Remarks. – Macrobrachium jaroensis is characterized by the presence of the dense stiff setae at the cutting edges of the fingers, and the variable length of fingers, which are from shorter than palm to distinctly longer. It was originally described from Leytes, Philippines. Hwang & Yu (1982) reported it from Taiwan. Chace & Bruce (1993) recorded it from Cebu. The present study shows that it is quite common in the Philippines. Shy & Yu (1998) doubtfully referred some Taiwanese specimens to M. jeroensis . The re-examination of the Taiwanese specimens by the first author confirmed this identity.

Distribution. – Philippines, Taiwan.
