An Islands, are all conspecific and practically entirely match this new
An Islands, are all conspecific and virtually entirely fit this new species description, though the bigger specimen includes a marked notch on the shield’s fan. Distribution. Arabian Sea, in muddy bottoms in shallow water (30 m). Other differences have been indicated within the crucial above. Caulleryaspis consists of, apart from the sort species, C. gudmundssoni sp. n. from Iceland, C. laevis (Caullery, 944) comb. n. from Indonesia. These species can be separated as a result of variations within the shield shape (see essential beneath). Etymology. The genus name is always to honor Dr Maurice Caullery, in recognition of his research on polychaete reproductive biology and taxonomy, and in particular due to his monograph around the Siboga Expedition, which took him 40 yr, and contained several new species. Caulleryaspis is actually a no cost combination of his last name plus the second part of Sternaspis (Gr. shield) to pressure the affinity with the stem genus. Gender: PI3Kα inhibitor 1 feminine. Colour tan, speckeld with modest sediment particles. Abundant, minute cuticular papillae, incorporating fine sediment particles, except inside the places exactly where introvert hooks emerge. Segments seven and PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/23826206 eight with a lot more cuticular papillae close to genital papillae. Cuticular papillae not present, even dorsally close to ventrocaudal shield, but a few may perhaps be present on more posterior segments. Body 7.5 mm long, three.five mm wide, about 28 segments. Prostomium hemispherical, conspicuously extended, white, opaque. Peristomium small, oval, bearing some papillae closer to mouth. Mouth oval, small, totally covered by papillae, extends from prostomium to anterior border of second segment.Figure six.

Bars: A .four mm, B 0.eight mm C 0.9 mm (Pictures: Gudmundur Vidir Helgason).Revision of Sternaspis Otto, 82 (Polychaeta, Sternaspidae)Very first three chaetigers with 05 falcate, flat introvert hooks per bundle, closely linked, every single with subdistal dark regions. Genital papillae protrude ventrally from intersegmental furrow involving segments 7 and eight. Preshield regions with 7 segments, smooth, some bearing modest groups of fine, brief capillary chaetae. Ventrocaudal shield fully covered by a thick coating of adhered particles, 
unusually flexible; suture not visible (Fig. 6A ). Anterior margins apparently rounded (shape blocked by sediment cover); anterior depression deep; anterior keels not exposed. Ribs, concentric lines or fan not visible. Lateral margins rounded, expanded medially, lowered posteriorly. Fan truncate, barely reaching posterior corners. Other functions not visible. Marginal chaetal fascicles include things like 0 lateral ones, and only 3 quick, smaller posterior fascicles (other ones apparently broken), each with three chaetae concentrated near posterolateral edge of shield. Peg chaetae robust, stout in cross basal section, pale gold, emerge directly from a raised portion of shield, close to posterior margins (Fig. 6A ). More two couplets or triplets of fine quick capillary chaetae between peg chaetae and initially posterior shield chaetae fascicles. Branchiae handful of, very slender coiled filaments on two roughly parallel plates; longer, much more slender, straight filamentous papillae closer to anus. Etymology. The species name is derived just after Dr. Gudmundur Gudmundsson, in the Iceland All-natural History Museum in recognition of his longstanding assistance for our.
