It is virtually impossible to visually distinguish specimens of Trapania hispalensis from Trapania tartanella, despite a radular analysis allows to differentiate them perfectly, according to the scheme published at Bill Rudman’s Sea Slug Forum and that we reproduce here:

  • Trapania. Bernard Picton considers that this word derives from Greek “Drepane” meaning “sickle” or “reaping hook”, presumably referred to the appendixes located in the base of rhinophores and gills in the genus Trapania.
  • Hispalensis, from “Hispalis”, the name of the city of Seville in Roman times, which in turn is the Latinization of “Spal” or “Ispal”, the name of the Turdetani (successors to the people of Tartessos) village on which the Romans settled.
