Neighbor-joining tree and result of molecular species delimitation based on COI barcodes. AConiopterygidaeBChrysopidaeCHemerobiidaeDMyrmeleontidae and Ascalaphidae. The terminal nodes in the tree are collapsed for each morphological species, the width of triangles shows the sequence divergence. Only bootstrap supports (1,000 replicates) > 0.95 are labelled.
