The proposed neotype (ICZN 999, Art. 75.3.five), and distinct in the other Mediterranean
The proposed neotype (ICZN 999, Art. 75.three.5), and distinct in the other Mediterranean species, S. thalassemoides Otto, 82, since it includes a rather straight posterior margin. This feature is constant and has been located within the studied supplies; they incorporated specimens from the eastern Italian coast, which could be related towards the original variety locality 
(Adriatic Sea). Even so, the top specimen was selected as neotype and it was collected inside the Aegean Sea, some distance in the original variety locality (ICZN 999, Art. 75.3.six). As stated above, there had been no variations among the supplies studied. The neotype and extra paraneotypes happen to be deposited within the Royal British Columbia Museum (ICZN 999, Art. 95.three.7).Revision of Sternaspis Otto, 82 (Polychaeta, Sternaspidae)As stated above, S. scutata differs from S. thalassemoides by shield functions, particularly relating to their fan improvement; in S. scutata it truly is notched and markedly expanded beyond the level of the posterior corners, whereas in S. thalassemoides it truly is truncate, complete, and not expanded beyond the posterior corners level. Further, S. scutata is exclusive within the genus by a combination PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/12172973 of options of their shields: the anterior margins are truncate, the lateral margins are straight or barely rounded, and the posterior margin and fan are markedly expanded beyond the posterolateral corners. Distribution. Mediterranean Sea to the English Channel, 96 m depth. Deeper water records from the Eastern Mediterranean (BenEliahu and Fiege 995) deserve a careful comparison to define if they may be conspecific together with the shallow water material. Some records from nonMediterranean or Northeastern Atlantic localities could possibly belong to other, almost certainly undescribed species. Following segments with welldefined single rows of clustered, longer filamentous, white papillae; bigger specimens with median segments papillae eroded. Neotype 7.five mm long, 8.7 mm wide; body as much as 20 mm lengthy, eight.five mm wide, about 29 segments. Prostomium hemispherical, opalescent in larger men and women, translucent in smaller people. Peristomium rounded, compact. Mouth oval, covered by papillae (bright white in smaller specimens), extends from prostomium to anterior edge of second CCT244747 web segment.Figure four. Sternaspis spinosa Sluiter, 882, Neotype (NHM 889.six.5.52, No. 36) A Comprehensive, ventral view B Very same, anterior end, exposed, oblique lateral view C Very same, ventrocaudal shield. Bars: A .four mm B .0 mm C 0.8 mm.Revision of Sternaspis Otto, 82 (Polychaeta, Sternaspidae)1st three anterior chaetigers with more than 0 bronze, broadly separated, falcate hooks (paler in smaller specimens), every single with subdistal dark areas (Fig. 4B). Genital papillae protrude ventrally from intersegmental furrow between segments 7 and 8. Preshield region with 7 segments, with quick delicate fascicles of a couple of capillary chaetae on some specimens. Ventrocaudal shield pale brown, normally clean, at times with adhered sediment; ribs not welldefined, concentric lines present; suture extended throughout shield, barely visible. Anterior margins angular; anterior depression shallow; anterior keels exposed (Fig. 4C). Lateral margins rounded, expanded posteriorly. Fan truncate, barely projected beyond posterior corners, margin crenulated. Marginal shield chaetal fascicles incorporate 0 lateral ones, chaetae within a slightly curved arrangement, and five posterior fascicles, chaetae inside a narrow oval arrangement. Peg chaetae narrow, at times so long as posterior shield chaetae. Additional d.
