A single ephippial female and a single male were found in autumn in an artificial lake (A34). The first record for China . Species is known from Thailand , Laos and Vietnam , rare, usually recorded from streams and rivers (Sinev 2016). It is also the first record of the ephippial female for this species. In the preserved specimen, ephippium is weakly yellow-brown, covered by minute, irregularly spaced dots. Distinctive characters of the species include characteristic shape and armament of postabdomen in both sexes with strongly protruding preanal angle (fig. 7 F, I); IDL setae of thoracic limb I armed with uniform thin spinules in both male and female (fig. 7 H, J); antenna with a cluster of very long setulae on basal segment of exopodite (fig. 7 G). Studied specimens differ from those recorded from South-East Asia by having a less protuberant preanal angle of the postabdomen and somewhat longer antennal spines.
