Trichiurus cristatus Klunzinger, 1884 Pseudoxymetopon sinensis Chu & Wu, 1962 Tentoriceps is a monotypic genus of cutlassfish, family Trichiuridae, from the Indian and Pacific Oceans.

[2] Tentoriceps cristatus has Indo-West Pacific distribution: it is found in the Indian Ocean (including the Red Sea) and in the Western Pacific Ocean, between the Tasman Sea and southern Japan.

It is a benthopelagic to pelagic species that occurs in coastal waters 30–110 m (98–361 ft) deep, but avoids areas of low salinity.

[2][4] Typical for cutlassfishes, Tentoriceps cristatus has extremely elongate and strongly compressed, ribbon-like body, tapering to a point.

[4] Tentoriceps cristatus is a minor commercial species caught mainly mixed with other cutlassfish in southeast Asian countries.
