Colour. Adult Paramola macrochira are orangish-brown overall ( Ahyong et al., 2009: figs. 78, 79). The smaller specimens obtained from the South China Sea are pale orangish-pink overall, with the ambulatory legs mostly white ( Fig. 24C, D ).

Remarks. On the juveniles of this large species, the rostral horns appear to be relatively longer than in the adults. Ng (2015) demonstrated that the Paromola alcocki faughni from Serène & Lohavanijaya (1973) is a juvenile of P. macrochira .
