摘要

The ornamental fish Amatitlania nigrofasciata, known as the convict or zebra cichlid, is a small Central American tropical freshwater fish that also serves as a model for behavioural studies. Its phylogenetic relationship with other cichlids in the tribe Heroini remains unclear. Here, we sequenced the mitogenome of A. nigrofasciata. The mitogenome spans 16,529 bp and includes the standard complement of 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, and one D-loop region, with the same order and strand distribution as those of other cichlids. Phylogenetic analysis of the 13 PCGs showed that A. nigrofasciata is more closely related to Amphilophus, in a clade including Parachromis, Petenia, and Cryptoheros, with this clade forming a core group of amphilophines within the cichlid tribe Heroini.
