Tab. 4. Meristic counts of Leporinus desmotes and L. jatuncochi summarized as ranges followed by the mean ± 1 standard deviation in parentheses. Single values in a cell indicate invariant counts among the examined specimens for a given species. *Represents data gathered from Ovchynnyk (1971). | L. desmotes (holotype) | L. desmotes | L. jatuncochi (holotype) * | L. jatuncochi |
