Maximum total length reported as 31.4 cm (Ref. 3202, 81251) seems based on Ref. 82238 (holotype size), but is more likely 21.4 cm based on the holotype picture on the MNHN collection website, which agrees to the maximum standard length reported and observed (T.

It usually has dark brown or black flanks marbled with, irregularly shaped, light brown markings, but this colour pattern may be less conspicuous in light-coloured specimens (Ref. 126042).
