Distribution

Habitat

Freshwater in rivers and ponds.

Remarks

Our genetic study shows that Caridina richtersi Thallwitz, 1891 and C. spathulirostris Richters, 1880 are conspecific and we consider the former to be a junior synonym of C. spathulirostris. The specimens of this species are polymorphic in the shape of the rostrum and the chelipeds, which led to the description of numerous forms like C. spathulirostris f. rectirostris, C. spathulirostris f. curvirostris, C. richtersi f. typica, C. richertsi f. apiocheles. This kind of variability was also described in another endemic species of Caridina from the SWIO, C. similis (see Marquet & Keith, 2008).
