This species of bamboo shark is distinguished by its unique combination of white lines/spots along the margin of the large, dark saddles on the back, scattered white spots particularly on the upper side, and a row of 7-8 well-defined, horizontally-ovate, dark spots on the lower side between the abdomen and caudal-fin base (Ref. 74956).

Western Pacific: apparently confined to Cenderawasih Bay, Papua Barat Province, Indonesia.
Occurs on shoreline fringing reefs or shallow patch reefs; observed at night at depths between 2-4 m, usually seen resting on the bottom, occasionally observed while slowly swimming or 'walking' over the bottom with the pectoral and pelvic fins. Probably sedentary during daylight hours, sheltering under rocky outcrops or tabular corals, typical for other family members (Ref. 74956).
