An Islands, are all conspecific and pretty much completely match this new species description, while the bigger specimen has a marked notch on the shield’s fan. Distribution. Arabian Sea, in muddy bottoms in shallow water (30 m). Other differences were 
indicated within the important above. Caulleryaspis contains, in addition to the form species, C. gudmundssoni sp. n. from Iceland, C. laevis (Caullery, 944) comb. n. from Indonesia. These species is usually separated due to differences within the shield shape (see key under). Etymology. The genus name would be to honor Dr Maurice Caullery, in recognition of his research on polychaete reproductive biology and taxonomy, and especially because of his monograph around the Siboga Expedition, which took him 40 yr, and contained lots of new species. Caulleryaspis can be a totally free combination of his last name and the second component of Sternaspis (Gr. shield) to strain the affinity together with the stem genus. Gender: feminine. Colour tan, speckeld with compact sediment particles. Abundant, minute cuticular papillae, incorporating fine sediment particles, except within the areas exactly where introvert hooks emerge. Segments seven and PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/23826206 eight with more cuticular papillae near genital papillae. Cuticular papillae not present, even dorsally near ventrocaudal shield, but a few may possibly be present on more posterior segments. Physique 7.5 mm long, 3.5 mm wide, about 28 segments. Prostomium hemispherical, conspicuously extended, white, opaque. Peristomium little, 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.

Genital papillae protrude ventrally from intersegmental furrow involving segments 7 and 8. Preshield regions with 7 segments, smooth, some bearing little groups of fine, short capillary chaetae. Ventrocaudal shield completely 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, decreased posteriorly. Fan truncate, barely reaching posterior corners. Other capabilities not visible. Marginal chaetal fascicles consist of 0 lateral ones, and only 3 quick, smaller posterior fascicles (other ones apparently broken), every single with 3 chaetae concentrated near posterolateral edge of shield. Peg chaetae robust, stout in cross basal section, pale gold, emerge straight from a raised portion of shield, close to posterior margins (Fig. 6A ). Added two couplets or triplets of fine quick capillary chaetae between peg chaetae and first posterior shield chaetae fascicles. Branchiae couple of, pretty slender coiled filaments on two roughly parallel plates; longer, much more slender, straight filamentous papillae closer to anus. Etymology. The species name is derived soon after Dr. Gudmundur Gudmundsson, in the Iceland Organic History Museum in recognition of his longstanding help for our.
