Phylogenetic tree of the Menacanthus species based on partial COI sequences, estimated with Bayesian analysis based on a 379 bp alignment of a COI gene fragment. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The numbers above the branches indicate Bayesian posterior probabilities. New sequences are in bold type. — Colors: purple – samples from the Western Palearctic realm; dark purple – samples from the Eastern Palearctic realm; red – samples from the Afrotropical realm; green – samples from the Oriental realm; light blue – samples from the Nearctic realm; dark blue – samples from the Neotropical realm.
