Diagnosis: Four dark saddles, more or less equally distributed along the head and body. Relatively small, dark pigmented dorsal fins, each with a white distal streak. Large pectoral fins.

This species has an average length of 56 cm (22 in) and can reach a maximum length of 61 cm (24 in). This shark was described in 2005, making it one of the most recently described of its genus.
