REMARKS

Actually Nobili never published a description of Gecarcinus festae . In 1901 he described Sesarma festae and Uca festae and in the same paper referred to two specimens of Gecarcinus collected in Ecuador as Gecarcinus ruricola , a species restricted to western Atlantic islands ( Türkay 1970; Perger & Wall 2014). The abovementioned specimen, with the name of Nobili (1901) on the label, was likely collected by Enrico Festa during his 1895-1898 trip to Ecuador (Viaggio del Dr. Enrico Festa nella Republica dell’Ecuador et regioni vicine), then studied by Nobili who probably first considered it as new and dedicated to Festa as “ Gecarcinus festae ” without finally establishing it. The unpublished binomen Gecarcinus festae is a nomen nudum. The MNHN specimen examined by Nobili and selected as paratype of the new species Gecarcinus nobilii dedicated to Nobili by Perger & Wall (2014) is figured in their fig. 3D-F. The holotype is preserved in LACM.

Furthermore, Pacific Gecarcinus (Gecarcinus) lateralis quadratus sensu Türkay (1970: 338 ; see Prahl & Manjarrés 1984: 155) and Gecarcinus lateralis sensu Türkay 1987 (: 147, fig. 7) have been referred to as Gecarcinus nobilii Perger & Wall, 2014 . Note that Gecarcinus quadratus Saussure, 1853 was recently recognised as a valid species ( Toledano Carrasco & Villalobos Hiriart 2018).
