Thorogobius macrolepis (Kolombatovic, 1891)

Many Large-scaled goby, Gobiidae , were observed and photographed by scuba divers in Southern France (Mediterranean Sea) in 2018: On 13 Apr. 2018, by V. Maran ( Fig. 8C ), at Pointe de la Galère, island of Port-Cros (Var), at 43.0202°N, 6.4091°E, at 34 m depth, one specimen about 6 cm TL ( Maran et al., 2018). On 10 Jun. 2018, by P. Louisy ( Fig. 8D ), at Moyade Island, Marseille (Bouches-du-Rhône), at 43.1764°N, 5.3704°E, 35-36 m depth, two specimens about 6 and 7 cm TL ( Louisy et al., 2019d). On 16 Jun. 2018, by P. Liger, at Petit Mourre, île Verte, La Ciotat (Bouches-du-Rhône), at 3.1573°N, 5.6196°E, at 34 m depth, three specimens about 5 cm TL ( Liger et al., 2019). Sylvain Le Bris also provided 9 more 2018 records of this species in several locations in the Bouches-du-Rhône department, around Marseille (7 Apr., Tiboulen du Frioul; 22 Apr. and 10 Jun., Moyade; 1 May, pointe de Caramassaigne, île de Riou; 9 and 30 Jun., Planier; 21 Oct., Estéou; 1 Nov., Pierre Percée) and in Ensuès-la-Redonne (6 Oct., Erevine Island), between 35 and 42 m depth. In most instances, T. macrolepis was encountered on a coarse sand substrate at, or not far from, the bottom of a rock wall (or sometimes a ship wreck), mostly covered with a coralligenous biocoenosis. Although uncommonly recorded underwater, the species appears locally common in its habitat, often associated with V. dollfusi and G. kolombatovici where these species are present.
