About the species

Pseudotropheus sp. "Williamsi Maleri" is an undescribed mbuna cichlid from the Maleri Islands — Nakantenga, Namalenje, and Nankoma — a well-known island group in the southern part of Lake Malawi. Its trade name places it close to the formally described species Pseudotropheus williamsi (Günther, 1893), one of the classic barred mbuna of the lake, while marking this particular island population as taxonomically distinct and unnamed. No authority, year of description, FishBase number, or Red List status should ever be attached to it.
