PARATYLENCHUS TENUICAUDATUS N. SP. (NEMATODA: CRICONEMATIDAE)

Abstract

Paratylenchus tenuicaudatus n. sp. was collected in Ontario, Canada, from soil about roots of clover (Trifolium repens and T. pratense), of alfalfa (Medicago sativa), of maple tree (Acer saccharum), and from grass sod, during 1958 to 1960.This species has characters close to Paratylenchus hamatus, P. elachistus, and P. nanus, but differs from these species in having a long slender tail, in having the vulva in a more forward position, in having a more massive basal bulb of the esophagus, and in the fact that it is a considerably larger species.
