Tree topology obtained by maximum likelihood in IQ-TREE v. 2.0 using combined genes of 18 mysmenid species from NCBI plus eight Microdipoena species (red font). Numbers at nodes indicate bootstrap values. Note fifteen species representing the genus Microdipoena are clustered into a monophyly but with low support; the high support of eight species (red font) in the genus Microdipoena (pale box). Mysmena (including four undescribed species in blue box), Trogloneta (pink box) and Yamaneta (yellow box) are also monophyletic and with high support respectively.
