Iranian cichlids are isolated disjunct populations of African cichlids group, restricted to the Hormuz strait region in Hormuz basin and are a very important group from both zoogeographic and phylogenetic points of view. Thus, the osteological structures, as one of the most reliable structures, of the three nominal species of Iranian cichlid fishes, Iranocichla hormuzensis Coad, 1982, from Mehran River, Iranocichla persa Esmaeili et al., 2016, from Khorgo hot spring and Iranocichla sp., from Kol River was described and compared. Ten specimens of each species were cleared and stained with alcian blue and alizarin red. A digital camera was used for taking pictures and CorelDraw X6 software for preparing drawings. The three species have some differences in the caudal fin skeleton, shape of the urostyle, neural spine of preural 2, hypural spines 2 and 3, anterior part of parhypural and hypurapophysis, the size of neural spines of preural 2 and 3, hypural 3 and 4 and epurals. Although there are some differences among the species, osteology of these species is very conservative and other trait like behavioral and molecular should be used.
