Aplysia parvula was long seen as a circumtropical sea hare species, but Golestani et al. (2019) restricted the name A. parvula to the population from tropical waters in the northwest Atlantic, while resurrecting A. elongata, A. japonica, A. atromarginata, and A. nigrocincta for populations from the Indo-Pacific and describing the new species A. ghanimii and A. hooveri for populations from the eastern Pacific. The type locality of Aplysia parvula is Saint Vincent, Lesser Antilles.
