Diagnosis

Centropages orsinii Giesbrecht, 1899 and C. halinus are the only species in the genus with 2-segmented endopods on legs 1 to 3. These species are also similar in having the posterior margins of the prosome drawn into blunt, nearly symmetrical points, a character shared by only one other species, C. sinesis. Chen and Zhang, 1965. C. halinus differs from C. sinensis in that C. sinensis females have a large asymmetrical lobe on the genital complex in dorsal view, and males have the right leg with two terminal processes, as opposed to only one in C. halinus. The genital complex of the female of C. orsinii has a ventral spiniform process not present in C. halinus, and the leg 5 exopod is more robust. Males of C. orsinii have a long terminal process on the left leg 5 exopod 2, whereas C. halinus, has a short spine.
