Chlopsis bidentatus is an eel in the family Chlopsidae.

[2] It is a deep-water, marine eel which is known from New Caledonia and Fiji, in the western central Pacific Ocean.

It typically dwells at a depth range of 300–503 m. Males can reach a maximum total length of 16.7 cm.

[1] The specific epithet, bidentatus, is a combination of the Latin words bi and dentatus, meaning "two-toothed".

It refers to the vomerine dentition of the species, in two anterior, biserial rows, which is described as a distinctive feature.
