Discussion: Several different karyotypes have been reported including 2n=36, FN=64; 2n=42, FN=64 and 2n=44-45, FN=68 (Anderson et al., 1987). Anderson et al. (1987) suggested that three or more cryptic species with different karyotypes may be included within this taxon, one of which ( goodfellowi) was elevated to specific rank (Anderson, 1997). Anderson et al. (1987) considered nattereri a subspecies of boliviensis but Woods (1993) recognized it as a species without comment.
