This chapter describes a new species of Caridina H. Milne Edwards, 1837 from the Betsiboka River Basin in Madagascar. This freshwater shrimp is unique in possessing a straight rostrum bearing either 1-14 teeth on the proximal part of the dorsal margin leaving 0.3-3.9 of the distal end unarmed or the entire margin devoid of teeth. When the dorsal margin is devoid of teeth, the new species is similar to Caridina typus H. Milne Edwards, 1837, in its rostral morphology. However, the new species differs from C. typus in possessing a telson with a rounded, protruding posterior margin bearing 4-6 pairs or 7 or 9 spines that increase in length towards the centre and in having ca. 30 eggs of 1.17-1.19 times 0.7-0.8 mm in size.
