<strong>Annotated Checklist of Chinese Cladocera (Crustacea: Branchiopoda). Part II. Order Anomopoda (families Macrotrichidae, Eurycercidae and Chydoridae)</strong>

Abstract

About 114 "species" of Macrothrichidae, Eurycercidae, and Chydoridae (Cladocera, Anomopoda), belonging to 39 genera, have been reported from China, with 14 species in 6 genera in Macrothrichidae, 2 species in one genus in Eurycercidae, and 98 species in 31 genera in Chydoridae. In total, 203 species in 62 genera, 13 families and 4 orders have so far been reported from the country. Of these, 187 are tentatively considered as valid, while 16 are incertae sedis. In reality, many records hide taxonomic problems that remain to be settled. Up to 10 percent of this fauna might be endemic at the species level, but we expect this number to increase pending new, comprehensive studies. No endemic genera fall to be recorded. Most of the several hundreds of taxonomic or biogeeographic papers from which this information was extracted suffer from poor or outdated taxonomy, such that up to half of all species are up for re-evaluation. Detailed morphological examination, but also provoked male production, especially in chydorids, are ways to improve identifications and should be stimulated. On the other hand, the inventory is certainly still incomplete with several tropical-subtropical taxa still to be expected in China. The extreme south and islands are among promising sites that remain to be explored, as well as extreme habitats all over the country. Molecular studies in China started around the beginning or the present decade, and should be multiplied.

Revision of the costata-group of Alona s. lato (Cladocera: Anomopoda: Chydoridae) confirms its generic status

“…nov., while widely distributed in the West Palearctic, is confined to dystrophic sphagnum bogs in coniferous forests and mountain belts. Species of the rustica-clade have never been recorded in China (Chiang & Du 1979;Ji et al 2015), South-East Asia (Korovchinsky 2013), India (Chatterjee et al 2013) or Australia (Smirnov & Timms 1983). In contrast, the costata-clade is distributed worldwide, and includes at least four wide-ranging species: Palearctic F. costata s.s. comb.…”

Winter-Spring fauna of Cladocera of Dali Bai Autonomous Prefecture, Yunnan Province, China

“…W2, W6, W7). Widely distributed Palearctic species, rare in China, with few records in Taiwan, Wuhan, Jiangxi, Yunnan (Xiang et al, 2015), and in Xinjiang (Chertoprud et al, 2017). Studied specimens (Fig.…”

“…The Cladocera of East Asia have been actively investigated during the last decades. Local faunas were recently studied in Far East of Russia (Kotov et al, 2011ab), South Korea (Kotov et al, 2012(Kotov et al, , 2017Jeong et al, 2014) and China Chertoprud et al, 2017) and numerous new taxa were described from the region Korovchinsky, 2009;Kotov & Sinev 2011;Jeong et al, 2012Jeong et al, , 2013Jeong et al, , 2017 Checklists were published for Korea (Jeong et al, 2014) and China (Xiang et al, 2015;Ji et al, 2015). But most regions of continental China are not yet well studied, with most faunistic data for the country based on ecological work with doubtful identifications (Xiang et al, 2015;Ji et al, 2015).…”

“…No data for other large water bodies in Dali area are available. While records for Yunnan cladocerans in general are numerous (see Xiang et al, 2015;Ji et al, 2015), only few records refer specifically to Dali Area.…”

An annotated checklist of the freshwater cladocerans (Crustacea: Branchiopoda: Cladocera) of Ecuador and the Galápagos Islands

“…Recently, several comprehensive checklists with taxonomical notes have been compiled for different countries where cladocerans are under intense study, e.g. India (Chatterjee et al, 2013), China (Korovchinsky, 2013;Ji et al, 2015;Xiang et al, 2015) and Korea (Jeong et al, 2014) in Asia; Colombia (Kotov, Fuentes-Reinés, 2015), Chile (De los Ríos Escalante, Kotov, 2015) and Brazil (Elmoor-Loureiro, 1998, 2018 in South America. At the same time, large revisions and checklists in Cladocera genera have helped to tackle taxonomical challenges (e.g.…”
