When this contribution was being reviewed, a third species of this genus was described from the SE Gulf of California : P. robisoni Stenvers & Osborn, 2021 ( Stenvers et al . 2021 ). After comparing our specimens of Paraphronima with this new species, we came to the conclusion that they cannot be assigned to P. robisoni .
