Remarks Callianassa armata was described from a female of 125 mm from the FijiIslands, while the second specimen was a juvenile female from Ternate, present specimen, being a male, may account for a few discrepancies withthe original description. For example, De Man (1928a) in his key to the speciesof the subgenus Callichirus described the uropodal exopod as lacking a spine —this spine is obviously present in the male. In the latter, the sixth pleonal seg-ment is two and a half times the length of the telson. while in the Fijian femalethis segment is three t
