D277640CE2F0F925DEB1990DC67B0A68.taxon	diagnosis	Diagnosis. Body with deep ventral groove and distinct segments. Prostomium triangular, without eyespots. Peristomium evenly divided into three annulations. Branchial filaments one pair per segment, beginning from third peristomial annulus, and gradually shifting to mid-dorsum between chaetigers 30 - 78; completely shifted branchiae at about one-third distance between notopodium and dorsal midline. Grooved tentacular finalents arising from chaetigers 5 - 6 and occasionally 6 - 7 or 7 - 8. Chaetae including capillaries and acicular spines; notopodial spines 1 - 4, pale brown in color, from chaetigers 16 - 45; neuropodial spines 2 - 4, curved distally, thicker than notoacicular spines, dark brown in color, from chaetiger 24 - 69.	en	Choi, Hyun Ki, Kim, Hana, Yoon, Seong Myeong (2018): Timareteposteria, a new cirratulid species from Korea (Annelida, Polychaeta, Cirratulidae).

D277640CE2F0F925DEB1990DC67B0A68.taxon	description	Description. Holotype: complete, 5.5 cm in length (4.8 - 13.2 cm in paratypes) and 5.7 mm in maximum width (4.0 - 6.0 mm in paratypes), with approximately 261 segments. Body elongated, rounded dorsally, flattened ventrally, with distinct ventral groove throughout and tapering posterior end. All segments distinct, narrow, crowded throughout body with distinct lateral shoulders. Body color in alcohol pale grey to dark grey, branchiae and tentacular finalents yellowish grey; live specimens with body dark red and branchiae and tentacular finalents light orange. No separate pigmentation on body (Fig. 1). Prostomium short, triangular, blunt distally, and as long as three anterior chaetigers. Nuchal organs round, present on posterior-lateral prostomial region. Eyespots absent (Figs 2 A, B, 3 A). Peristomium with three annulations nearly equal in length, longer than prostomium and as long as four anterior chaetigers; second and third annulations with 2 - 3 lateral wrinkles (Figs 2 A, B, 3 A). Branchial filaments one pair per segment, from posterior margin of third peristomial annulus, continuing on most segments except about last ten segments; branchial finalents located just above notopodial ridges in anterior 42 chaetigers (29 - 77 chaetigers in all specimens examined); then shifting gradually to mid-dorsum forming lateral bulge over notopodia from chaetiger 43 (30 - 78 in all specimens examined) to near posterior end; fully shifted branchiae located about one-third distance between notopodium and dorsal midline. (Figs 2 A-C, 3 B). Tentacular filaments formed two transverse groups separated by median gap and arising on dorsum of chaetigers 5 - 6 (6 - 7 or 7 - 8 in some specimens examined); each group with about 18 - 21 finalents arranged in 2 - 3 transverse rows (Figs 2 A, B, 3 A). Parapodia, notopodia forming lateral shoulders dorsally; noto- and neuropodium widely separated throughout (Figs 2 A-C, 3 A, B). Chaetae including capillaries with serrated edge observed under light microscopy (400 x) and SEM observation and acicular spines. Capillary chaetae about 8 - 10 capillaries arranged in two longitudinal rows in anterior parapodia. Notopodial spines nearly straight, pale brown in color, present from chaetiger 40 (16 - 45 in all specimens examined); 1 - 3 spines per segment accompanied by 1 - 3 companion capillaries from chaetiger 40 to posterior end. Neuropodial spines curved distally, slightly thicker than notopodial spines, dark brown in color, from chaetiger 30 (24 - 69 in all specimens examined); 2 - 3 spines per segment with 1 - 2 companion capillaries from chaetiger 30 to very posterior end (Figs 3 C, D, 4 A-C). Pygidium with terminal anus (Fig. 4 D).	en	Choi, Hyun Ki, Kim, Hana, Yoon, Seong Myeong (2018): Timareteposteria, a new cirratulid species from Korea (Annelida, Polychaeta, Cirratulidae).

D277640CE2F0F925DEB1990DC67B0A68.taxon	etymology	Etymology. The epithet of the specific name, posteria, is derived from the Latin posterior, meaning ' hind'. This name refers to the shift in the appearance of the branchial finalents from relatively posterior chaetigers. The gender of the genus name, Timarete, is feminine and the specific name of this new species is designated as feminine.	en	Choi, Hyun Ki, Kim, Hana, Yoon, Seong Myeong (2018): Timareteposteria, a new cirratulid species from Korea (Annelida, Polychaeta, Cirratulidae).
