To date, two species of this genus had been described: <i>I. mirabilis</i> Lévi from the Indo-Pacific and <i>I. notabilis</i> (Duchassaing & Michelotti) from the central Atlantic. A re-examination of material previously assigned to the genera <i>Igernella</i> and <i>Darwinella</i> allowed us to detect the existence of a second species of <i>Igernella</i> in the central Atlantic. <i>Igernella vansoesti</i> sp. nov. is erected to include the specimens from the Cape Verde Islands assigned to <i>I. notabilis</i> by Van Soest (1993), and one specimen from the Gulf of Mexico formerly recorded under the name <i>D. muelleri</i>Schulze by De Laubenfels. The specimen described as <i>D. joyeuxi</i> Tosent by Little (1963) probably belongs to this species as well. The new species is distinguishable from <i>I. notabilis</i> by its massive growth habit -without conspicuous tubes-, a minutely conulose surface, small oscules, and a skeletal network, made of narrow primary and secondary fibers, denser than that of <i>I. notabilis</i>. There is an important amount of foreign material embedded in the mesohyl whereas it is scarce within the fibers or even absent. The absence of debris in the fibers of some species of <i>Igernella</i> suggests a close relationship between this genus and other genera of the family Darwinellidae. This is in agreement with a recent proposal of moving the genus <i>Igernella</i> from the family Dictyodendrillidae to the family Darwinellidae on the basis of their chemical affinities.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The genus <i>Igernella</i> (Demospongiae: Dendroceratida) with description of a new species from the central Atlantic","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1996,"MonPub":null,"DateUpdate":"2021-02-23","DateCreate":"2000-08-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":923,"PubliDate":1996,"Pagination":"153-163","XtraPublOfAnaID":null,"ISBN":null,"Volume":"66","Issue":"Suppl.","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44202,"SerRR":"Bulletin van het Koninklijk Belgisch Instituut voor Natuurwetenschappen.
