An updated phylogeny of Iphitime (Annelida: Dorvilleidae) revealing multiple host switching, with description of I. nubila sp. nov.

This dataset contains the digitized treatments in Plazi based on the original journal article Hookabe, Natsumi, Yamamori, Luna, Ogawa, Akito, Jimi, Naoto, Kohtsuka, Hisanori, Rouse, Greg W. (2025): An updated phylogeny of Iphitime (Annelida: Dorvilleidae) revealing multiple host switching, with description of I. nubila sp. nov. Zoological Journal of the Linnean Society 204 (4): 1-16, DOI: 10.1093/zoolinnean/zlaf101, URL: doi.org/10.1093/zoolinnean/zlaf101 ABSTRACT This study provides an updated molecular phylogeny of Iphitime Marenzeller, 1902 (Annelida: Dorvilleidae), a group of symbiotic dorvilleid polychaetes, including a topotypic specimen of the type species, Iphitime doederleini Marenzeller, 1902.

Also, a new species, Iphitime nubila sp. nov., was found associated with hermit crab hosts during a faunal survey off Shirahama, Wakayama, Japan, and is described here. Specimens of Iphitime were also found from southern California that were from the gill chambers of two different hosts of brachyuran crabs and are referrable to Iphitime loxorhynchi Hartman, 1952. The study includes morphological descriptions, ecological observations, molecular phylogenetic analyses,and ancestral state reconstruction highlighting at least two independent host switching in Iphitime.
