Principal component scores from a correlation matrix of morphological and meristic data for two karyotypic forms of the Gymnotus carapo species complex from the Eastern Amazon. The first three principal components represent 39.9%, 67.7%, and 90.1% of cumulative variance respectively. In all combinations of these four axes the two karyotypes exhibited substantial overlap. The following meristic counts were eliminated from this analysis due to a lack of variance: P1R, BAN, SAL, APS, CEP (see Table 2 for abbreviations).
