Abstract
Laimaphelenchus are very small nematodes, some parts of their body are measured in nanometers. In the past, the only way of identification and classification of these organisms were morphology based on anatomy and measurements. Nowadays, this approach is ap­pended with nano-morphology with the help of scanning electron microscopy which reveal unknown morphological details facilitating the taxonomy work. A new species of the genus Laimaphelenchus is recently described. Laimaphelenchus belgradiensis is discovered on a black pine showing symptoms similar to those caused by Bursaphelenchus xylophilus. Although both species belong to the same family and are similar in morphological sense, females of both species have the vulval flap and males have similar spicules, they possess significant differences. The main morphological difference is the presence of supplementary tail organs-tubercles with finger-like protrusions, visible only with scanning electron microscope. The role of the protrusions is explained and a key to species of the genus Laimaphelenchus is given in this paper.
