Aesthetic Identification: The South China catshark is dark in color with no obvious markings. The gill slits are short. The widest is much less than the eye length. There are short medial projections on the gill septa. The first dorsal fin is about half the size of the second. The first dorsal fin originates over the last quarter of the pelvic fin bases. The pectoral and pelvic fins are well separated. The anal fin is large and angular. It is separated from the tail by a small notch.

Biology and Reproduction: Unknown but possibly oviparous.
