Ptychochromis mainty, a new cichlid species from southeastern Madagascar has been described by biologists in the journal Biotaxa. The fish was described from four individuals that hailed from the Fort Dauphin area of the island nation. It is different from other congeners in that it is dark brown to black in coloration and has a black mid lateral blotch that extends from the opercle to the caudal peduncle.
The fish is a dark olive in coloration with long pelvic fins and a distinctive anal fin. Its dorsal fins are also fairly long in the back and extend shorter toward the front of the fish. It is named mainty, which means black in Malagsy, for its dark blotch that appears on its side.
