Remarks

Cai and Shokita (2006) recently discussed the taxonomy of Caridina serratirostris and C. celebensis , and pointed out that ‘‘In Ryukyus, specimens with short rostrum are mostly of C. celebensis , while those with long rostrum, almost all having arthrobranch on the first pereiopod, are of C. serratirostris .’’

Distribution

Japan, Philippines, Fiji, Malaysia, Indonesia and Madagascar.
