Abstract. A very diverse ostracod fauna was discovered in the latest Permian strata of the Dongpan section, southwestern Guangxi, South China. Fifty-one species belonging to twenty-eight genera were identified and described, including two new species (Bairdia dongpanensis n. sp. and Spinomicrocheilinella anterocompressa n. sp). This type of assemblage, with nineteen palaeopsychrospheric species and four pelagic species, is the first world-wide deep-water ostracod fauna reported from the latest Permian strata and the first one recorded in the Permian of China. The palaeoenvironmental analysis allows one to propose an evaluation of the bathymetry variation along the Dongpan section.

Four species ofLaonice(Annelida: Spionidae) were collected from the lower bathyal depths (3300–3700 m) in the Whittard Canyon, NE Atlantic. Two are herewith described as new species:Laonice whittardensissp. nov. andLaonice nataesp. nov. The other two areLaonice blakeiSikorski & Jirkov, 1988 andLaonice magnacristataMaciolek, 2000.Laonice whittardensishas genital pouches appearing from chaetiger 3, prostomium free of peristomium and bidentate hooks.Laonice nataebelongs to the subgenusAppelloefianov. with prostomium distinct from the peristomium, more than two vertical rows of capillaries in several anterior chaetigers, genital pouches present on a limited number of segments or totally absent. However, the absence of pronounced anterior widening of the body together with anterior branchiae, which are remarkably (nearly twice) longer than the notopodial postchaetal lobes, the narrow lanceolate notopodial postchaetal lobes, the pronounced pointedness of all postchaetal lobes (both notopodial and neuropodial) in the anterior half of body at least, and absence of genital pouches and the size of the body all distinguishL. nataefrom other species belonging to this subgenus. An identification key to all nine known deep-water (>400 m depth)Laonicespecies in North Atlantic is given and four previously recognized sub-generic groups are formally named:Laonice, Sarsianasubgen. nov.,Appelloefiasubgen. nov.,Norgensiasubgen. nov.

Two New Species

Two new species of Lohmanniidae, Papillacarus (Papillacarus) retinervius sp. nov. from soil in Hainan Province, South China and Papillacarus (Papillacarus) mammilatus sp. nov. from moss and soil in Guizhou Province, Southwest China are described and illustrated. Papillacarus (P.) retinervius sp. nov. is most similar to Papillacarus (P.) polygonatus (Ermilov & Anichkin, 2011), however, it can be distinguished from the latter by the following characterstics: 20–21 pairs of additional neotrichal setae, setae d2, e2, h1, p1 shorter, as long as d1, epimeral setal formula 10-8-4-3. Papillacarus (P.) mammilatus sp. nov. is most similar to Papillacarus (P.) angulatus (Wallwork, 1962), however, it can be distinguished from the latter by the following characterstics: transverse bands S3 complete, eight pairs of subcapitular setae, epimeral setal formula 10-6-3-4.

The genus Pachyodes Guenée, 1858 is reviewed, and two new species are described: P. novata, sp. nov., from South China and P. jianfengensis, sp. nov., from Hainan Province, China. The six previously known species are redescribed, and a lectotype is designated for P. pratti (Prout, 1927). Illustrations of adults and genitalia are presented. The holotype and paratypes of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China.
