Distribution — Argetina, Jujuy, Yuto, 1Ψ ( MACN 6427); Córdoba: Capilla del Monte, 1Ψ ( MACN 6425); Calamuchita, 1Ψ ( MACN 6428), 1Ψ ( MACN 6432); Valle Hermoso, 1Ψ ( MACN 6429); Cruz del Eje, 1ɗ ( MACN 6526). San Luis: El Volcán, 1juvenile and 1Ψ ( MACN 6426), 1Ψ ( MACN 6430). Tucumán: Tucumán, 1Ψ ( MACN 6431). Chile, Curico, 1Ψ ( MHNV 005) Museo de Historia Natural de Valparaiso — Chile ( Legéndre & Calderón, 1984).

Diagnosis — Males may be recognized by having the tibial spur formed by a weakly developed process with a large apical spine ( Figs. 16–17 ). Females differ from those of C. petropolium by the termini of their spermathecae being straight, rather than inward facing ( Fig. 20 ) and from those of C. uruguayense only by zoogeographical distribution ( C. argentinense occurs in the mid­central of Argentina and Chile).
