Micrenophrys lilljeborgii (Collett, 1875) View in CoL
A Norway bullhead, Cottidae ( Fig. 4G View Figure 4 ), was collected by S.P. Iglésias on 30 Oct. 2018 while underwater fishing for the shrimp Palaemon serratus (Pennant, 1777) with handnet about 20 m off the beach of Trévignon (Tregunc, Finistère, France), at 47.8002°N, – 3.8534°W, at 3 m depth during low tide. The specimen measured 36 mm TL, 29 mm SL, 11.5 mm HL and weighed 0.76 g. D1: V; D2: I+10; A: 8; V: I+2; P: 15. The specimen was collected on a shady gra- nitic wall colonized by a thin layer of filamentous seaweeds and the large gorgonians Eunicella verrucosa (Pallas, 1766) , with presence of individuals of P. serratus and Tripterygion delaisi Cadenat & Blache, 1970 . The specimen was preserved with the collection No. MNHN-IC 2020-0094 and a tissue sample was preserved under No. BPS-4218. The unusual first dorsal fin for this specimen (5 ray counts instead of 8-11), very small and starting well behind the edge of operculum (when it normally starts before it) is viewed as a teratological character. It is the first record for Finistère and the 6 th record for French waters. The five previous French records were estimated from ~ 4 to 8 cm TL, they were observed from 9 Sep. 2010 to 6 May 2016 in coastal waters of Côtes d’Armor and Morbihan (Brittany, France), from intertidal area to 15 m depth ( Limouzin et al., 2015a, 2016, 2017; Gully et al., 2016). These records represent a southern extension of the known distribution range for the species. Rather than signifying a recent range expansion, these records more likely indicate past confusions with juveniles of Taurulus bubalis (Euphrasen, 1786) or Myoxocephalus scorpius (Linnaeus, 1758) . For instance, a 3 cm long specimen of this species was wrongly identified as a juvenile T. bubalis by Louisy (2005, 2015); it was photographed in Ploumanach (Côtes d’Armor, northern Brittany) in August 1998, on an overhanging wall at 20 m depth.
