FIGURE 76 | Predorsal region of trunk in dorsal view in CS specimens of Aspidoras velites, showing the following morphological variation: (A) absence of dorsal-fin spinelet and bony platelet (LIRP 4435, 23.4 mm SL), and (B) absence of nuchal plate but presenting a reduced and irregular bony platelet on anterior margin of dorsal-fin spine base (black arrow) (MZUSP 73264, paratype, 20.6 mm SL). Dotted lines in (B) indicate the limits of the tip of the posterior process of the parieto-supraoccipital and anterior tip of the nuchal plate. Abbreviations: np: nuchal plate, dfs: dorsal-fin spine, pso: parieto-supraoccipital. Scale bars = 1 mm.
