AbstractSexual condition has been employed as a key character within the moss family Thuidiaceae to discriminate the dioicous genera Aequatoriella and Thuidiopsis from the monoicous Pelekium. Here, we implemented phylogenetic analyses of the chloroplast trnL-F region and two unicopy nuclear regions to test the monophyly of Pelekium, and hence, the taxonomic significance of the variation in sexual systems. Aequatoriella was deeply nested within Pelekium, suggesting that the sexual condition is not a fixed character state that can be used to circumscribe genera in the Thuidiaceae and, therefore, that Aequatoriella should be sunk. Incongruence among loci rendered the interpretation of the position of Thuidiopsis challenging, and we suggest maintaining it as a separate genus pending further evidence.
