AbstractMarls assigned to the Coll de Malla Formation (Lutetian) in the area of Vic (Barcelona) and Sarrià de Ter (Girona) have yielded several specimens of a new brachyuran that can be assigned with confidence to the superfamily Majoidea. General carapace shape, the produced and bilobed front, with two longitudinal rounded ridges, the construction of the orbits, the gently arched posterior margin, as well as the strong conical protuberances in the dorsal regions, favour placement in the family Inachidae. The construction and distribution of the axial and branchial regions confirms assignment to the genus Planobranchia. Distinct features seen in the new material, such as the arched epibranchial ridges bounding the urogastric region, the gently arched posterior margin, and stronger protuberances in the dorsal regions permit the erection of a new species, Planobranchia palmuelleri. The excellent preservation of the anterior portion of the carapace in this new species adds to our knowledge of the genus, the diagnosis of which is emended.
