Abstract Order Characiformes, one of the world's largest components of the freshwater ichthyofauna with over 2,000 known species, is one of the least studied groups in terms of systematics. Members of this order always have great ecological and economic importance where they occur and are extensively used for human consumption or within the aquarium trade. A recent molecular study published by our research group proposed a new relationship hypothesis for Characiformes, recognized five new families and redefined Characidae. Although that study had provided a major advance in our knowledge on the systematics of Characiformes, there is still need for further phylogenetic studies, especially in relation to many highly species-rich groups within Characidae and several characiform families. A literature review reveals that there is also a necessity of using new and more resolutive markers since many of the interfamilial relationships are still poorly resolved. Thus, we are proposing a phylogenomic reconstruction of Characiformes employing modern techniques of next-generation sequencing using ultraconserved elements (UCEs), which have been shown as a powerful class of markers on the molecular systematics. Thus, the present study with a solid collaborative network of both labs from Brazil and USA, and will be fundamental for a better understanding of which monophyletic groups belong to Characiformes and to test hypotheses of interfamilial, and intergeneric relationships as well as the historical biogeography of Characiformes that is distributed throughout Ethiopic and Neotropical major hydrographic basins.
