Comments: <i>Ypsolopha dentiferella</i> was designated by Walsingham, 1881:107 as the type for the <i>Ypsolopha dentiferella</i> group which also includes <i>frustella</i> and <i>canariella</i>.
Per Powell & Opler (2009), <i>Ypsolopha dentiferella</i>, <i>frustella</i> and <i>canariella</i> may be conspecific.(1) BOLD mtDNA data seems to support that conjecture. As of 2016, the BIN group, BOLD:AAC0506, contains all three species with all three placed randomly in the TaxonID Tree.
