利用形态特征研究了坦噶尼喀慈鲷族 Cyprichromini 中的两个 Paracyprichromis 和五个 Cyprichromis 物种之间的系统发育关系。先前提出的Paracyprichromis的诊断特征不是共源性，因为非细长的鱼鳔是拟形的，背鳍和臀鳍条的数量以及纵线上和尾柄周围的鳞片数量与Cyprichromis重叠，并且这些计数和椎骨数量都包含在其他坦噶尼喀慈鲷的范围内。 Paracyprichromis 的单系性得到了该属独特的眶下条件的支持。此外，Cyprichromis 的单系性被先前提出的诊断特征之一（细长鱼鳔的存在）再次证实。
The phylogenetic relationships among two Paracyprichromis and five Cyprichromis species, included in the Tanganyikan cichlid tribe Cyprichromini, were investigated using morphological features. The previously proposed diagnostic characters of Paracyprichromis are not synapomorphies, because the nonelongated swim bladder is plesiomorphic, the numbers of dorsal and anal fin rays and scales on longitudinal line and around the caudal peduncle overlap with those of Cyprichromis, and these counts and number of vertebrae are all included within the ranges of other Tanganyikan cichlids. The monophyly of Paracyprichromis is supported by a unique condition of infraorbitals to this genus. Additionally, the monophyly of Cyprichromis was reconfirmed by one of the previously proposed diagnostic characters, the presence of an elongated swim bladder.
