DISTRIBUTION

Collected in March, 2010 from Ahar Village , Tehran Province, Iran, in the rhizosphere of grasses.

REMARKS

The examined specimens fit very well with the recent redescription of this species by Guerrero et al. (2008a), although some observed morphometric differences are considered as intraspecific variation. The Iranian population has a slightly longer pharyngeal expansion (140-162 vs 111-142 µ m) and shorter female tail (19-24 vs 22-37 µ m; c = 73-104 vs 53-83; cļ = 0.4-0.6 vs 0.6-0.8). Moreover, taking into account the tripartite nature of the uterus in this species, as illustrated by Guerrero et al. (2008a), the Iranian population has a less developed pars distalis than Iberian populations, although the pars dilatata oviductus is more developed than in the Iberian specimens and female tail lacks saccate bodies (vs some very small bodies observed).

One of the four females observed had two vulvae. Its morphometrics are: L = 1.89 mm, a = 23.9, b = 5.1, c = 82, cļ = 0.5, V 1 = 34.0, V 2 = 41.5, lip region diam. = 22 µ m, odontostyle length = 45 µ m, odontophore length = 53 µ m, neck length = 372 µ m, pharyngeal expansion length = 155 µ m, anal body diam. = 45 µ m and tail length = 23 µ m.

This is the first report of the species in Iran.
