Pristina multiseta sp. nov. is described from rice paddies in Japan. This species resembles P. aequiseta Bourne, 1891 and P. evelinae Marcus, 1943 in having proboscis and shortly bifid distal ends of dorsal needles, however P. multiseta is distinguished from these species by the short proboscis, a higher number of chaetae in dorsal bundles, and enlarged ventral chaetae from IV through VII. Thin vessels surrounding the ectal half of the atria in this species are unique in the genus.
