The Parazoanthidae-sponge associations are widely distributed in tropical and subtropical waters from the intertidal to the deep sea in the Atlantic and Indo-Pacific Oceans. However, the taxonomic identification of both parties is often confused due to variable morphology and wide ecological ranges. In particular, Parazoanthidae species diversity remains poorly understood in the Indo-Pacific. In the present study, the diversity of the sponge-zoanthid association in the Indo-Pacific was investigated with 71 Parazoanthidae specimens collected from 29 different locations in Japan (<i>n</i> = 22), Australia (<i>n</i> = 6) and Florida, USA (<i>n</i> = 1). For all specimens morphological analyses were performed and total DNA was extracted and amplified for four DNA markers (COI-mtDNA, mt 16S-rDNA, ITS-rDNA and ALG11-nuDNA). The combined data demonstrate that the specimens of this study are clearly different from those of all described <i>Parazoanthus</i> species, and lead us to erect <i>Umimayanthus</i> gen. n., within family Parazoanthidae, containing the three newly described species <i>U</i>. <i>chanpuru</i> sp. n., <i>U. miyabi</i> sp. n<i>., U. nakama</i> sp. n. The new genus also includes the previously described species <i>U. parasiticus</i> (Duchassaing and Michelotti, 1860; comb. nov.), previously belonging to the genus <i>Parazoanthus</i>. Neighbor joining, maximum likelihood and Bayesian posterior probability phylogenetic trees clearly demonstrate the monophyly of <i>Umimayanthus</i> gen. n. to the exclusion of all outgroup sequences. The phylogenetic results were also compared to morphological features, and polyp sizes, amount of sand content in tissues, types of connections between polyps, and cnidae data, in particular holotrichs-1, were useful in distinguishing the different species within this new genus. This new genus can be distinguished from all other Zoantharia by a unique and conserved 9 bp insertion and a 14 bp deletion in the mt 16S-rDNA region. Additionally, compared to <i>Parazoanthus</i> sensu stricto (i.e. <i>P. axinellae</i> [Schmidt, 1862]), <i>Umimayanthus</i> spp. are only found associated to sponges, and have a coenenchyme much less developed than <i>Parazoanthus</i> sensu stricto. Each new species can be distinguished from other congeners by a unique DNA sequence, numbers of tentacle, maximum sizes of holotrichs, associated sponge morphology, and colony morphology. The identification of the host sponge species is the next logical step in this research as this may also aid in the distinction of <i>Umimayanthus</i> species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Unexpected diversity and new species in the sponge-Parazoanthidae association in southern Japan","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:02.033076","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"    Parazoanthus; Umimayanthus; Parazoanthid; Sponge; Association","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2017-03-13","DateCreate":"2016-03-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000355640700007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.ympev.2015.04.002"},"refs":null,"anarec":{"AnaID":253604,"PubliDate":2015,"Pagination":"73-90","XtraPublOfAnaID":null,"ISBN":null,"Volume":"89","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45071,"SerRR":"Molecular Phylogenetics and Evolution.
