A new species of freshwater atyid shrimp, Caridina ngankeeae sp. nov., is described from Hong Kong, southern China. The dorsally armed rostrum, the large number of spiniform setae on the uropodal diaeresis, the relatively long stylocerite and the distally deeply excavated pereiopod 1 carpus indicate a close relationship with the C. serrata Stimpson, 1860 species group and allied species primarily distributed in southern China and northern to central Vietnam. The new species can be distinguished from congeners by characteristics of the rostrum, pereiopods, and male first and second pleopods.
