From Wikipedia, the free encyclopedia
Metriaclima (type species: Tilapia zebra, Boulenger 1899) is genus of African cichlid containing many of the species traditionally included in the genus Pseudotropheus.[1] All Metriaclima are relatively small, colourful fish found only in Lake Malawi and many of which have some value as aquarium fish.[2]
[edit] Current status
The status of Metriaclima is hotly contested. Many ichthyologists consider the name to be a junior synonym of Maylandia Meyer & Forester 1984.[3][4][5] However, this is far from universally accepted, the argument put forward by advocates of Metriaclima over Maylandia essentially being that Maylandia was inadequately defined in the original description making it impossible to securely attribute species to the genus, rendering the name Maylandia invalid under the ICZN rules for zoological nomenclature.[6]
