Adults and larvae of the very rare Chinese endemic species Acilius sinensis Peschet, 1915 are newly reported from three localities in western Yunnan, which indicates the presence of viable populations in this area. Based on the available data, the rarity of the species in collections is more caused by collecting bias than actual threat of its habitat loss. All larval instars of A. sinensis are for the first time described according to the now generalized larval descriptive format of Dytiscidae, which incorporates detailed chaetotaxic and morphometric analyses. Like other known Acilius Leach, 1817 larvae, A. sinensis is characterized by the typical Y-shaped median process of prementum. So far as the third instar larva is considered, A. sinensis shares with A. fraternus (Harris, 1828), A. kishii Nakane 1963, A. semisulcatus Aubé, 1838, and A. sulcatus (Linnaeus, 1758) the median process of prementum invaginated at nearly 75% of its length compared to less than 35% in A. abbreviatus Aubé, 1838, A. duvergeri Gobert, 1874, and A. canaliculatus (Nicolai, 1822). As far as chaetotaxy is concerned, A. sinensis is distinguished by the presence of the primary pore PAo located on the ventral face of the parietal. The habitat of the species is briefly commented. Acilius sinensis is here newly proposed for inclusion in the IUCN red list in the category Vulnerable.

The genus Cybister Curtis, 1827 is reviewed with respect to the fauna of China. A new species, Cybister (Melanectes) danxiaensis sp. nov. is described and illustrated. Altogether, 16 Cybister species are recorded from China, although the status of two of them remains in question. All species are diagnosed, with their habitus and male genitalia illustrated. Additional faunistic data from China are provided for the following species: C. guerini Aubé, 1838 from Hainan; C. lewisianus Sharp, 1873 from Guangdong and Hainan; C. limbatus (Fabricius, 1775) from Guangdong, Guangxi and Hainan; C. rugosus (W. S. Macleay, 1825) from Chongqing, Guangdong, Hubei, Hunan, Jiangxi, Yunnan, Zhejiang; C. tripunctatus lateralis (Fabricius, 1798) from Chongqing, Guangxi, Jiangxi, Shanghai; C. brevis Aubé, 1838 from Guizhou, Hunan, Zhejiang; and C. sugillatus Erichson, 1834 from Guangxi and Yunnan. An updated identification key and distribution maps for all species are provided. Cybister lateralimarginalis torquatus (Fischer von Waldheim, 1829) is recorded for the first time from Tajikistan and Uzbekistan.

The diving beetle Clypeodytes limpidus sp. nov. is described from western Yunnan, China. It is the second known species of the genus Clypeodytes Régimbart, 1894 from China and belongs to the subgenus Hypoclypeus Guignot, 1950. It can be distinguished from C. bufo (Sharp, 1890), the only other Chinese Clypeodytes species, by the shape of the median lobe, the more rounded body and the elytral pattern. A Chinese specimen of C. bufo is illustrated, and the species is recorded for the first time for Laos.

The species of the genus Dactylosternum Wollaston, 1854 occurring in China and Japan are reviewed. Ten species are recognized to occur in China, two of which were also recorded from Japan. Four new species are described from China: Dactylosternum nanlingensis Mai et Jia, sp. nov. (Guangdong, Jiangxi) from fungal hyphae on fallen wood, D. songxiaobini Mai et Jia, sp. nov. (Guangxi) from fallen wood with termites, D. pseudolatum Mai et Jia, sp. nov. (Guangdong, Hubei, Hunan, Jiangxi, Fujian, Hainan, Yunnan) and D. frater Mai et Jia, sp. nov. (Yunnan) from banana trees. Dactylosternum latum (Sharp, 1873) and D. salvazai Orchymont, 1925 are reported for the first time from China, and species recorded previously (D. abdominale (Fabricius, 1792), D. corbetti Balfour-Browne, 1942, D. hydrophiloides (MacLeay, 1825) and D. pui Jia, 2002) are redescribed or diagnosed. Dactylosternum abdominale (Fabricius, 1792) is confirmed to occur in Japan. Dactylosternum latum is only known from Japan based on type specimens believed to be collected in Nagasaki by G. Lewis in late 19th century; since the species was never re-collected in Japan later, its distribution in Japan seems doubtful. Dactylosternum vitalisi Orchymont, 1925 is synonymized with D. latum (Sharp, 1873), the variability of the latter species is discussed. We moreover found that the type series of D. vitalisi contains two species, with some paratypes actually belonging to D. pseudolatum Mai et Jia, sp. nov. All species of Dactylosternum living in China and Japan are diagnosed and illustrated and a key allowing their identification is provided. We infer that the compact antennal club and paralleled body form are characters related to the life inside of plant tissues, while loose antennal club and rounded body form is present in free living Dactylosternum species. The combination of characters for distinguishing Dactylosternum from other genera of Coelostomatini is also provided.

Abstract A new species of the water scavenger beetle, Regimbartia majorobtusa Mai, Jia, and Jäch sp. n., is described from China (Yunnan) and Thailand (Phitsanulok). It is the eleventh known species of this genus. Regimbartia attenuata (Fabricius, 1801) is redescribed; it is reported for the first time from the Chinese provinces Shaanxi and Hubei. A key to the Chinese species of the genus Regimbartia Zaitzev, 1908 is provided, and the two remaining Asian species, R. minima Orchymont, 1941 and R. sumatrensis Orchymont, 1941, are diagnosed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:992D271C-3327-4706-8625-7662CA4E2EF4

Six new species of Coelostoma Brullé, 1835 are described from China: Coelostoma bannanicum Mai & Jia, sp. nov., C. dactylopunctum Mai & Jia, sp. nov., C. fortunum Mai & Jia, sp. nov., and C. pseudomartensi Mai & Jia, sp. nov. from Yunnan; C. mixtum Mai & Jia, sp. nov. from Fujian; and C. nankunshanense Mai & Jia, sp. nov. from Guangdong. Coelostoma surkhetensis Hebauer, 2002 is a new record from China (Xizang). Coelostoma huangi Jia, Aston & Fikáček, 2014 is reported from Yunnan, C. hajeki Jia, Aston & Fikáček, 2014 from Hunan, C. jaechi Jia, Lin, Chan, Skale & Fikáček, 2017 from Guangdong, C. turnai Hebauer, 2006 from Fujian, Guizhou and Chongqing, and C. wui Orchymont, 1940 from Shanxi and Zhejiang, all for the first time. Coelostoma transcaspicum Reitter, 1906 is excluded from Chinese fauna. Coelostoma sulcatum Pu, 1963 is confirmed as a valid species and its variations of aedeagus are illustrated. The specimens treated as C. wui Orchymont, 1940 by previous authors possibly contain two species. The diversity and habitats of Chinese Coelostoma are discussed. A modified key to the species of Chinese Coelostoma is provided.
