“…As a result, the freshwater fish diversity of the MNCE remains poorly understood (Langeani et al . , ) despite recent studies of Caatinga fishes (Lima et al ., ). The systematic understanding of freshwater fishes from the MNCE is mainly based on brief descriptions, with an abundance of mistaken identifications and confusing taxonomy ( e.g.…”

“…, ). Among these are 24 species described by Fowler (, ), many of which lack diagnostic features, with some probably having inaccurate locality data (Lima et al ., ). The need for an updated list of the MNCE's freshwater fish fauna is especially urgent now because the four main drainages of the ecoregion (Jaguaribe, Piranhas‐Açu, Apodi Mossoró and Paraíba do Norte Basins) will be affected by the ongoing São Francisco interbasin water transfer project (SFR‐IWT), which is now under construction.…”

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 ichthyological collections, 119 species were identified. Among these were 94 putatively valid native and 14 non-native species, five undescribed native species, four new records for the MNCE, 11 potential cases of misidentification and 14 species listed as inquirenda. Additionally, 252 individuals from 49 species were barcoded, revealing three potential taxonomic synonyms. The combined molecular approaches estimated a total of 91 native species, although a finalized species list for the MNCE awaits additional taxonomic revisions and field surveys. This study provides the most up-to-date species checklist for the MNCE and a molecular reference database for identifying MNCE fishes with DNA barcodes. Results highlight the need to integrate traditional taxonomy with molecular approaches to correctly identify species, especially in taxonomically problematic ecoregions such as the MNCE.

Has a non‐native cichlid of the genus Amatitlania (Actinopterygii, Cichlidae) adapted to the headwaters in Brazilian semi‐arid?

Several fish species from Central America and other regions have been introduced into Brazil. In this study, we evaluated the bioecological aspects of a non‐native cichlid of the genus Amatitlania (convict cichlid) and its possible establishment in high‐altitude forest enclaves of semi‐arid Northeastern Brazil. Specimens of Amatitlania nigrofasciata (Günther, 1867) were captured in a local stream displaying abiotic conditions like those of its natural range of distribution. The individuals collected were predominantly adult, insectivorous and displayed normal length–weight relationships, although we observed some phenotypical plasticity (variation in body depth, and a morphologically abnormal dorsal fin in three cases). Our results indicate that A. nigrofasciata has successfully colonized an Atlantic forest enclave in the Brazilian semi‐arid region, making it necessary to adopt measures to prevent the species from spreading to other water bodies in the surroundings.
