 Type. P. bonariensis – unknown to us; P. vicinus s. st r. holotype male, Museo Argentino de Ciencias Naturales “Bernadino Rivadavia,” Buenos Aires; P. vicinus argentinus, holotype male, Museo Argentino de Ciencias Naturales “Bernadino Rivadavia,” Buenos Aires.   
 Diagnosis. General – Pronotum strongly granulate posteromedially. Posterolateral pronotal ridge (Fig. 40, cf. Fig. 37) short, not extending to lateral pronotal fossa. Metasternal shield completely coarsely punctured (as in Fig. 19); anterior portion of metasternum finely granulate laterally, smooth medially. Carinulate margins of striae 2-4 gently undulate such that width of stria at narrowings is at least threefourths of that at widest points (Fig. 15); carinulae simple, rarely tuberculate. Interstriae completely covered by large, round granules. Dorsal color usually shade of green or yellowish green. Length 21-35 mm.   
 Male (Fig. 42-44) – Pronotal concavity with dorsally inclined spiniform process on each side below prominence (Fig. 43). Dorsal prominence narrow, scoop-shaped, width of saddle less than length (Fig. 42). Apical process of parameres acute in profile.   
 Female (Fig. 40-41) – Pronotal concavity lacking lateral spines. Protarsi lacking.   
 Specimens examined – 222.   
 Distribution. Cerrado and Chaco provinces of Chacoan subregion (Fig. 28).

 Comments. This species largely replaces C. ensifer in the chiquitano, cerrado and chacoan habitats of eastern Bolivia and surrounding portions of Argentina, Paraguay and Brazil.   
 We here correct the record concerning female protarsi in C. bonariensis; contrary to Edmonds (1972), they are absent in this species. Consequently, medium-sized females and smaller males are virtually indistinguishable externally.
