Karyological evidence for a cryptic species of piranha within Serrasalmus rhombeus (Characidae, Serrasalminae) in the Amazon
Cytogenetic data obtained for Serrasalmus rhombeus revealed two cytotypes (cyto type 1 and cytotype 2) at four sampling sites. Cytotype 1 consists of 2n = 60, 20M + 24SM + 6ST + 10A and was detected in specimens from Negro River (Anavilhanas Islands), Solimões River (Camaleão Lake), confluence of Ne...
