The orangefin barb, Enteromius eutaenia – a small‐sized smiliogastrin barb characterised by orange/yellow fins, a thickened and serrated last unbranched dorsal‐fin ray, a dark mid‐lateral stripe and a sheath of enlarged scales at the base of dorsal fin – is considered widely distributed across southern Africa. Distinct phenotypic groups suggest unrecognised species‐level diversity, but taxonomic progress has been limited by th...

Aim Lanternfishes (Myctophidae) are one of the most species‐rich families of mid‐water fishes. They inhabit the mesopelagic zone, where physical barriers to dispersal and gene flow are permeable. Thus, modes of speciation that rely exclusively on geographical separation are potentially of less importance than those that rely more prominently on evolution of assortative mating through divergent habitat use and/or sexual signals...

The accuracy and reliability of DNA metabarcoding analyses depend on the breadth and quality of the reference libraries that underpin them. However, there are limited options available to obtain and curate the huge volumes of sequence data that are available on public repositories such as NCBI and BOLD. Here, we provide a pipeline to download, clean and annotate mitochondrial DNA sequence data for a given list of fish species....
