The samples ARG-901, ARG-902, ARG-1417, ARG-1432, ARG-1581 and ARG-1637 were collected in spring, ARG-241, ARG- 934, ARG-949 and ARG- 955 in summer, and ARG- 619 in autumn. Six samples are from Mendoza (as is the type series) and five are from provinces south of Mendoza . All specimens of sample ARG-241 (collected in summer, from Mendoza) show a membranous dorsum; most of the specimens of samples ARG-1417 and ARG-1637 have small and isolated sclerites, but other specimens have a membranous dorsum; and the majority of specimens of other samples, independently of provenance and date of capture, present isolated or coalescent bands. In consequence the absence, presence and extension of the sclerotization cannot be explained by season, latitude or altitude.

Quantitative features of the specimens of most samples are within the limits stated in the description of the species. The specimens of sample ARG-619 (autumn specimens, from Neuquen) are exceptional, they are bigger ( Table 1) and also they are more sclerotic and frequently have a dorsal patch.

The previously known distribution of the species is extended south into Chubut province, but it has not yet been collected in Rio Negro, which lies between Neuquen and Chubut ( Fig. 1 View FIGURE 1 ).
