Additional fauna of Coelostoma Brulle, 1835 from China, with re-establishment of Coelostomasulcatum Pu, 1963 as a valid species (Coleoptera, Hydrophilidae, Sphaeridiinae).

ABSTRACT: Six new species of Coelostoma Brullé, 1835 are described from China: Coelostomabannanicum 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. Coelostomasurkhetensis Hebauer, 2002 is a new record from China (Xizang). Coelostomahuangi 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. Coelostomatranscaspicum Reitter, 1906 is excluded from Chinese fauna. Coelostomasulcatum 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.

Project description:The cosmopolitan subfamily Acidocerinae (Coleoptera: Hydrophilidae) is one of the largest and most taxonomically challenging lineages of water scavenger beetles. Recent phylogenetic studies have substantially advanced our understanding of acidocerine relationships but also illuminated the twin challenges of poorly delineated generic concepts and a classification broadly incompatible with the phylogeny. Here, these two challenges are addressed by providing a comprehensive synthesis and taxonomic tools for the Acidocerinae, including (1) a brief history and the current state of acidocerine classification, (2) a review of acidocerine ecology and collection methods, (3) the current knowledge of larval and fossil acidocerines, (4) a morphological primer on characters of taxonomic and systematic importance within the lineage, (5) a key to the world genera of Acidocerinae, (6) diagnoses, habitus, and aedeagal images, distribution maps, and summary of knowledge for each of the 23 extant genera in the subfamily, and (7) a complete annotated taxonomic catalog including the published distributions, synonyms, and references for all described 541 acidocerine species recognized as of 1 April 2021. The following nomenclatural acts are proposed to bring the phylogeny and classification into alignment: Colossochares gen. nov. is established to accommodate two African species previously described as Helochares (s. str.); Novochares gen. nov. is newly established to accommodate 15 Neotropical species previously included in Helochares (s. str.); the remaining Helochares subgenera Helocharimorphus Kuwert syn. nov. and Hydrobaticus MacLeay syn. nov. are synonymized with Helochares Mulsant. Peltochares Régimbart sensu nov. is redefined to include eight Old World species previously included in Helochares (s. str.). A lectotype is designated for Peltochares conspicuus Régimbart, the type species of the genus. The taxonomic and morphological circumscription of Helochares sensu nov. is narrowed and redefined.
