Ampharete goesi brazhnikovi Annenkova, 1929 View in CoL (type: ZIN 1/30254 and 2/30255); type locality: Sea of Okhotsk southern Sakhalin, 10–12 fms); Uschakov, 1955: 369, fig. 137Ж.

MATERIAL: two syntypes.

DESCRIPTION. The subspecies has been described by two syntypes. Description of the syntype 1/ 30254. 29 mm long. The thorax dissected on the entire length of the dorsum. Oral tentacles losted. Paleal chaetae: on the left, all are cut off at the root, on the right side 15 chaetae, most of them broken off, they much longer and thicker than the most developed notochaeta, they go forward beyond the anteri- or margin of the prostomium; several preserved chaetae have tips ( Fig. 15F, G View Fig ) as in other species of the superspecies, including A. goesi s.str. The branchial groups without medial gap. The places of branchostyles attachment of the three branchophores form almost in a straight line, the 4th (3rd outside) between the 2nd and 4th distinctly behind them; this branchophore is clearly associated with the notopodia TC2 (= CT6). Caudal to the bases of the medial branchophores a pair of small nephridial papillae. Branchostyles missing. 14 TC, 12 TU. 16 AU.Abdomen with very small rudimentary notopodia, neuropodia without cirri. Pygidium with two moderate-length lateral cirri and numerous low papillae. The tube missing. All the parapodia intact, so the drawings of the chaetae illustrating the original description are not made from this syntype, but from a lost fragment of the 2/30255 syntype, which, judging by the shape and number of the paleal chaetae slowly tapering in filiform tips, does not fit original description, it belongs to other species, probably A. crassiseta , but it is not in a good condition, so cannot be identified with certainty.

REMARK. There is no reason to accept this subspecies as valid.
