Four new saproxylic species of the genus Paranura from Nagasaki, Nara, and Niigata provinces of Japan are described and illustrated in this paper. Paranura tsushimaensis sp. nov. is characterized by a dark blue body color, Abd. V four times as long as Abd. VI, 3+3 eyes, three ocular chaetae on the head, four ordinary chaetae De on Th. III, two ordinary chaetae Di on Abd. V, and all dorsal chaetae of Abd. VI in a unique reticulated plate. P. nakamurai sp. nov. is identified by its yellowish white body color, 2+2 eyes, tubercle Af on the head with two reticulated tubercles, and tubercles Di on Abd. V fused. P. alpicola sp. nov. is characterized by its yellow body color, 3+3 eyes, presence of complete chaetotaxy in the central area of the head, Th. II–III with two and three ordinary chaetae De respectively, and tubercles Di on Abd. V separate. P. convallis sp. nov. is identified by its orange body color, 3+3 eyes, head without chaeta O, three mandibular teeth, and Th. II–III with three and four ordinary chaetae De respectively. A key for all species of the genus Paranura is provided.
