Renoult on 10 Jan 2019 , at L’Herbaudière, Noir- moutier ( 47.0189°N , 2.3035°W ), in a tide pool. It measured roughly 3 cm TL. The present individual represents the fifth record of the species south of the Loire River estuary. The species was previously recorded once in 1927, twice in 1975 off Gironde estuary ( Cuenot, 1927 ; Cazaux et al. , 1975 ; Chapoulie, 1975 ) and once again on 10 Sep 2008 , off Charente Maritime at 46.2333°N , 1.4333°W ( Quéro et al. , 2009 ). Scarcity of records could be mostly related to its cryptic habitat and small size making its observations rare. The species is commonly observed inside the hollow holdfast of the seaweed Saccorhiza polyschides Batters, 1902 in Brittany at 0-10 m depth.
