“…Although more recently some species of Listrura have been reported to not having dorsal fin (de Pinna & Wosiacki, ; Villa‐Verde, Lima, et al, ), the condition found in most species of Listrura consisting of a small but well‐developed dorsal fin with segmented rays (Landim & Costa, ; de Pinna, ; Villa‐Verde & Costa, ; Villa‐Verde, Ferrer, et al, ; Villa‐Verde Lazzarotto & Lima, ; Villa‐Verde, Lima, et al, ) and that described for glanapterygines are also not comparable. Even among species of Listrura , dorsal fin loss has been considered as independent evolutionary events (Villa‐Verde, Lima, et al, ). In glanapterygines, the anal fin is rudimentary and has minute unsegmented rays and the caudal fin may be rudimentary or not, but fin rays are always unbranched (Costa & Bockmann, ; Myers, ; de Pinna, , ; de Pinna & Kirovsky, ; de Pinna & Zuanon, ; Schaefer et al, ), whereas in Listrura , the anal fin is well‐developed, bearing segmented rays, and the caudal fin is always well developed and contains branched rays (Landim & Costa, ; de Pinna, ; de Pinna & Wosiacki, ; Villa‐Verde & Costa, ; Villa‐Verde, Ferrer, et al, ; Villa‐Verde et al, ; Villa‐Verde, Lima, et al, ), thus again not being comparable character states.…”
