Pratylenchus jaehni identified according to genus Pratylenchus key. (Castillo and Vovlas, 2007) It is close to P. coffeae and P. loosi. It differs from P. coffeae and P. loosi by only a few morphological characters of the females. The mean values of stylet length, stylet knob height and vulva position are smaller than those in P. coffeae and P. loosi, respectively. P. jaehni overlap the low range values of P. coffeae and P. loosi. No morphological differences were observed among P. jaehni males and those of P. coffeae and P. loosi. The tail terminus was usually subhemispherical and smooth in P. jaehni, whereas it was commonly truncate and indented in the standard populations of P. coffeae and bluntly or finely pointed in P. loosi.
