, represent a species complex. The pale bands on the tail, considered to be diagnostic character for a single species actually represent a synapomorphy for this monophyletic clade. This premise is reinforced by the presence in this group of some undescribed species, as illustrated in Planquette et al. (1996: 405, 407). A uniquely derived character among the Gymnotiformes, the presence of two clear bands encircling the caudal peduncle throughout its development defines the
