Its taxonomic placement is uncertain, and it has been alternatively classified as a "clupeoid" or a "salmoniform".^[2][3] The latter classification is now thought to be a wastebasket treatment.^[4] It is currently considered an indeterminate euteleost.^[5]

Morphologically, it is notable for the extreme anterior insertion point of its dorsal fin compared to the anal fin.^[5][6]
