The analysis revealed 15 distinct networks together with seven singletons. Statistical parsimony yielded three networks supporting the species status of <i>Cephalothrix rufifrons</i>, <i>C. major</i> and <i>C. spiralis</i> as they currently have been delineated by morphological characters and geographical location. Many other networks contained haplotypes from nearby geographical locations. Cladistic structure by maximum likelihood analysis overall supported the network analysis, but indicated a false positive result where subnetworks should have been connected into one network/species. This probably is caused by undersampling of the intraspecific haplotype diversity.<h3>Conclusions/Significance</h3>Statistical parsimony network analysis provides a rapid and useful tool for detecting possible undescribed/cryptic species among cephalotrichid nemerteans based on COI gene. It should be combined with phylogenetic analysis to get indications of false positive results, i.e., subnetworks that would have been connected with more extensive haplotype sampling.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Statistical parsimony networks and species assemblages in cephalotrichid nemerteans (Nemertea)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2024-08-19","DateCreate":"2024-08-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1371/journal.pone.0012885"},"refs":null,"anarec":{"AnaID":394232,"PubliDate":2010,"Pagination":"e12885","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":123954,"SerRR":"PLoS One.
