The ist gnathopod resembles most nearly that of africana, Schell., but apparently in the latter the 2nd joint of both gnathopods has neither process nor lobe, and the hand of gnathopod 2 is different.

Undoubtedly the simplest way to deal with these forms is to give specific names to each, rather than to assume local variability on the part of one and the same "species".
