In this paper,the material of the genus Ampharete Malmgren,1866 from China Seas(Annelida:Ampharetidae)deposited in the collections of the Marine Biological Museum of the Chinese Academy of Sciences(MBMCAS)is reviewed and previous identifi cations reassessed.In total,four species were found among all specimens examined.Material previously attributed to A.acutifrons(Grube,1860)and A.arctica Malmgren,1866 had been misidentifi ed and is now confi rmed as belonging to A.lindstroemi Hessle,1917 and A.fi nmarchica(Sars,1865),respectively;the presence of A.falcata Eliason,1955 is also confi rmed;A.orientalis(Annenkova,1929)is recorded for the fi rst time from China.

A new species Willenstenhelia mirabilipes sp. nov. （Copepoda： Harpacticoida： Miraciiidae） is described based on specimens collected from the South China Sea. This is also the first report of the genus Willenstenhelia from the China seas. The new species differs from congeners by the combined characters： all somites without spinules on surface except anal somite; third segment of female P4 exopod with two inner setae; female P5 baseoendopodal lobe with four elements and P5 exopod with sharp apical spine; caudal ramus about six times as long as broad.

A new species of the family Pheronematidae is described in this study. Specimens were collected at Yap seamount and Caroline seamount in the Northwest Pacific Ocean. Poliopogon distortus sp. nov. contains oval macramphidiscs, three categories of amphidiscs, clavate monaxons and sceptres, making it distinguished from the eight known congeners easily. This is the fourth record of genus Poliopogon from the Northwest Pacific Ocean. We also used a partial sequence of 16S rDNA gene to confirm the family assignment of the new specimen.

A new record of the ampharetid genus Auchenoplax, A. worsfoldi Jirkov and Leontovich, 2013, is reported and described from the East China Sea. The specimens agree well with the original description of Auchenoplax worsfoldi with two pairs of branchiae, two thoracic uncinigers with enlarged neuropodia and 12 abdominal uncinigerous segments. The present specimens have long and filiform branchiae extending to thoracic chaetiger 9, which was not included in the original description. This is the first record of this species in Chinese waters.

Sabaco sinicus sp. nov. is described based on material collected from Chinese coast. It has been misidentified as Asychis gangeticus Fauvel, 1932 since Uschakov and Wu （1962）. Here, we recognized it as a new species based on combination of the following characters： dark-brown pigmentation spots on nuchal grooves and first three chaetigers; glandular pattern on chaetigers 4-6; preanal achaetigerous segments absent; anal plaque trumpet- shaped with a disc-shaped dorsal lobe; notochaetae consisting of geniculate capillaries and fine capillaries with or without spinose spiral bands; neurochaetae presented as a single row of rostrate uncini. Asychis gangeticus differ from the new species in having no pigmentations on body and a triangular dorsal lobe of anal plaque. Distribution region of this species have moved northward significantly from sea area south of Changjiang Estuary since the 1950s.

Based on polychaete specimens collected from coastal areas of China in 1959, a new species of the family Orbiniidae, Leodamas sinensis sp. nov. is described in the present paper. The new species can be distinguished from its cogeners by the combination of following characters： branchiae present from chaetiger 5; each thoracic neuropodial postchaetal lobe possessing broad tori, with a digital to triangular-shaped papilla at its midlength; 4 or 5 vertical rows of uncini and one posterior row of accompany capillaries in thoracic neuropodia; acicula present in both abdominal notopodia and neuropodia, slightly or distinctly projecting. A key to all known species of the genus is provided.

A new species belonging to the genus Haloschizopera Lang, 1944 (Copepoda, Harpacticoida, Miraciidae, Diosaccinae) was identifi ed based on the samples collected from the East China Sea, near the off shore of Zhejiang Province, East China. The new species is closely related to H . pygmaea Norman & Sccot T., 1905 and shares a combination of the following features: A1 eight-segmented;A2 exp-2 with one distal seta, exp-3 with three setae;P1 endopodal segments subequal, enp-1 not exceeding exp-2;exp-3 of P3 with one inner seta, of P4 with two inner setae. The new species is characterized by the presence of one inner seta on P2 exp-3 of both sexes. It can also be distinguished from its congeners by the characters of female: P5 exopod subcircular, endopodal lobe extending beyond half-length of exopod;genital doublesomite ornamented with three dorsolateral rows of spinules on anterior part.

The genetic basis for bivalves＇ adaptation and evolution is not well understood. Even few studies have focused on the mechanism of molluscan molecular evolution between the coastal intertidal zone and deep-sea environment.In our studies, we first conducted the transcritpome assembly of Modiolus modiolus mussels living in coastal intertidal zones. Also, we conducted transcriptome comparison analyses between M. modiolus and Bathymodiolus platifrons living in hydrothermal vents and cold methane/sulfide-hydrocarbon seeps. De novo assemblies of the clean reads yielded a total of 182 476 and 156 261 transcripts with N50 values of 1 769 and 1 545 in M. modiolus and B. platifrons. A total of 27 868 and 23 588 unigenes were identified, which also displayed the similar GO representation patterns. Among the 10 245 pairs of putative orthologs, we identified 26 protein-coding genes under strong positive selection（Ka/Ks〉1） and 12 genes showing moderate positive selection（0.5
