Synalpheus nobilii was first described from St. Helena, Ecuador by Coutière (1909). For more details, see Chace (1962), Abele (1975). This species is named after Dr. Joseph Nobili, the carcinologist. Types stored at the Muséum national d’Histoire Naturelle, Paris, France (MNHN).
This species has been collected from coral and coral rubble (Abele 1975), from beneath tufts of coralline algae in the shallow subtidal (Hendrickx 1983), among rocks, tubes, and sponges (Wicksten 1996); from the intertidal to ~31 m depth.
Maximum body size is 7 mm carapace length (Chace 1962, Clipperton Island). Morphologically similar to S. fritzmulleri, but differs in the more massive carpus of the minor chela and by other features of the pereopods (Coutiere 1909). Body color translucent olive green or reddish brown, with dark-tipped chelae and a translucent orange fringe on the tail fan (Rocas Alijos: Wicksten 1996).
