97C773AEB3DDB14F7AD63775D211D486.taxon	etymology	Etymology. The specific name, a noun, is a combination of ascidia (sea squirt) and - cola (dweller), referring to the fact that the species was frequently found among botryllid ascidian colonies.	en	Yoshihara, Taiki, Hiruta, Shimpei F., Katoh, Toru, Kajihara, Hiroshi (2012): Three species of Amphicorina (Annelida, Sabellida, Sabellidae) from Japan, with descriptions of two new species.

Three pairs of radioles, with lateral flanges; proximal 1 / 2 of radioles connected by palmate membrane. Each radiole with two longitudinal internal cellular supporting axes; each pinnule with one internal cellular supporting axis. Ventral-most radiole with two appendages on each side (Fig. 4 A); these appendages (arranged dorsally and ventrally) being almost 1 / 2 radiole length, and only dorsal one having one internal cellular supporting axis. Distal end of ventral lobe on anterior peristomial ring bifurcate, extending slightly beyond collar margin (Figs 3 C, 4 A). Posterior peristomial ring collar crenulate (Figs 3 A, 3 B, 3 C, 4 A, 4 B), with dorsal gap (Fig. 4 B). Ciliated patch absent on posterior peristomail ring (Figs 3 C, 4 A). Glandular ridge on second chaetiger present. Superior thoracic notochaetae elongate, narrowly hooded, 4 - 5 per fascicle (Fig. 3 D). Inferior thoracic notochaetae bayonet type, four per fascicle; no elongate, narrowly hooded chaetae (Fig. 3 D). Thoracic acicular uncini 4 - 5 per torus; each uncinus having four rows of teeth above main fang (Figs 3 E, 4 C). Abdominal uncini quadrangular, with eight rows of teeth above large basal tooth (Figs 3 F, 4 D), 2 - 9 uncini per fascicle; number of uncini decreasing posteriorly, with eight uncini on first and second abdominal chaetigers, nine on third. Abdominal neurochaetae 2 - 4 per fascicle, needle-like capillaries in form (Fig. 3 G). Pygidium rounded. Peristomial and pygidial eyes and statocysts not visible in preserved specimens. Oocytes found in fourth and fifth thoracic chaetigers.	en	Yoshihara, Taiki, Hiruta, Shimpei F., Katoh, Toru, Kajihara, Hiroshi (2012): Three species of Amphicorina (Annelida, Sabellida, Sabellidae) from Japan, with descriptions of two new species.

04B707064DE03CA780E231A8E50D9CE4.taxon	etymology	Etymology. The specific epithet is an adjective derived from Ezo, the old place name for Hokkaido, in combination with the Latin suffix - ensis.	en	Yoshihara, Taiki, Hiruta, Shimpei F., Katoh, Toru, Kajihara, Hiroshi (2012): Three species of Amphicorina (Annelida, Sabellida, Sabellidae) from Japan, with descriptions of two new species.

89564131951997F4BB5389F276D7E942.taxon	description	Description. Complete specimens have eight thoracic and five abdominal chaetigers (Fig. 5 A). Total length 1.2 - 3.2 mm (mean, 2.3 mm; n = 9), crown length 0.2 - 0.6 mm (mean, 0.4 mm; n = 9), maximum width 0.3 mm. Three pairs of radioles with lateral flanges; proximal 1 / 7 of radioles connected by palmate membrane; each radiole with six pairs of pinnules ending with terminal pinnule; all pinnules ending at same height as terminal pinnule. Each radiole with two longitudinal internal cellular supporting axes; each pinnule with one internal cellular supporting axis. One pair of ventral radiolar a ppendages present, nearly as long as radioles, with one internal cellular supporting axis (Fig. 5 B). One pair of elongate dorsal lips present, with neither pinnular nor radiolar appendages; one pair of triangular ventral lips present (Fig. 5 B). Distal end of ventral lobe on anterior peristomial ring bifurcate, extending slightly beyond collar margin (Figs 5 B, 6 A). Posterior peristomial ring collar margin smooth, with small ventral notch (Fig. 6 A). Collar with dorsal gap (Fig. 6 B). Small ciliated patch located on posterior peristomial ring (Figs 5 B, 6 A). One pair of red eyes present on peristomium (not visible in preserved specimens). Glandular ridge on second chaetiger (not visible in preserved specimens). Superior thoracic notochaetae elongate, narrowly hooded, 3 - 7 per fascicle (n = 10; usually 4 - 5 within single specimen) (Fig. 6 C). Inferior thoracic notochaetae bayonet type, 3 - 7 per fascicle (n = 10) (Fig. 6 C). Thoracic acicular uncini 3 - 8 per torus (n = 10); each uncinus with three rows of teeth above main fang; teeth on first row distinctly larger than those on upper rows (Figs 5 C, 6 D). Abdominal uncini quadrangular, with nine rows of teeth above small basal tooth (Figs 5 D, 6 E), 4 - 17 uncini per fascicle (n = 10). Abdominal neurochaetae three in number (two in the smallest specimen, ZIHU 3947) (n = 10), needle-like capillaries in form (Fig. 6 F). Pygidium rounded, with one pair of red eyes; color of eyes faded in preserved specimens. In living specimens, paired statocysts are evident in first thoracic chaetiger; oocytes found in sixth to eighth thoracic chaetigers.	en	Yoshihara, Taiki, Hiruta, Shimpei F., Katoh, Toru, Kajihara, Hiroshi (2012): Three species of Amphicorina (Annelida, Sabellida, Sabellidae) from Japan, with descriptions of two new species.

89564131951997F4BB5389F276D7E942.taxon	distribution	Distribution. Southeastern Australia and eastern Japan; questionably the Mediterranean. At present we have no definitive evidence whether this distribution pattern represents a natural one or has been artificially expanded. If the latter is the case, much more thorough population genetic studies may reveal the native locality and invasion pathways. Incidentally, among sabellids, Sabella spallanzanii (Gmelin, 1791) has been reported to be introduced from European waters to Australia, possibly either via ballast water or hull fouling (Patti and Gambi 2001). The same species has been also reported from New Zealand, introduced either via Australia or directly from Europe (Read et al. 2011). Another sabellid, Branchiomma bairdi (McIntosh, 1885), originally distributed in the Caribbean Sea, was recorded in the southern Gulf of California; hull fouling was considered the most probable vector for the translocation (Tovar-Hernandez et al. 2009).	en	Yoshihara, Taiki, Hiruta, Shimpei F., Katoh, Toru, Kajihara, Hiroshi (2012): Three species of Amphicorina (Annelida, Sabellida, Sabellidae) from Japan, with descriptions of two new species.
