Position of internal degenerative primers within the barcoding region of COI. Aphidius - specific primers: Aph1Fn, Aph1Rn, Aph1Rd, Aph2Fd, Aph2Fn, Aph2Rn, Aph2Rd, Aph3Fd, Aph3Fn and Aph3Rn; Lysiphlebus - specific primers: Lys1Fn, Lys1Rd, Lys2Fn, Lys2Rn, Lys2Rd, Lys3Fd and Lys3Fn; Praon - specific primers: Pr1Fn, Pr1Rn, Pr1Rd, Pr2Fd, Pr2Rn, Pr2Rd, Pr3Fd, Pr3Fn and Pr3Rn. Arrows refer to the direction of the primers, forward or reverse. The exact position of internal primers is designated in comparison to the first nucleotide of the forward LCO1490 primer sequence (5’ GGTCAACAAATCATAAAGATATTGG 3’).
