about its role as a plant pathogen and it has not been recorded as a vector of plant viruses. Mojtahedi et al. (1980) reported X. pachtaicum for the first time from vineyards in Iran; later on, it was obtained from different localities in the country from the rhizosphere of different plants. The Iranian specimens fit, morphologically and morphometrically, well to earlier descriptions of the species ( Fadaei et al., 2003; Getaneh et al., 2015; Lazarova et al., 2016).
