FIGURE 52 | Predorsal region of trunk in dorsal view in CS specimens of Aspidoras poecilus, showing the following morphological variation: nuchal plate (A) separated from the posterior process of the parieto-supraoccipital by the first dorsolateral body plate (UNT 6249, 30.9 mm SL), (B) separated from the posterior process of the parieto-supraoccipital by the first dorsolateral body plate, with platelets on the region between them, and (C) nearly contacting the posterior process of the parieto-supraoccipital. Dotted lines 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, pso: parieto-supraoccipital. Scale bars = 1 mm.
