Remarks

Macrobrachium mirabile was originally described by Kemp (1917) on the basis of specimens from Myanmar (Yangon and Moulmein) and the Gangetic Delta, India. The species is also known from Borneo (Holthuis, 1950; Ng, 1995). Suvatti (1937) recorded this species from Chao Phraya river, Pakret and Paknam, central Thailand. Naiyanetr (1998) listed one more locality, Chachoengsao, in eastern Thailand. The present record is from Ranong, south Thailand. As already stated by Kemp (1917: 230) and Chace and Bruce (1993: 34), this species should perhaps be better placed in its own genus. This matter is now being examined by A. J. Bruce and D. Wowor (personal communication). No male specimens are known from Thailand. A rediagnosis was recently given by Cai and Ng (in press) on the basis of this material.

The species is distributed in Gangetic Delta (Kemp, 1917), Myanmar (Kemp, 1917), Thailand (Suvatti, 1937) and Borneo (Holthuis, 1950; Ng, 1995).
