REMARKS

As indicated elsewhere (Bleeker et al. 2023: 438, key), Pherecardites Horst, 1912 resembles Eurythoe Kinberg, 1857 by having branchiae from chaetiger 1. These genera differ in that in Pherecardites the caruncle has a median ridge with up to four digitate lobes and spurred neurochaetae with denticles along the inner side, whereas Eurythoe has a caruncle with a median ridge concealing lateral plates but without lateral digitate lobes, and its spurred neurochaetae lack denticles. Horst (1912: 33) regarded Pherecardites as “intermediate between Hermodice and Pherecardia, its ventral bristles resembling those of Hermodice, the dorsal ones those of Pherecardia .”; however, the caruncle of the members of these two genera differ. In Pherecardites the lateral lobes are digitate and smooth, whereas in Pherecardia the lateral lobes are foliose and pinnate.
