ABSTRACT. Arcuphantes maritimus sp.n. is diagnosed and described from the Maritime Province, the Russian Far East. The new species can be distinguished from other species of the genus by peculiar shape of the paracymbium and the pseudolamella in males and by the expanded distal part of the scape in females. A revalidation of Fusciphantes Oi, 1960 and the establishment of Bifurcia Saaristo et al., 2006 are now recognized to be unsubstantiated because both were based on the symplesiomorphies. However, no nomenclatural changes are suggested due to the lack of type and comparative material for a detailed comparative analysis of these genera.
