With a rounded pectoral fin disc and a long, projecting snout, T. acutirostra resembles (and was historically confused with) the smaller pale-edged stingray (T. zugei).

[1] Prior to being scientifically described, T. acutirostra has been confused for T. zugei; the two species have been confounded by various authors since at least Jordan and Fowler's 1903 review of Japanese elasmobranchs.

[2] In 1988, Kiyonori Nishida and Kazuhiro Nakaya published a study of the T. zugei species complex with a description of T. acutirostra, in the Japanese Journal of Ichthyology.

[2] Telatrygon acutirostra is known from off southern Japan and in the East China Sea at a depth of 53–142 m (174–466 ft), though there is also a possible record of this species from the Gulf of Guayaquil off Ecuador.

[3] Telatrygon acutirostra likely forms part of coastal bottom trawl and set net fishery catches operating off Japan and elsewhere, though specific utilization data is required.

The International Union for Conservation of Nature (IUCN) has assessed this species as Vulnerable, as it would be highly susceptible to increasing fishing pressure given its possibly limited geographic distribution.
