Discussion: Cabrera (1961) synonymized haigi under mendocinus , but Pearson (1984) elevated it to a species based on the unique karyotype of 2n=50, FN=66 ( Gallardo, 1991). Although the isozyme study of Gallardo and Palma (1992) found that haigi was paraphyletic, the lack of data from other taxa of the mendocinus complex makes it difficult to evaluate this conclusion. Substantial divergence has been reported between haigi and mendocinus consistent with their recognition at the species level ( Lessa and Cook, 1998; Sage et al., 1986 a).
