[2] The genus Tomiyamichthys belongs to the family Gobiidae which the 5th edition of Fishes of the World places in the order Gobiiformes.

The specific name, russus, means "red", an allusion to the pinkish colour of this fish's body.

[1] This is a greyish species of shrimp goby which has a dark bar underneath its eye, golden spots, a brown vertical blotch on the operculum and four large brown spots along its flanks which extend onto the lower back.
