REMARKS

Baird (1868: 229) indicated that A. formosa de Quatrefages, 1866 does not belong in Amphinome . Yáñez-Rivera & Salazar-Vallejo (2011: 252, table 1) regarded this species as belonging in Pherecardia based on the caruncle features. The caruncle was originally described as foliose and very large, reaching segment 4, oval with 7-8 lobes connected mid-dorsally to a median ridge. De Quatrefages (1866: 400) also indicated that neurochaetae were smooth, lacking denticles or a fang. As the pigmentation was not described and the type material is lost, it is not possible to assign this species within Pherecardia . Because there is no type material, and because the original description is incomplete, and no illustrations were provided, its status cannot be determined. Further, there were no details about dorsal pigmentation nor any color indicated for notopodia, and this explains why we are unsure about which species it might be conspecific with.
