Discussion. According to Garassino et al. (2013), Goneplax rhomboides has a subrectangular carapace with two transverse ridges; well-developed orbits; developed extraorbital spine; dorsal regions not marked; elongated chelipeds. The dorsal characters of the studied specimens, including individuals of different sexes and stages of growth, fit well with the variability of this species. Goneplax rhomboides is reported to date only in the fossil record of Italy from the Miocene to Pleistocene of Piedmont, Emilia-Romagna, Tuscany, Lazio, and Sicily, as reported by many authors (for complete references see Garassino et al., 2013; Baldanza et al., 2017). The species seems to be the most common, wide-spread brachyuran decapod along the Italian Plio-Pleistocene paleo-Mediterranean coast, whereas the extant representatives are widespread in the eastern Atlantic, western Africa, and Mediterranean Sea, burrowing in sublittoral shallow muddy and sandy bottoms from a few to about 100 m deep ( Falciai & Minervini, 1992; Zariquey Álvarez, 1968).
