Abstract: The mid-north-eastern Caatinga is a semiarid freshwater ecoregion in North-eastern Brazil that is dominated by temporary rivers and is currently classified as one of the least ichthyologically-known ecoregions in the world. The present study aimed to provide an updated checklist of mid-north-eastern Caatinga ecoregion (MNCE) freshwater fish species and evaluate their taxonomic identity using morphology, DNA barcoding and multiple species delimitation approaches. After reviewing published studies and ichthyolog… Show more

“…However, one year later, the São Francisco waters reached Poções reservoirs and M. costae was already established. Moenkhausia costae and M. intermedia (Eigenman 1908) have already been reported in the NCCD ecoregion in the Apodi-Mossoró, Choró and Jaguaribe Rivers basins (Lima et al 2017, Berbel-Filho et al 2018. However, no individual from this genus had ever been registered in the Paraíba do Norte River basin before the São Francisco River diversion (Costa et al 2017.…”

“…Lopes-Lima et al 2019) or uncovering potentially cryptic species (e.g. Pan et al 2019) in many organisms, including freshwater fishes (Patil et al 2018;Berbel-Filho et al 2018;Corral-Lou et al 2019). The results of such methods are dependent on the choice of samples and loci (Ritchie et al 2016;Sukumaran and Knowles 2017) and must be carefully interpreted.…”

“…Due to its particular hydrological regime, MNCE has been historically considered as a scientifically neglected region for freshwater fish surveys (Lévêque et al 2008). However, recent studies have pointed out that the MNCE's ichthyofauna is relatively rich, consisting of around 90 species, approximately 30% endemic (Lima et al 2017;Berbel-Filho et al 2018). Historical negligence in MNCE explains why so far only four freshwater fish species are considered threatened in the ecoregion, besides many human-induced impacts on aquatic habitats, most of them related to the water shortage (Lima et al 2017, ICMBio 2018.…”

“…For the MNCE, only four valid species of seasonal killifish are known, namely Cynolebias microphthalmus Costa & Brasil, 1995, Hypsolebias antenori (Tulipano, 1973), H. martinsi Britzke, D. T. B. Nielsen & C. de Oliveira, 2016 andH. longignatus (Costa, 2008), all endemic to this ecoregion (Tulipano 1973;Costa 1995;2008;Britz-ke et al 2016;Berbel-Filho et al 2018). Among these species, only H. longignatus is currently on the Brazilian red list of threatened fish species, in the vulnerable category, due to the risk of habitat loss to agricultural activities within its restricted geographic distribution (ICMBio 2018).…”
