NOTES: The recent record of C. fluviatilis in two freshwater rivers in the Indian sub-continent ( Kamiya et al. 2016) consitute a remarkable geographic range extension in the old world after its original discovery from a stream in Panama, Central America (Kravesky et al. 2011). In an earlier study ( West et al. 2015), specimens collected from the same two localities above were assigned to C. beccarii , but with an observation that ”molecular evidence (28S rDNA and rbc L) placed the Indian specimens close to C. beccarii and C. fluviatilis ”. A subsequent comparative study of the type material and molecular data on specimens from Europe placed the Indian specimens indisputably in C. fluviatilis .
