Caridina gracilirostris gracilirostris: Johnson, 1963: 20   .

Material examined. – Peninsular Malaysia:1 ovigerous female, cl 5.5 mm, ZRC 2007.0368 View Materials , slow, small, tidal stream, draining into Sungai Skudai at mile 7 Johor Bahru, Skudai Road , Malaysia, coll. D. S. Johnson, 10 May 1960   ; Singapore: 7 females, cl 3.5–3.9 mm, ZRC 2007.0369 View Materials , S. Simpungkii at Sembawang Road, Singapore, coll. 11 Jul.1961   ; 2 ovigerous females, cl 5.0– 5.1 mm, ZRC 1979.4.12.146–147, Sungei Seletar at Nee Soon, Singapore, 25 Sep.1959   ; 2 males, 4.0– 4.3 mm, 6 ovigerous females, cl 5.2–5.5 mm, ZRC 2007.0370 View Materials , Sungei Seletar , station 3, Singapore, coll. P. Yeo Kwai Ho, 23 Sep.1959   .

Remarks. – All the specimens examined in the present study have no appendix interna on the endopod of male first pleopod and thus should be referred to the typical form of Caridina gracilirostris   . Cai & Ng (2007) recently revised the C. gracilirostris   species group, referring the form with no appendix interna on the endopod of the male first pleopod to C. gracilirostris   and the other form, with a distinct appendix interna on the endopod of male first pleopod to either C. appendiculata Jalihal & Shenoy, 1998   , or a new species.

Distribution.– Indonesia, Singapore, Malaysia, Thailand, Cambodia, Taiwan, Japan, Palau, the Philippines, Fiji, India and Madagascar (Cai & Ng, 2007)
