18 S rDNA-based Bayesian phylogeny of the Trischistomatidae and some other representatives of Enoplida. The new population of Tripylina gorganensis is indicated in bold. Numbers near nodes indicate posterior probabilities. ♀♂ = all species from the marked clade are dioecious; ♀ = males of the species from this clade are unknown or extremely rare.
