Remarks. – When discussed the subspecific status of Caridina brevicarpalis brevicarpalis and C. b. endehensis, Chace (1997: 8) noted that in the latter subspecies, “(t)he rostrum, suborbital angle, and posterior spines of the telson are very different from those in the typical form of C. brevicarpalis that the identification of these specimens as subspecies of that species is justified only because of the desirability of avoiding name changes until taxa are studied more intensively.” On the basis of more specimens available, the differences between these two forms are always distinct, and could be easily used to separate one from the other, even in some cases, two forms are found together. We hereby treat both as distinct species. This is the first record of the species for Philippines.

Distribution. – Sulawesi, Fiji, Philippines.
