗ (MHNM­no number).
Etymology — named after the type locality.
Diagnosis — Males differ from those of other species by the tibial spur having two short straight spines on the apical region of the external branch (Fig. 10). Females differ from those of C. petropolium by the termini of their spermathecae being straight, rather than inward facing (Figs. 11–12). No morphological characters are known to distinguish female C. uruguayense from C. argentinense. For now, these two species can only be distinguished by their zoogeographical distribution (C. uruguayense occurs in southern Rio Grande do Sul State in Brazil and Uruguay).
