Bleekerij is not considered a valid name.
Bleeker first described the cichlid as polleni 1868, Sauvage described what is thought to be the same species in 1892 as Bleekeri, so polleni takes precedence.
there are species of Paratilapia with large spots (Andapa) and others with small spots. Species are separated by topography on Madagascar, and this seems to separate the species one from another, along with the evolution of larger, smaller of different shades of markings as obvious differences that fit to the different environments..
