Table 4. Morphometries of Cyanocharax tipiaia, new species. Standard length is expressed in mm; other measurements through head length are percentages of standard length; the last four entries are percentages ofhead length. All specimens are from laguna dos Patos drainage. Described ranges include measurements of the holotype MCP 30741 and following paratypes: MCP 22712.
