Taonius is a small genus of glass squid. Although it comprises only three recognised species, it has been suggested there may be as many as five species. Taonius borealis is found in the North Pacific Ocean and Taonius pavo is found in the Atlantic and possibly the south-western Indian Ocean.
Some teuthologists dispute Voss's synonymy of Belonella with Taonius.
