lodotropheus sprengerae Oliver & Loiselle, 1972 (Osteichthyes, Perciformes): proposed replacement of holotype by a neotype

" The purpose of this application is to conserve the specific name of Iodotropheus sprengerae Oliver & Loiselle. 1972 for a small, rock-dwelling fish (family Cichlidae) endemic to Lake Malawi, East Africa. I. sprengerae is the type species of Iodotropheus Oliver & Loiselle, 1972. The description of the taxon was based on aquarium-reared, possibly hybridized, specimens, the original brood stock of which was purported to have been collected from Boadzulu Island in the southeast of the lake, where the species does not occur. The holotype is not within the morphological range of wild specimens. It is proposed that the type material be set aside and a wild-caught specimen from Chinyankwazi Island, where the species is now known to occur, be designated as the neotype. The species is popular as an aquarium fish and is commonly known as the rusty cichlid "
