Here, we study potential errors that can arise along the data pipeline from sampling, specimen identifcation and molecular processing (digestion, amplifcation and sequencing) to the submission of sequences to these databases by using the DNA sequences of Hydrachnidia (Acari, Parasitengona) as a case study. Our results indicate that molecular information is available for only about 3% of the Hydrachnidia species known to date; yet, within this small percentage, errors are present in almost 5% of the species analyzed (0.5% of the sequences and almost 11% of the genera). This study underscores the scarcity of genetic data available for Hydrachnidia, but also that the proportion of errors in DNA sequences is relatively small. Even so, it highlights the danger associated with using DNA sequences from public databases, particularly for species identifcation, and reinforces the need for greater quality control measures and/ or protocols to avoid an intensifcation of errors in the (post) genomics era. Finally, our study emphasizes that potential errors may also reveal cryptic diversity within a species. eng An evaluation of errors in the mitochondrial COI sequences of Hydrachnidia (Acari, Parasitengona) in public databases journal article URL https://docta.ucm.es/bitstreams/2d9eb346-6a4e-4b5a-b644-4eb2e4937a77/download File MD5 4b67d0b96d1054db11fbe4aff92b4640 723482 application/pdf Peláez_An evaluation_COI sequences.pdf URL https://docta.ucm.es/bitstreams/3e87899c-e4a6-4ccb-b552-9670c3ac2334/download File MD5 735aad44628e10fa89abf868ef0e52fc 39291 text/plain Peláez, M.
