Remark: Common names according to Britski et al. (1986) and Ihering (1968). The name <i>L. agassizi</i> was mentioned by Steindachner to refer to <i>L. alexandri</i>. It is possible to conclude because he indicated the same reference of description of <i>L. alexandri</i> (Steindachner, Ichthyol. Beitr. V, p. 106, pl. XV).
