Rocio is a small genus of cichlid freshwater fishes from southern Mexico and northern Central America. ==Species== There are currently four recognized species in this genus: 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, whereas a review in 2021 argued that they should be recognized as separate. ==References==
