abstract (from publication):
By means of an integrative taxonomic approach, a new species of the H. malabaricus group from the Río de La Plata basin is described. Hoplias argentinensis, new species, is characterized by: 17-19 predorsal scales, 42-43 vertebrae, 20 scales around caudal peduncle, no distinctive brown bands in lower jaw, last series of vertical scales on caudal fin nearly straight, 41-44 lateral-line scales and snout width (18.4-24.9 % of SL). Hoplias argentinensis is discriminated from all other species of the H. malabaricus group by means of traditional characters, landmarksbased morphometrics and genetics. A key to species of the Hoplias malabaricus group is provided.
