The precise number of Okenia taxa inhabiting the Mediterranean Sea, as well as their general taxonomy, varies according to different specialists. So far, eight valid species have
been reported from the area: Okenia aspersa (Alder & Hancock, 1845), Okenia cupella
(Vogel & Schultz, 1970), Okenia elegans (Leuckart, 1828), Okenia hispanica Valde´s &
Ortea, 1995, Okenia impexa Er. Marcus, 1957, Okenia leachii (Alder & Hancock, 1854),
Okenia mediterranea (Ihering, 1886), and Okenia zoobotryon (Smallwood, 1910). Of these,
only three (O. elegans, O. hispanica, and O. mediterranea) have their type localities in the
Mediterranean Sea, whereas the others were described from different biogeographic areas
and later included in the Mediterranean biota. We carried out a review on Mediterranean
Okenia species through an integrative approach, based on a wide literature search and a
morphological and molecular analysis of available type material and samples collected
recently. The present study confirmed the presence of O. aspersa, O. elegans, O. hispanica, and O. mediterranea in the Mediterranean Sea, although leaving remaining questions
about some of those taxa. The distribution of O. cupella, O. impexa, and O. zoobotryon is
limited to the western Atlantic, and of O. leachii to the eastern Atlantic. All specimens previously identified as O. cupella, O. impexa, and O. zoobotryon by different authors in the Mediterranean Sea were repeatedly misidentified. Thus, we describe Okenia problematica sp. nov. and Okenia longiductis sp. nov., from the “Mediterranean” Okenia cupella/impexa and O. zoobotryon. We also consider here Okenia pusilla Sordi, 1974 a nomen dubium and
include a redescription of the holotype of O. cupella. A molecular phylogeny, including all the sequenced Okenia species, was performed in order to evaluate the evolutionary relationships of the newly described species with the other congeneric taxa
