Jected as well as the Doravirine lateral notches are deep, whereas in S. africana
Jected and also the lateral notches are deep, whereas in S. africana the anterior margins are usually not so projected beyond the anterior depression, plus the fan is barely projected medially and you can find no lateral notches. Distribution. Identified from two locations: Thailand in the Andaman Sea and Malaysia in the South China Sea, 55 m depth.

Neotype (CMNH ZW20) with body colour creamy white to yellowwhite, sometimes far more grey, with very first six PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24659589 segments lighter, becoming darker when dried out (Fig. 8A). Cuticle largely with brief filamentous papillae, somewhat longer on segments seven and eight. Rows of clustered filamentous papillae typically in two loosely arranged, lateral rows per segment, additional noticeable on posterior segments dorsal to ventrocaudal shield. Physique as much as 22 mm lengthy, 0 mm wide, about 29 segments. Prostomium tiny, hemispherical, slightly opalescent. Peristomium rounded, raised at mouth, with some papillae in between mouth and prostomium. Mouth densely papillate, slightly oval, positioned halfway involving prostomium and anterior edge of segment 2. Initial 3 chaetigers with 0 bronze, slightly falcate, introvert hooks with about an additional 5 smaller hooks ventral to bigger hooks. Hooks broadly separated (extensively apposed), with subdistal dark places. 1 pair of genital papillae protrude ventrally from intersegmental furrow involving segments 7 and eight. Preshield region with 7 segments, with compact fascicles of fine short capillary chaetae laterally in some specimens. Ventrocaudal shield dark orange, frequently 
covered with sediment; ribs and concentric lines visible; suture extended throughout the shield (Figs B, 8B ). Anterior margins rounded; anterior depression shallow; anterior keels not exposed. Lateral margins rounded, expanded posteriorly. Fan slightly projected posteriorly, markedly notched medially.Figure 8.
