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 The unpublished binomen Gecarcinus festae is a nomen nudum.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).
