Two New Genera of the Pelagic Family Yndolaciidae (Polychaeta) from the Arctic Ocean with an Addition to the Description of Yndolacia Lopadorrhynchoides Støp-Bowitz Published in collaboration with the University of Bergen and the Institute of Marine Research, Norway Two new genera of the pelagic family Yndolaciidae (Polychaeta) from the Arctic Ocean with an addition to the description of Yndolacia lopadorrhynchoides Støp-Bowitz Galina N. Buzhinskaja SARSIA Buzhinskaja GN. 2004. Two new genera of the pelagic family Yndolaciidae (Polychaeta) from the Arctic Ocean with an addition to the description of Yndolacia lopadorrhynchoides Støp-Bowitz. Sarsia 89:338–345. Until recently, the pelagic family Yndolaciidae was considered to include a single genus and species Yndolacia lopadorrhynchoides Støp-Bowitz, 1987 from the Gulf of Guinea. Yndolaciella polarsterni gen. et sp. nov. and Paryndolacia tomopteroides gen. et sp. nov. are described from the deep sea of the Arctic Ocean. Additions and refining of the diagnoses of the genus Yndolacia and the family are given. The absence of cephalic tentacles, a weakly developed brain, simple biramous parapodia with equal rami, similar cirri without cirrophores, a superficial position of the nervous system, the presence of two nerve cords and the lack of ganglionic swellings are assumed to constitute ancestral characters of the family. Some resemblance of the family to Tomopteridae is noted. It is supposed that fossil polychaete Eotomopteris aldridgei Briggs & Clarkson, 1987 belongs to Yndolaciidae. Galina N.

Memoirs of Museum Victoria 71: 247–269. Annelida, traditionally divided into Polychaeta and Clitellata, is an evolutionary ancient and ecologically important group today usually considered to be monophyletic. However, there is a long debate regarding the in-group relationships as well as the direction of evolutionary changes within the group. This debate is correlated to the extraordinary evolutionary diversity of this group. Although annelids may generally be characterised as organisms with multiple repetitions of identically organised segments and usually bearing certain other characters such as a collagenous cuticle, chitinous chaetae or nuchal organs, none of these are present in every subgroup. This is even true for the annelid key character, segmentation. The first morphology-based cladistic analyses of polychaetes showed Polychaeta and Clitellata as sister groups.

Common occurrence of the species is restricted to sediments laden with mats of filamentous sulphide-oxidizing bacteria. The body comprises a small prostomium and nine segments; the last is fused with the pygidium. The head has two large, ventrolateral palps, antennae are absent. The first segment (buccal segment) has neither parapodia nor chaetae. Segments II to IX possess parapodial cirri of similar size. Thin capillary chaetae are restricted to posterior segments, only one-two ventral chaetae exist per parapodium. Two pear-shaped anal cirri are present. Distinct characters that separate the new taxon from all hitherto known nerillids are: (1) most specimens completely lack chaetae, while others have only very few chaetae, (2) in the pharyngeal organ, the bulbous muscle is covered anteriorly by an eversible epithelial part. This ventrally located tongue contains intracellular buccal pieces. A brief summary of the 16 known genera of Nerillidae is presented in a tabular form.

The traditionally recognized classes were Polychaeta, Oligochaeta and Hirudinea. The latter two are now viewed as the taxon Clitellata, since recognizing Hirudinea with class rank renders Oligochaeta paraphyletic. Polychaeta appears to contain Clitellata, and so may be synonymous with Annelida. Current consensus would place previously rec- ognized phyla such as Echiura, Pogonophora, Sipuncula and Vestimentifera as annelids, though relationships among these and the various other annelid lineages are still unresolved. Key words: Polychaeta, Oligochaeta, Clitellata, Echiura, Pogonophora, Vestimentifera, Sipuncula, phylogeny, review Introduction Annelida is a group commonly referred to as segmented worms, found worldwide in terrestrial, freshwater and marine habitats. The first annelids were formally named by Linnaeus, including well-known forms such as the earthworm Lumbricus terrestris Linnaeus, 1758, the medicinal leech Hirudo medicinalis Linnaeus, 1758, and the sea-mouse Aphrodite aculeata Linnaeus, 1758.

  • A Check-List of Polychaete Species from the Black
    J. Black Sea/Mediterranean Environment Vol. 18, No.1: 10-48 (2012) REVIEW ARTICLE A check-list of polychaete species (Annelida: Polychaeta) from the Black Sea Güley Kurt Şahin1*, Melih Ertan Çınar2 1Department of Biology, Faculty of Arts and Sciences, Sinop University, 57000, Sinop, TURKEY 2Department of Hydrobiology, Faculty of Fisheries, Ege University, 35100, Bornova- Izmir, TURKEY *Corresponding author: [email protected] Abstract Polychaetes from the Black Sea were reviewed based on the available literature. Lists of the valid species, re-assigned species and dubious species (nomen dubium or indeterminable species) reported from the region are provided. The checklist comprises 238 valid species belonging to 45 families. Twenty three species belonging to 8 families were considered as nomen dubium or indeterminable. Fifty-one species reported from the Black Sea between 1868 and 2011 have been synonymised with other species. Among the Black Sea countries, the coast of Bulgaria is represented by the highest number of polychaete species (192 species), followed by the coasts of Ukrania (161 species) and Romania (115 species). The highest number of species (119 species) were found on sandy substratum, the lowest number of species (7 species) on sponges. Nine alien polychaete species (Hesionides arenaria, Streptosyllis varians, Glycera capitata, Nephtys ciliata, Polydora cornuta, Prionospio pulchra, Streblospio gynobranchiata, Capitellethus dispar and Ficopomatus enigmaticus) were reported from the Black Sea up to now. The most speciose families in the area were Syllidae (32 species), Spionidae (31 species), Phyllodocidae (16 species) and Nereididae (15 species). By presenting a complete overview of the species reported from the area, this work summarises our current knowledge about the diversity of the Black Sea polychaetes and provides a database for future studies.

  • Morphological Investigations of Posttraumatic Regeneration in Timarete Cf
    Weidhase et al. Zoological Letters (2015) 1:20 DOI 10.1186/s40851-015-0023-2 RESEARCH ARTICLE Open Access Morphological investigations of posttraumatic regeneration in Timarete cf. punctata (Annelida: Cirratulidae) Michael Weidhase1*, Conrad Helm2 and Christoph Bleidorn1 Abstract Introduction: Annelids exhibit great regenerative abilities, which are mainly used after injury or during reproduction. These lophotrochozoans thus represent excellent models for regeneration research. However, detailed morphological studies concerning annelid musculature and nervous system redevelopment are limited to few taxa, and do not allow for broader comparisons and general conclusions regarding common patterns amongst annelids. Results: Using immunohistochemical staining combined with confocal laser scanning microscopy (cLSM), we investigated the redevelopment of body wall musculature and nervous system during anterior and posterior posttraumatic regeneration in Timarete cf. punctata. Both regeneration processes start with wound healing, blastema formation, and blastema patterning. In posterior regeneration, this leads to the development of a new pygidium and a segment addition zone (SAZ) anterior to this structure. New segments are subsequently added in a sequential fashion. Anterior regeneration in contrast shows the formation of a new prostomium and peristomium first, followed by the simultaneous redevelopment of three segments, and an additional three segments in sequential order. Anterior muscular regeneration shows an outgrowth of longitudinal musculature from the residual body wall musculature, while circular musculature develops independently within the blastema. During posterior regeneration, new musculature becomes visible when the new segments reached a certain age. Neuronal regeneration begins with neurite outgrowth from the old ventral nerve cord in both cases, which are later forming loop structures. In anterior regeneration, the brain redevelops at the anteriormost position of the loops.

CHRISTOFFERSEN Turk J Zool 2012; 36(1): 95-119 © TÜBİTAK Research Article doi:10.3906/zoo-1002-27 Phylogeny of basal descendants of cocoon-forming annelids (Clitellata) Martin Lindsey CHRISTOFFERSEN* Federal University of Paraiba, Department of Systematics and Ecology, 58.059-900, João Pessoa, Paraíba - BRAZIL Received: 09.02.2010 Abstract: Molecular analyses have been unsuccessful in placing the clitellates among annelids. Available morphological characters are ordered into congruent transformation series according to Hennigian principles. Orbiniidae is chosen as the outgroup. I propose the following phylogeny [number of apomorphies within brackets]: (Clitellata sensu lato [6] (Questidae [6] + Apodadrilida, new [2] (Parergodrilidae [3] (Stygocapitella [3] + Parergodrilus [4]) + Oligochaeta [7] (Aphanoneura [2] (Aeolosomatidae [2] + Potamodrilidae [3]) + Dorsopharyngea, new [7] (Hrabeiellidae, new [6] + Euclitellata [5])))). Worms with ring-like clitella surrounding the body almost completely are herein renamed Euclitellata. Clitellata is expanded to include all annelids that, in addition to producing cocoons, have sperm receptacles and a restricted number of gonads. Oligochaeta is established as a valid clade for the hermaphroditic annelids bearing few or no chaetae. Questidae, Parergodrilidae, and Hrabeiella belong to Clitellata. Terrestrial “polychaetes”, such as Parergodrilus and Hrabeiella, are actually clitellates. Hrabeiella is the sister group of Euclitellata, despite a secondary loss of spermathecae and clitellum. Aphanoneura
