Remarks

It was collected from Iran, East-Azarbaijan province, Sufiyan, Roodghat area (GPS coordinates: N 38 o 22′ 10′′ E 46 o 07′ 26′′, altitude 1481 m a.s.l.), from the rhizosphere of common wheat (Triticum aestivum L.). This species is widely spread in Europe. Besides, it has been recorded from Asia, North America, South America and Australia. It inhabits vineyards and various orchards ( Andrássy, 2009). The original description of X. vuittenezi did not consider the presence of spines in the uteri and such structures were not mentioned in the revised polytomous key to the species of Xiphinema by Loof and Luc (1990), although distinct spindle-shaped structures of variable size and number were observed in the tubular portion of the uterus of an Iranian population of X. vuittenezi by Mojtahedi et al. (1980). For the first time in Iran, this species has been reported by Mojtahedi et al. (1980) from different regions of the country. The present Iranian specimens correspond well with the earlier descriptions in their general morphology and morphometrics as the relevant measurements and values are totally coincident or widely overlapping ( Luc et al., 1964; Barsi and Lamberti, 2000b; Kumari and Decraemer, 2006).
