Haplochromis gracilifur Vranken, van Steenberge & Snoeks, 2018


10-Okt.-2018 — Three new cichlid species are described from Lake Edward
Von Juan Miguel Artigas Azas

A new paper authored by Nathan Vranken, M. Van Steenberge, and Jos Snoeks has been published in the journal Hydrobiologia with a study of the cichlids of Lake Edward, concluding with the presence of five species feeding on other cichlids fry (phaedopahgus) in the Lake Edward system, a quite surprising number considering a cichlid fauna that may only reach a total of 60 species (36 described so far), extrapolating, this would mean that 70 phaedopagus species could inhabit Lake Malawi and 20 in Lake Tanganyika; far from this amount are recorded so far. The paper describes three of the species as new: Haplochromis molossus, with a specific name that refers to a “pug-like-head” (Molossus hound is a breed of dog from ancient southern Europe); Haplochromis gracilifur named after its slender body (gracilis = slender in Latin) and paedophagous diet (fur is thief in Latin); and Haplochromis relictidens, named in reference to the decrease in number with size of outer teeth in both jaws (relinquere means relinquish and dens means tooth in Latin); The three new species are established as endemic to the Lake Edward system — including the Kazinga channel for H. relictidens). The other two studied phaedophagus species correspond to Haplochromis taurinus and H. paradoxus.
