To clarify the genetic relationships among <i>M. japonicus</i> and <i>M. banzai</i> in East Asia and <i>M. japonicus</i> in Australia, a phylogenetic analysis was carried out based on nucleotide sequences of the mitochondrial 12S rRNA to16S rRNA genes (628 base pairs). The resultant tree revealed three major lineages, represented by <i>M. banzai</i>, Japanese and Korean <i>M. japonicus</i>, and Australian <i>M. japonicus</i>. The Australian <i>M. japonicus</i> lineage has diverged considerably from the other two lineages, having an evolutionary distance of 0.208 - 0.246, whereas the sequence divergence between East Asian <i>M. japonicus</i> and <i>M. banzai</i> ranged from 0.088 to 0.105. Although the waving display of Australian <i>M. japonicus</i> is performed in the same manner as in Japanese <i>M. japonicus</i>, other social behaviors, such as fighting and mating, differ somewhat. The genetic and behavioral differences strongly suggest that Australian <i>M. japonicus</i> is a distinct species, separate from East Asian <i>M. japonicus</i>. Among three <i>M. banzai</i> populations investigated, substantial genetic differentiation was observed, with Korean <i>M. banzai</i> being more divergent from two Japanese populations. Differences in waving display and some morphological characters also separate Korean <i>M. banzai</i> from Japanese <i>M. banzai</i>. Although the genetic divergence among these populations was at a level similar to those observed among other intraspecific crustacean populations, the overall differences suggest that Korean and Japanese <i>M. banzai</i> represent a complex of two species or subspecies.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Genetic and behavioral diversity in the <i>Macrophthalmus japonicus</i> species complex (Crustacea: Brachyura: Ocypodidae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:05.984108","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2003-04-24","DateCreate":"2003-04-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000174234500001","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s002270100619"},"refs":null,"anarec":{"AnaID":34237,"PubliDate":2002,"Pagination":"1-8","XtraPublOfAnaID":null,"ISBN":null,"Volume":"140","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
