Remarks:

Previously reported from this island by Cai and Shokita (2006) [ 12] and by Chace (1997) [ 20] under the name Caridina longirostris . de Mazancourt et al. (2018) [ 54] and Cai (2020) [ 55] recently re-described this species in detail. In contrast to the findings of Cai and Shokita (2006) [ 12] and Cai (2020) [ 55], male specimens of this species have been found with a fully developed appendix interna on their endopod of the first pleopod. This character should thus be used with caution when identifying species of the C. nilotica group.

This species has been assessed as Least Concern for the IUCN Red List (Cai et al., 2013) [ 57].
