Description
Table 2. Meristic and morphological characters applied to the identification (following Dyer, 2006) of 45 individuals from Lake Pellegrini. Results from mtDNA analysis are compared with identification based on taxonomic key: origin of first dorsal fin over posterior half of pelvic fin (O. hatcheri) or anterior to anus and posterior to pelvic fin (O. bonariensis), number of dorsal scale rows between lateral lines>12 (O. hatcheri) or <11(O. bonariensis); number of gill rakes on the lower arm of first branchial arch, 21-27 (O. hatcheri) or>30 (32-38) (O. bonariensis); upper jaw prognathous (O. hatcheri) or lower jaw prognathous in large specimens (O. bonariensis). N: number of specimens. In bold, the presumptive hybrids individuals identified on meristic and morphological characters, those are highlighted with * in Fig. 3).
