Process (Fig. H). Colour white, slightly opalescent, dirty white on posterior segments. Cuticle Methoxatin (disodium salt) covered by minute papillae, especially on segments seven and eight along with the segments near ventrocaudal shield. Body up to 29 mm lengthy, mm wide, 30 segments.Kelly Sendall Sergio I. PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/18686015 SalazarVallejo ZooKeys 286: four (203)Prostomium hemispherical, opalescent, light yellow in colour. Peristomium rounded, raised at position of mouth and without the need of papillae. Mouth oval, covered by minute papillae, extends from edge of second segment halfway towards the border of prostomium. Initially 3 chaetigers with about 05 bronze, extensively separated, slightly falcate introvert hooks, every single with subdistal, narrow dark areas. Genital papillae protrude ventrally from intersegmental groove among segments 7 and eight (Fig. I). Preshield area with 7 segments, in some cases with row of little, short fascicles of fine capillary chaetae, barely protruding from physique wall laterally. Ventrocaudal shield surface just about flat. Shield surface faintly ribbed with 1 bigger oblique rib; suture indistinct, barely defined anteriorly, poorly defined posteriorly (Fig. I); bigger syntype with faint concentric lines, smaller person with a lot more distinct concentric lines. Anterior margins rounded; anterior depression deep; anterior keels not exposed. Lateral margins straight, barely expanded posteriorly. Fan truncate, margin crenulated, with shallow median notch. Marginal chaetal fascicles incorporate ten lateral ones, and six posterior fascicles; all chaetae broken on each syntypes, except for 1st two lateral fascicles. Peg chaetae present as stubs. Added chaetae damaged. Branchiae lost; branchial plates visible, oriented close to parallel with respect to every other. Remarks. Selenka (885) indicated a shallow furrow running along the middle of the ventral surface, dividing every half into a larger anterior triangle plus a smaller sized posterior triangle. Despite the fact that he didn’t indicate this specifically, he 
was most likely referring to the anterolateral and posterior portions of your shield. He also counted 40 tufts of chaetae along the margins on the shield. When the secondary groups of chaetae, which include the delicate fascicles at the posterolateral edges are integrated, there are actually nevertheless only 34. Since a single syntype is very big, and chaetal fascicles may well be irregularly broken, he could possibly have inadvertently counted a few with the fascicles more than when. There are five species obtaining shields with straight posterior margins: S. princeps, S. rietschi, S. spinosa, S. thalassemoides and S. thorsoni sp. n. Sternaspis princeps is most comparable to S. thalassemoides mainly because each have deep anterior depressions and rounded anterior margins. Having said that, they differ due to the fact in S. princeps only the larger, radial rib is additional or significantly less visible, but concentric lines are not, whereas in S. thalassemoides the shield has radial ribs and concentric lines. An more difference is the fact that in S. princeps the shield anterior keels are exposed whereas they may be covered in S. thalassemoides. Distribution. Only identified in the type locality, off North Island, New Zealand, about 274 m depth.
