Remarks.

P. candidoi and P. fluminensis ( Krøyer, 1844) are sympatric species, very frequent in depths between 10 and 100 m. These are the commonest species of Pallenopsis along the Brazilian coast. The two species are very similar, varying mainly in the number of setae on the legs (larger and more numerous in P. candidoi ) and in the number of articles in the female oviger, in which article 6 is smaller than article 5 and 8 and is less than half as long as article 7 in P. candidoi (article 6 is the same size as article 5 and article 8 is almost the same size as article 7 in P. fluminensis ) ( Marcus 1940; Mello-Leitão 1949; Stock 1974; Lucena et al. 2017).
