TY - JOUR T1 - Phylogeny of the Prolecithophora (Platyhelminthes) Inferred from 18S rDNA Sequences JF - Cladistics Y1 - 1999 DO - 10.1111/j.1096-0031.1999.tb00252.x A1 - Noren, Michael A1 - Jondelius, Ulf SP - 103–112 KW - Boot-strap KW - Jack-knife KW - Neodermata KW - parsimony KW - SSU AB - Complete nuclear 18S rDNA sequences from 14 species of the Prolecithophora were obtained and used, in combination with literature data, to generate the first parsimony-based hypothesis of the phylogeny of the order Prolecithophora (Platyhelminthes). Bootstrap, parsimony jack-knife, and Bremer support values were computed and compared. The monophyly of the Prolecithophora sensu stricto and the family Plagiostomidae is strongly supported. The taxa Separata, Combinata, and Plagiostomum are shown to be nonmonophyletic. Cylindrostomidae and Ulianinidae are transferred to Pseudostomidae. The Urastomidae is not part of the Prolecithophora.

The results are largely compatible with earlier molecular studies when supported clades are considered, and adjusting for the denser taxonomic sampling of this study. The position of the Proseriata is not compatible with the taxon Seriata, which is rejected. The Rhabdocoela excluding the Fecampiida and the Neodermata is monophyletic. The phylogenetic position of the Neodermata cannot be determined, but its placement is not compatible with the proposed taxa Revertospermata and Mediofusata Kornakova & Joffe, 1999, which are rejected. The Urastomidae and the Genostomatidae in all analyses group with the Fecampiida, and it is our recommendation that these taxa be included in the Fecampiida. The amended Fecampiida always group separately from the Prolecithophora sensu stricto, the Rhabdocoela, and the Neodermata. Our analyses reveal the existence of a strongly supported clade consisting of Prolecithophora + Tricladida + the amended Fecampiida, and we propose the name Adiaphanida for this clade. Tentatively the sister group of the Prolecithophora is a clade consisting of the Tricladida + amended Fecampiida.
