Integrative taxonomy suggests hidden diversity within the fishgenus Cyttopsis (Zeiformes, Parazenidae)
Nine specimens of Cyttopsis rosea (Zeiformes: Parazenidae) were collected during sci-entific surveys at three different locations in the northeast Atlantic. All nine speci-mens were included in the molecular analysis, adding new cytochrome c oxidasesubunit I sequences to public databases. Of these,...

| Sumario: | Nine specimens of Cyttopsis rosea (Zeiformes: Parazenidae) were collected during sci-entific surveys at three different locations in the northeast Atlantic. All nine speci-mens were included in the molecular analysis, adding new cytochrome c oxidasesubunit I sequences to public databases. Of these, six specimens were retained fordetailed morphological examination. Morphological measurements and counts agreewith previous descriptions and confirm the identification of C. rosea. However,molecular species delimitation analyses suggested cryptic diversity, identifying threemolecular operational taxonomic units, contrary to the current status of a single spe-cies with a orldwide distribution. The integration of classical and molecular taxon-omy proved essential for accurately delimiting and characterizing this species,enhancing our understanding of its intraspecific morphological and molecular variabil-ity. A literature review of the available morphological data of Cyttopsis rosea betweenAtlantic and Pacific specimens showed differences in the caudal peduncle length,number of vertebrae and the number of scales in the lateral line, which could supportthe existence of different species. Based on the resulting data and the available litera-ture, an updated key of the accepted members of the family Parazenidae is provided |
