“…For example, DNA barcoding has been proposed as a tool for rapid species identification (Hebert et al, 2003(Hebert et al, , 2004, but the term 'species identification' has not had a standard meaning in the barcoding literature (Goldstein & DeSalle, 2011;Collins & Cruickshank, 2013;DeSalle & Goldstein, 2019). Further issues relate to adherence of arbitrary distance thresholds (Wiemers & Fiedler, 2007), incomplete reference databases, misidentified sequences and more (Collins & Cruickshank, 2013;Ransome et al, 2017;Paz & Rinkevich, 2020). In spite of these complications, improvements have been made to optimize identification thresholds and assess their viability for certain groups (Virgilio et al, 2012), and it cannot be denied that molecular data have proven vital to the discovery of cryptic species, which are two or more distinct species previously unrecognized due to apparent or real morphological resemblance (Bickford et al, 2007).…”
