“…Other HTS‐based techniques, such as Restriction site‐Associated DNA sequencing (RAD‐seq), genome skimming, or even whole‐genome sequencing, are currently being developed and used for detecting cryptic diversity in various taxa. Nevertheless, as a handy, easy to establish, and widespread identification tool, and due to the presence of huge reference library, DNA barcoding of metazoans will continue to develop in the future, most likely in the direction of multimarker DNA barcoding, as it is currently practiced in fungi and plants (Coissac et al, 2016; DeSalle & Goldstein, 2019; Grant et al, 2021). We therefore highly recommend characterization of test animals via DNA barcoding.…”

The advent of genetic methods has led to the discovery of an increasing number of species that previously could not be distinguished from each other on the basis of morphological characteristics. Even though there has been an exponential growth of publications on cryptic species, such species are rarely considered in ecotoxicology. Thus, the particular question of ecological differentiation and the sensitivity of closely related cryptic species is rarely addressed. Tackling this question, however, is of key importance for evolutionary ecology, conservation biology, and, in particular, regulatory ecotoxicology. At the same time, the use of species with (known or unknown) cryptic diversity might be a reason for the lack of reproducibility of ecotoxicological experiments and implies a false extrapolation of the findings. Our critical review includes a database and literature search through which we investigated how many of the species most frequently used in ecotoxicological assessments show evidence of cryptic diversity. We found a high proportion of reports indicating overlooked species diversity, especially in invertebrates. In terrestrial and aquatic realms, at least 67% and 54% of commonly used species, respectively, were identified as cryptic species complexes. The issue is less prominent in vertebrates, in which we found evidence for cryptic species complexes in 27% of aquatic and 6.7% of terrestrial vertebrates. We further exemplified why different evolutionary histories may significantly determine cryptic species' ecology and sensitivity to pollutants. This in turn may have a major impact on the results of ecotoxicological tests and, consequently, the outcome of environmental risk assessments. Finally, we provide a brief guideline on how to deal practically with cryptic diversity in ecotoxicological studies in general and its implementation in risk assessment procedures in particular.
