Three of the parasites were identified as members of the mesoparasitic copepod genus <i>Herpyllobius</i> Steenstrup and Lütken, and one of <i>Gottoniella</i> López-González, Bresciani and Conradi, (Herpyllobiidae). <i>Herpyllobius chambardi</i> <strong>sp. n.</strong>, found on <i>L. brunnea</i>, is distinguished from its congeneric species by having a longitudinal constriction dividing its globose ectosoma into two symmetrical hemispheres. The second species, <i>H. hourdezi</i> <strong>sp. n.</strong>, on <i>H. samadiae</i>, shows a depressed intergenital margin, lacks sclerotised dots, and exhibits a large endosoma with several thick lobes. <i>Herpyllobius pabloi</i> <strong>sp. n.</strong>, found on <i>E. corbariae</i>, closely resembles its congeneric species <i>H. polynoes</i>, but differs in the endosomal structure and details of the ectosoma. <i>Herpyllobius</i> species are known to infect at least 14 polynoid genera, to which we can now add <i>Lepidasthenia</i> Malmgren, thus expanding its host range among polynoids. These three Papuan species are additional new records of this chiefly cold-temperate copepod genus to be reported from subtropical latitudes. The discovery of <i>Herpyllobius</i> parasitising a species of <i>Harmothoe</i> confirms its preference for infecting this polynoid genus. The new <i>Gottoniella</i>, also on <i>Harmothoe</i> sp. is the third known species of the genus; it has heavily sclerotised genital swellings, slit-like genital openings, a distinctive fin-like lateral ectosomal process, a short, sclerotised ring, and a pipe-like stalk connecting the endosoma. Both <i>H. chambardi</i> and <i>H. hourdezi</i> are among the deep-living members of <i>Herpyllobius</i> in the Southern Hemisphere, the latter representing the deepest record of the genus (780 m) worldwide.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Expanding territories: New host records and four new species of herpyllobiid parasitic copepods (Copepoda: Herpyllobiidae) from Papua New Guinea deep-water polynoid polychaetes (Annelida: Polynoidae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-16 01:34:06.629448","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-08-01","DateCreate":"2025-08-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1080/00222933.2025.2474196"},"refs":null,"anarec":{"AnaID":410347,"PubliDate":2025,"Pagination":"1017-1047","XtraPublOfAnaID":null,"ISBN":null,"Volume":"59","Issue":"13-16","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43088,"SerRR":"Journal of Natural History.
