Morphometrics of three putative species of the Xiphinema americanum group (Nematoda: Dorylaimida) from the territory of the former Yugoslavia

L. Barsi, F. Lamberti


Two females of Xiphinema incertum from Serbia and populations of X. pachtaicum from Macedonia, Montenegro and Serbia and X. simile from Serbia are briefly described. Morphometries and illustrations of female and juvenile stages are provided. Males of X. sirnile are also reported. It is hypothesized that X. incertum represents aberrant females of X. pachtaicum. X. pachtaicum from Macedonia has four juvenile stages, but X. simile from Serbia unequivocally has only three.
