| Scientific Name: | Bathyclarias gigas |
| Species Authority: | Jackson, 1959 |
| Taxonomic Notes: | M. Banda (unpublished) proposes that this species is conspecific with Bathyclarias worthingtoni. The type specimens for both species were examined and could not be distinguished. B. gigas was described by the suprabranchial organ based on the structure which Banda (unpublished) notes is not a valid key character. |
