To gain a better view into the structure and evolution of the nervous system of the Phylactolaemata, the earliest extant branch and sister taxon to the remaining Bryozoa, this work aims to characterize the nervous system of <jats:italic>Hyalinella punctata<\/jats:italic> with immunocytochemical techniques and confocal laser scanning microscopy. The cerebral ganglion is located between the anus and the pharynx and contains a lumen. Two ganglionic horns and a circum\u2010oral nerve ring emanate from the cerebral ganglion. The pharynx is innervated by a diffuse neural plexus with two prominent neurite bundles. The caecum is innervated by longitudinal neurite bundles and a peripheral plexus. The intestine is characterized by longitudinal and circular neurite bundles, mostly near the anus. Novel putative sensory cells were found in the foregut and intestine. The tentacle sheath is innervated by a diffuse neural plexus, which emanates from several neurite bundles from the cerebral ganglion, but also parts of the pharyngeal plexus. There are six tentacle neurite bundles of intertentacular origin. The retractor muscles are innervated by two thin neurite bundles. Several characters are described herein for the first time in Phylactolaemata: Longitudinal neurite bundles and a peripheral plexus of the caecum, putative sensory structures of the gut, retractor muscle innervation, specific duplicature band neurite bundles. The tentacle innervation differs from previous descriptions of phylactolaemates regarding the origin of the three abfrontal neurite bundles. In general, most organ systems are innervated by a diffuse plexus in phylactolaemates as opposed to gymnolaemates. In contrast to the Gymnolaemata, representatives of Phylactolaemata show a higher number of tentacle nerves. Although the plesiomorphic condition for zooidal features among bryozoans remains unclear, having a diffuse nerve plexus may represent an ancestral feature for freshwater bryozoans.<\/jats:p>","DOI":"10.1002\/jmor.20768","type":"journal-article","created":{"date-parts":[[2017,11,3]],"date-time":"2017-11-03T13:42:25Z","timestamp":1509716545000},"page":"242-258","source":"Crossref","is-referenced-by-count":13,"title":["Neuroanatomy of <i>Hyalinella punctata<\/i>: Common patterns and new characters in phylactolaemate bryozoans"],"prefix":"10.1002","volume":"279","author":[{"given":"Magdalena","family":"Ambros","sequence":"first","affiliation":[{"name":"Department of Integrative Zoology, Althanstra\u00dfe 14 University of Vienna Vienna 1090 Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Wanninger","sequence":"additional","affiliation":[{"name":"Department of Integrative Zoology, Althanstra\u00dfe 14 University of Vienna Vienna 1090 Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0526-6791","authenticated-orcid":false,"given":"Thomas F.","family":"Schwaha","sequence":"additional","affiliation":[{"name":"Department of Integrative Zoology, Althanstra\u00dfe 14 University of Vienna Vienna 1090 Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,11,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.3703.1.14"},{"key":"e_1_2_7_3_1","first-page":"181","article-title":"Studies on recent cyclostomatous Bryozoa","volume":"10","author":"Borg F.","year":"1926","journal-title":"Zoologiska bidrag fr\u00e5n Uppsala"},{"key":"e_1_2_7_4_1","first-page":"1","article-title":"Untersuchungen \u00fcber die Bryozoen des s\u00fc\u00dfen Wassers","volume":"6","author":"Braem F.","year":"1890","journal-title":"Zoologica"},{"key":"e_1_2_7_5_1","first-page":"155","article-title":"\u00c9tude du syst\u00e8me nerveux de quelques Bryozaires Gymnol\u00e9mides","volume":"15","author":"Bronstein G.","year":"1937","journal-title":"Trav Stat Biol Roscoff"},{"key":"e_1_2_7_6_1","first-page":"138","volume-title":"Treatise on Invertebrate Paleontology Part G: Bryozoa","author":"Cheetham A.
