Freshwater Cladocera (Crustacea, Branchiopoda) in Lake Tonle Sap and its adjacent waters in Cambodia

Abstract

Sixty species of freshwater Cladocera (Crustacea, Branchiopoda) are recorded from Lake Tonle Sap and its adjacent waters, Cambodia. Four species, Ceriodaphnia laticaudata, Bunops cf. tuberculatus, Leydigia australis, and Chydorus cf. dentifer are newly recorded from Southeast Asia, and occurrence of Macrothrix pholpunthini is secondary confirmed in the world. The present cladoceran fauna is characterized by having rich epiphytic and benthic forms. It can be associated with the shallow and vegetation-rich habitats of the study sites.

Cladocera (Crustacea: Branchiopoda) of Vientiane province and municipality, Laos

“…Described from Syria (Richard, 1894) as Pleuroxus, then moved to a special genus Ephemeroporus (Frey, 1982b) and found to be tropicopolitan (Smirnov, 1996;Kotov et al, 2011. It is widely distributed in other SE Asian countries (Maiphae et al, , 2008Tanaka and Ohtaka, 2010;Korovchinsky, 2013a). Maiphae et al (2005Maiphae et al ( , 2008 identified three other species of the genus Ephemeroporus from Thailand, but all our populations were similar to Ephemeroporus barroisi.…”

“…Leydigiopsis sp. This is apparently a new taxon, rare yet occuring in different countries of the Oriental region (Sanoamuang, 1998;Maiphae et al, 2005;Tanaka and Ohtaka, 2010;). The species is described by Van Damme and Sinev (2013).…”

“…Described from the Pearl river in SE China (Kiser, 1948) as Alona and then translocated to the genus Nicsmirnovius . There is a single species in the Oriental zone, N. eximius, which occurs in different SE Asian (Idris, 1983;Kotov and Sanoamuang, 2004a;Tanaka and Ohtaka, 2010;Korovchinsky, 2013a) and South Asian countries (Chatterjee et al, 2013), but being a rheophilic species it is not very common in littoral sam- …”

“…There were only a few publications concerning the Cladocera fauna of other countries (Tanaka and Ohtaka, 2010), sometimes outdated (Shirota, 1966;Thanh et al, 1980). Korovchinsky (2013a) summarised the available information on the SE Asian cladocerans and concluded that among 297 formal species recorded from SE Asia, only 67 species could be regarded as good, while others are junior synonyms or taxa with unclear or/and unconfirmed status in SE Asia.…”

Cladocera (Crustacea: Branchiopoda) of Cat Tien National Park, South Vietnam

“…The faunistic composition of the group was re-evaluated for Thailand (Maiphae et al, , 2008 and local faunas were investigated in some regions of Thailand, Cambodia and Laos (Pholpunthin, 1997;Sanoamuang, 1998;Korovchinsky and Sanoamuang, 2008b;Tanaka and Ohtaka, 2010;Kotov et al, 2013). Several taxonomic groups were revised, and several new species were described Sanoamuang, 2008a, 2008b;Korovchinsky, 2011;Sanoamuang, 2004a, 2004b;Sinev, 2011Sinev, , 2012Sanoamuang, 2007, 2011;Sinev and Kotov, 2012;Van Damme and Sinev, 2013;.…”
