Abstract / Notes
Four new species of Plagiostomidae are described: Plagiostomum lutile sp. nov., Plagiostomum personatum sp. nov., Plagiostomum gibbum sp. nov. and Torgea phukettensis sp. nov., all from the area of Phuket, Thailand. To investigate the monophyly of the taxa Torgeidae, Torgea, and Paramultipeniata, a molecular phylogenetic analysis of the 18S rDNA sequences of Torgea phukettensis and Paramultipeniata lemani, in combination with all published plagiostomid 18S rDNA sequences, is performed. Torgeidae is shown to be an ingroup of the Plagiostomidae, and is therefore synonymized with Plagiostomidae. Paramultipeniata lacks the single character diagnostic of Multipeniata, and both morphology and molecular analysis suggest a placement within Plagiostomum. Paramultipeniata is therefore synonymized with Plagiostomum. Torgea similarly nestles inside Plagiostomum, but as Torgea is based on a strong apomorphy (the possession of a pharynx complex made up by the pharynx and muscular ventral buccal lining) it is provisionally retained, awaiting a complete revision of Plagiostomidae with allied taxa.| Home page -- (Main hierarchy) |
