The Chinese Longnose Dogfish is known only from the South China Sea (holotype was collected at 18°51–47'N, 112°41–33'E) and possibly northwards to Japan, but confirmation is required to determine the full extent of its range (Chu et al. 1984).

The Chinese Longnose Dogfish (Squalus acutirostris) is a very poorly known deepsea shark from the South China Sea. Its taxonomic status needs to be evaluated as it is considered by some to be a junior synonym of the Shortspine Spurdog (Squalus mitsukurii). It is tentatively considered to be a valid species here pending further investigation. The species’ distribution, depth range and habitat are poorly defined, and there is no information available on the impacts of fisheries upon it. It is therefore assessed as Data Deficient.
The specific collection locations of Chinese Longnose Dogfish specimens only include a general region and depth. The threats to this species cannot be identified at this time despite extensive fishing effort in the South China Sea.
