About the species

Pseudotropheus sp. "Williamsi Makanjila" is an undescribed mbuna allied to the formally described Pseudotropheus williamsi, one of the oldest named mbuna in Lake Malawi, first described by Günther in 1893. This population is recorded from sites spanning Malawian and Mozambican waters in the south-eastern lake, including the Mbenji Islands group, and is distinguished from the nominate species by locality and subtle differences noted by collectors, as it has never been formally compared against P. williamsi in a published revision. The trade name references its affinity to that species and the general Makanjila area of the south-eastern shore. It carries no describing author, FishBase record, or IUCN status of its own.
