Table 1. Sampling localities, basins, latitude, longitude, mean summer air temperature 1961-1990 (Temp, data from Servicio Meteorológico Nacional, Argentina, www.smn.gov.ar), species identification, and SL of Odontesthes specimens used in this study. All river drainages flow to the Atlantic, unless otherwise noted (Pacific). OB: O. bonariensis, OH: O. hatcheri, Hy: presumptive hybrids, showing key characters of both species; CA: Cluster Analysis; GMA: Geometric Morphometrics Analysis; N: number of specimens. In bold, differences between key, genetic, and morphological criteria. Presumptive hybrids were highlighted as * in Fig. 3 and bold characters in Table 2.| Sampling locality and river basin | Latitude (S) Longitude (W) | Temp (ºC) | Species based on key characters (N) | Species based on mtDNA (N) | Species based on CA applied to GMA data (N) | SL (cm) (mean and range) |
