Distribution

In Vietnam, this species is distributed in the mountainous areas of the northeast and some parts of northwest Vietnam (Fig. 1 d). In China, the species occurs in the following Provinces: Hubei, Jiangxi, Fujian, Guangdong, Guangxi, Guizhou, Anhui, Zhejiang ( Liang 2004); and Hong Kong.

Ecology

Living in mountain streams and based on egg-size, this species can be considered a land-locked species (Table 1 ).

Taxon discussion

Dang (1967) described Caridina denticulata vietnamensis from northern Vietnam. In subsequent publications, he raised this subspecies to species level as C. vietnamensis ( Dang 1975, Dang et al. 1980). Cai (1996) synonymised it with Neocaridina palmata palmata (Shen, 1948). Subsequently, Dang and co-authors moved it to the genus Neocaridina ( N. vietnamensis ) ( Dang and Do 2007b, Dang and Do 2008, Dang and Ho 2012). Li and Liang (2002) followed Cai (1996) to consider C. denticulata vietnamensis as junior synonyms of Neocaridina palmata palmata (Shen, 1948). However, Dang and Do (2008) and Dang and Ho (2012) stated that N. vietnamensis can be distinguished from N. palmata or a subspecies of this species by the endopod of the male first pleopod (round shape and stable vs. variable); appendix masculina of male second pleopod (perpendicular vs. rounded) and appendix interna (reaching nearly to the tip of appendix masculina vs. not reaching to the tip of appendix masculina) and larger egg size (1-1.25 × 0.65-0.85 mm) ( Dang and Do 2008, Dang and Ho 2012). These authors also mentioned the differences in the endopod of the first pleopod and the appendices masculina and interna. Nevertheless, Liang (2004) stated that the shape of the endopod of the first pleopod is very variable in N. palmata , even in the specimens collected from the same localities. According to this author, N. palmata can be distinguished from N. denticulata De Haan, 1849 by the third pereiopod. In both sexes, it differs in length and shape (vs. length and shape of third pereiopod being similar between male and female); the dactylus and distal portion of the propodus of the third pereiopod of male is inflated (vs. the dactylus and distal portion of the propodus of the third pereiopod of the male is not inflated); the propodus of the third pereiopod of the male is curved (vs. the propodus of the third pereiopod of the male is straight). He also noted that this species lives in streams, rivers, reservoirs, ditches and small ponds. It is distributed in the middle reaches of the Yangtze River and central China, south and southwest China and North Vietnam. Due to its wide distribution, humid climate and different living environments, the appendix masculina often shows morphological variation and subspecies differentiation. Our specimens collected from different sampling sites in northeast Vietnam showed that all of them belong to the subspecies N. palmata palmata .
