False positive species detected on each library by the intersection approach.

For each library, we indicated the run and library codes, the name of focal species (its order in brackets), the number of congeneric species in the reference database, and a list of the false positive species divided in congeneric and non-congeneric to the focal species. The last three columns contain the number of false positive species detected with the analytical detection limits (ε) of 0, 0.0001 and 0.001. For each non-congeneric species to the focal species, we indicated, in brackets, the RPIR and its order. Order abbreviations are Col: Coleoptera, Dip: Diptera, Hem: Hemiptera, Hym: Hymenoptera, Lep: Lepidoptera.
