| Abstract |
The genus Tanaella is revised and the generic diagnosis redefined. Both genders of the type species, Tanaella unguicillata and T. ochracea are redescribed. Two new species, T. prolixcauda and T. mclellandi, are described from deep-sea localities in the Gulf of Mexico. Male Tanaella possess fully functional mouthparts resembling, but not identical to, those of the females. Distribution and ecological information are given for all species in the genus and a key to Tanaella is also given. |
