Remarks. – Chace (1997) commented that Caridina laoagensis will eventually fall into synonymy with the variable C. weberi De Man, 1892 . Cai & Anker (2004) has shown that C. laoagensis differs markedly from all subspecies of C. weberi and other congeners, and should be regarded as a good species. Caridina laoagensis is characterized by its straight rostrum which is slightly crested basally above the orbit, and the pattern of distal spines and setae on the telson, on which, the median plumose seatae are inserted betweem two lateral spines. This is one of the most common species of atyids in the Philippines .
