The genus Gobio in France, with redescription of G. gobio and description of two new species (Teleostei: Cyprinidae)
The gudgeon Gobio gobio is redescribed and a neotype is designated. The type locality is stream Sieg at Eitorf, in the Rhine drainage, Germany. Two new species are described from France: G. alverniae from the upper Dordogne, Garonne and Loire drainages (Massif Central) and G. occitaniae from southern drainages (from Vidourle to Tech on Mediterranean slope, from Eyre to Charente on Atlantic slope). Gobio lozanoi is redescribed based on material from Adour drainage. These species are distinguished by a combination of lateral line and transverse scale counts, presence or absence of scales on breast, shape of pelvic axillary scales, shape and width of interorbital area, shape of mouth, and details of colour pattern.
