Cambridge University Press, Cambridge. 212 pp. DIAGNOSTIC CHARACTERS: Large tubulanid worm with cream ground color marked by broad brown banding anteriorly and narrow dark brown rings posteriorly. Dorsum of head distinguished by a longitudinal, middorsal brown band that extends to the end of the body. At the level of the mouth, the band encircles the body and extends anteriorly along the ventrum of the head, leaving the margin of the head cream. The posterior edge of this band is marked by a distinct white ring just posterior to the mouth, and is followed by a brown region which extends through the esophageal region interrupted occasionally by one or two thin white rings. A single, thin, middorsal brown stripe along with numerous transverse brown rings continue from this point through to posterior end of the body. Lateral and ventral longitudinal stripes absent, though the lateral nerve cord appears as a white ventrolateral stripe. Mouth is large white/cream with crenulate border. Lateral sense organ not observed. Tubulanus sp SD1 CSDMWWD 2000 Nemertea: Anopla: Palaeonemertea: Tubulanidae RELATED SPECIES AND CHARACTER DIFFERENCES: This species is distinguished from other Pacific coast species of Tubulanus by the absence of any lateral or ventral longitudinal stripes. It has a strong resemblance to T. frenatus, particularly in the markings of the head, but differs in the absence of ventral-lateral stripes. DEPTH RANGE: 3.3 -10 m DISTRIBUTION: San Diego Bay, San Diego, CA. NOTES: Eight specimens were collected from San Diego Bay during the Bight 98 regional sampling .

Detailed Reconstruction of the Nervous and Muscular System Of
Kerbl et al. BMC Evolutionary Biology (2015) 15:277 DOI 10.1186/s12862-015-0531-x RESEARCH ARTICLE Open Access Detailed reconstruction of the nervous and muscular system of Lobatocerebridae with an evaluation of its annelid affinity Alexandra Kerbl1, Nicolas Bekkouche1, Wolfgang Sterrer2 and Katrine Worsaae1* Abstract Background: The microscopic worm group Lobatocerebridae has been regarded a ‘problematicum’, with the systematic relationship being highly debated until a recent phylogenomic study placed them within annelids (Curr Biol 25: 2000-2006, 2015). To date, a morphological comparison with other spiralian taxa lacks detailed information on the nervous and muscular system, which is here presented for Lobatocerebrum riegeri n. sp. based on immunohistochemistry and confocal laser scanning microscopy, supported by TEM and live observations. Results: The musculature is organized as a grid of longitudinal muscles and transverse muscular ring complexes in the trunk. The rostrum is supplied by longitudinal muscles and only a few transverse muscles. The intraepidermal central nervous system consists of a big, multi-lobed brain, nine major nerve bundles extending anteriorly into the rostrum and two lateral and one median cord extending posteriorly to the anus, connected by five commissures. The glandular epidermis has at least three types of mucus secreting glands and one type of adhesive unicellular glands. Conclusions: No exclusive “annelid characters” could be found in the neuromuscular system of Lobatocerebridae, except for perhaps the mid-ventral nerve. However, none of the observed structures disputes its position within this group. The neuromuscular and glandular system of L. riegeri n. sp. shows similarities to those of meiofaunal annelids such as Dinophilidae and Protodrilidae, yet likewise to Gnathostomulida and catenulid Platyhelminthes, all living in the restrictive interstitial environment among sand grains.

Zattara, [email protected] Abstract Animals vary widely in their ability to regenerate, suggesting that regenerative abilities have a rich evolutionary history. However, our understanding of this history remains limited because regeneration ability has only been evaluated in a tiny fraction of species. Available comparative regeneration studies have identified losses of regenerative ability, yet clear documentation of gains is lacking. We surveyed regenerative ability in 34 species spanning the phylum Nemertea, assessing the ability to regenerate heads and tails either through our own experiments or from literature reports. Our sampling included representatives of the 10 most diverse families and all three orders comprising this phylum.

Each oocyte can attach to the germinal epithelium by a vegetally situated stalk and resides in the ovarian lumen Accepted for publication: without being surrounded by follicle cells. In the ovary, oocytes arrest at 26 September 2000 prophase I of meiosis and contain a hypertrophied nucleus ('germinal vesicle') that often possesses multiple nucleoli. Intraovarian growth apparently involves an autosynthetic mode of yolk formation in most nemerteans and generates oocytes that measure ~60 Jim to 1 mm. When fully developed, oocytes can be discharged through a short gonoduct and are either spawned freely or deposited within egg cases. In most species, oocytes released from the ovary possess extracellular coats and resume maturation by undergoing germinal vesicle breakdown (GVBD).

Resolving a 200-Year-Old Taxonomic Conundrum: Neotype Designation for Cephalothrix Linearis (Nemertea: Palaeonemertea) Based on a Topotype from Bergen, Norway
Fauna norvegica 2019 Vol. 39: 39–76. Resolving a 200-year-old taxonomic conundrum: neotype designation for Cephalothrix linearis (Nemertea: Palaeonemertea) based on a topotype from Bergen, Norway Hiroshi Kajihara1 Kajihara H. 2019. Resolving a 200-year-old taxonomic conundrum: neotype designation for Cephalothrix linearis (Nemertea: Palaeonemertea) based on a topotype from Bergen, Norway. Fauna norvegica 39: 39–76. The taxonomic identity of the palaeonemertean Cephalothrix linearis (Rathke, 1799) has been obscure for nearly two centuries, because its original description applies to almost any congeners, including Cephalothrix filiformis (Johnston 1828) and Cephalothrix rufifrons (Johnston, 1837), which occur commonly in the North Sea and adjacent waters. In this paper, I redescribe C. linearis based on two topotypes from Bergen, one herein designated as the neotype for C. linearis, because Rathke’s original material is not extant; I invoke Article 70.3.2 of the International Code of Zoological Nomenclature to fix Planaria linearis Rathke, 1799 as the type species of Cephalothrix Örsted, 1843 for the sake of stability. From the neotype, I determined sequences of the 28S rRNA, 16S rRNA, and cytochrome c oxidase subunit I (COI) genes. Using the COI sequence, I inferred the phylogenetic position of C. linearis along with 316 cephalotrichid sequences currently available in public databases. A tree-based species delimitation analysis detected 43 entities among them, with 34 in Cephalothrix and nine in either Balionemertes or Cephalotrichella.

Vlasenko and Timur Yu. Magarlamov * A.V. Zhirmunsky National Scientific Center of Marine Biology, Far Eastern Branch, Russian Academy of Sciences, 690041 Vladivostok, Russia; [email protected] * Correspondence: [email protected]; Tel.: +7-914-661-7949 Received: 15 November 2020; Accepted: 25 November 2020; Published: 26 November 2020 Abstract: Some nemertean species from the genus Cephalothrix accumulate tetrodotoxin (TTX) in extremely high concentrations. The current study is the first to provide high-performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) data on tetrodotoxin and its analogues (TTXs) profile and concentration in different regions and organs of Cephalothrix cf. simula, and its secretions produced in response to stimulation. Different specimens of C. cf. simula possessed 7–11 analogues, including nine previously found in this species and two new for nemerteans—4,9-anhydro-8-epi-5,6,11-trideoxyTTX and 1-hydroxy-8-epi-5,6,11-trideoxyTTX. The study of the toxins’ distribution in different regions and organs of nemerteans revealed the same qualitative composition of TTXs throughout the body but differences in the total concentration of the toxins. The total concentration of TTXs was highest in the anterior region of the body and decreased towards the posterior; the ratio of the analogues also differed between regions. The data obtained suggest a pathway of TTXs uptake in C. cf. simula and the role of toxins in the life activity of nemerteans.
