Abstract
Two new species of Pratylenchus from forest soil in Japan are described and illustrated. P. yamagutii n. sp. from Mt. Eniwa, Hokkaido is characterized by two head annuli, rounded spermatheca, and presence of males. This new species is similar to P. coffeae, P. alleni and P. neglectus, but differs from the first species in the shorter body, smaller b-value and dumbbell shaped submedian face segment; from the second in the longer stylet, rounded to oval spermatheca and slender tail; and from the third in the presence of males, more tail annuli and anterior location of phasmids in tail. P. okinawaensis n. sp. from Kunigami, Okinawa has two head annuli, crenate tail terminus and oblong spermatheca. This new species resembles P. flakkensis in the shape of the tail terminus, but can be separated from the latter by the oblong spermatheca and larger V-value. Jpn. J. Nematol. 21: 18-25 (1991).
