The Two-colored Mussurana individual was identified by its size (TL = 207.5 cm) and uniformly shiny black dorsum, which becomes reddish orange laterally and whitish anteriorly on the venter; towards the tail, the venter becomes gradually grayer. The individual was completely damaged. We used other specimens to help with identification (e.g. ZUFMS-REP00257, REP01417, REP01514, REP01522, REP01555, REP01704).
