Molecular phylogeny constructed using the maximum likelihood method and COI gene fragment of Metastenasellus specimens from Benin and Cameroon. Partitions at the right side of the figure represent the results of the species delimitation analyses with single-locus methods (ASAP, GMYC, bPTP). Numbers at nodes are ultrafast bootstrap values (BV). Nodes were considered as supported if BVs were higher or equal to 90 (Hoang et al. 2018). For the sake of clarity, BVs are not shown within MOTUs delimited by ASAP and GMYC.
