" The phylogenetic relationships among 13 species of the Tanganyikan cichlid genus Xenotilapia and 12 related genera were investigated based on internal and external morphological features. Xenotilapia is paraphyletic unless Asprotilapia, Enantiopus, and Microdontochromis are treated as junior synonyms. The expanded Xenotilapia is characterized by four infraorbitals, in which the anteriormost bone bears four or five sensory pores and does not overlap the elongated second bone. "
- Enantiopus melanogenys 簡稱 Xenotilapia melanogenys.
- Microdontochromis rotundiventralis 簡稱 Xenotilapia rotundiventralis.
- Microdontochromis tenuidentatus 簡稱 Xenotilapia tenuidentata.
- Xenotilapia bathyphilus 簡稱 Xenotilapia bathyphila.
