Rocio is a small genus of cichlid freshwater fishes from southern Mexico and northern Central America.[1]
Species
There are currently four recognized species in this genus:[1][2]
- 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.[1] 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,[3] whereas a review in 2021 argued that they should be recognized as separate.[4]
Etymology
The genus name is derived from name of J. J. Schmitter-Soto's wife. Meaning dew of the morning in Spanish, this ties in with the colorful spotting that is found in members of this genus.[2]
