Fig 1.
Neighbour-joining (NJ) tree of Kimura-two-parameter (K2P) distances of the traditional DNA barcode region (about 650 bp region near the 5′ terminus of the cytochrome oxidase subunit I) in seven Palaearctic Gasterophilus species.
Numbers given at branches refer to bootstrap proportions among 1000 bootstrap replicates. Red triangles indicate G. flavipes. Scale bar represents 0.01 nucleotide substitutions per site.
Fig 2.
Neighbour-joining (NJ) tree of Kimura-two-parameter distances of a 663 bp region near the 3′ terminus of the cytochrome c oxidase subunit I (COI) (A = all data, B = only verified identifications) in seven Palaearctic Gasterophilus species.
Numbers given at branches refer to bootstrap proportions among 1000 bootstrap replicates. Red triangles indicate G. flavipes. Asterisks indicate questionable identifications. Scale bar represents 0.01 nucleotide substitutions per site.
