Rocio is a small genus of cichlid freshwater fishes from southern Mexico and northern Central America.{{cite journal|title=Diversity and evolution of the Middle American cichlid fishes (Teleostei: Cichlidae) with revised classification|author=Říčan, O.|author2=Piálek, L.|author3=Dragová, K.|author4=Novák, J.|name-list-style=amp|journal=Vertebrate Zoology|pages=1–102|volume=66|issue=1|year=2016|doi=10.3897/vz.66.e31534 |doi-access=free |url=http://www.senckenberg.de/files/content/forschung/publikationen/vertebratezoology/vz66-1/01_vertebrate_zoology_66-1_rican_1-102.pdf|access-date=2019-01-25}}
Species
There are currently four recognized species in this genus:{{FishBase genus | genus = Rocio| month = January | year = 2019}}
- Rocio gemmata Contreras-Balderas & Schmitter-Soto, 2007 – from the Yucatan Peninsula, Mexico
- Rocio ocotal Schmitter-Soto, 2007 – from Lake Ocotal, Mexico
- Rocio octofasciata (Regan, 1903) (Jack Dempsey) – from Honduras to southern Mexico
- Rocio spinosissima (Vaillant & Pellegrin, 1902) – Lake Izabal basin, Guatemala
These have historically been placed in the genera Cichlasoma or Heros, but they are quite distinct. R. gemmata and R. ocotal were typically regarded as populations of the closely related R. octofasciata until 2007; a review in 2018 recommended that R. gemmata should be considered a synonym of R. octofasciata,{{cite journal | last=Artigas Azas | first=Juan Miguel | year=2018 | title=Rocio gemmata Contreras-Balderas & Schmitter-Soto, 2007: a subjective junior synonym of R. octofasciata | journal=Cichlid News | volume=27 | pages=22–27 }} whereas a review in 2021 argued that they should be recognized as separate.{{cite journal| last=Schmitter-Soto | first=Juan J. | year=2021 | title=Validity of Rocio gemmata (Teleostei: Cichlidae) | journal=Zootaxa | volume=4991 | issue=1 | pages=195–200 | doi=10.11646/zootaxa.4991.1.13 | pmid=34186725 | s2cid=235685253 }}
