A, Malaysia. spec. (AM W 96244), Sarawak, 982. A single spec. (AM W l96245), Sarawak, Bintulu, five.5 m, 982. Description. Holotype (ZMUC POL257) with preshield and shield regions rounded, a lot wider than anterior region which can be elongate, narrow and bent inwards (Fig. 6A, B). Physique papillae couple of, evenly and extensively spaced as filaments more than most of surface on segments ; fewer, shorter papillae on segments PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/11836068 of shield area. Physique as much as eight.5 mm extended, five mm wide, about 28 segments. Prostomium practically spherical, pale yellow. Peristomium oval, raised at position of mouth. Mouth modest, covered by papillae, positioned involving prostomium and anterior border of second segment. Very first three chaetigers with 0 larger and as much as 5 smaller sized flat, bronze, closely connected, falcate hooks per bundle, practically traversing every single segment (Fig. 7B, C); hooks with shaft milky, median or subdistal area dark, distal portion light gold. A single pair of genital papillae protrude ventrally from intersegmental furrow amongst segments seven and eight. Preshield region with 7 segments, with 2 fine capillary chaetae protruding laterally from physique wall on some segments.Kelly Sendall Sergio I. SalazarVallejo ZooKeys 286: 4 (203)Figure 7.

Bars: A .two mm B mm C 0.6 mm D 0.four mm E . mm (Images: J gen Olesen).Ventrocaudal shield ribs barely noticeable, concentric lines not visible; suture poorly defined, apparently extended all through shield (Fig. 7D). Anterior margins angular; anterior depression deep; anterior keels exposed, with median notch. Lateral margins curved, expanded medially, decreased posteriorly. Fan truncate with two lateral notches plus a median, rounded projection, not extended beyond posterior corners, margin denticulated. Marginal chaetal fascicles involve nine lateral ones, chaetae ovally arranged, and 5 posterior fascicles, chaetae in evenly spaced straight rows. Peg chaetae translucent, lighter in colour than other marginal chaetae, as long as, or longer than posterior fascicles chaetae. Peg chaetae emerge from beneath shield on a fleshy cone, with a wide base in cross section. Extra fine, short, capillary chaetae next to peg chaetae, medially to 1st 
fascicle of posterior shield chaetae. Branchiae handful of, stout, tightly coiled (Fig. 7E), protrude from two nearly parallel plates.Revision of Sternaspis Otto, 82 (Polychaeta, Sternaspidae)Etymology. The species name is derived from the Andaman Sea and also the suffix indicates it lives in that area. Sort locality. Andaman Sea, Thailand, 45 m. Remarks. Sternaspis andamanensis sp. n. differs in several functions from any other species. The arrangement and sparseness of papillae around the cuticle, a narrow anterior region, milky introvert hooks, lengthy and translucent peg chaetae, hourglassshaped shield, shield chaetae protruding from a translucent band of cuticle about the shield, and posterior chaetae along the shield in an virtually continuous row, are all SR-3029 web significant variations. The other species obtaining a shield using a denticulate posterior margin is S. africana but besides the variations in physique papillation which can be evident in S. africana and missing in S. andamanensis, the general shape with the shield differs too. In S. andamanensis the anterior margins are projected markedly beyond the anterior depression, plus the fan is medially markedly pro.
