Females do not agree with those of  N. bergevini orientalisZettel, 1996, described from Iraq. The easternmost species  N. signatusDistant, 1910, recorded from Indiato Vietnam, also exhibits features distinct from specimens collected here (see e.g., Distant 1910b; Polhemus & Polhemus 1994, 2000; Thirumalai 2002; Chandra et al.2012). The status of the genus and, especially of the subspecies of  N. bergevini Bergroth, 1911as currently interpreted (see Polhemus & Polhemus 1994), is far from satisfactory and needs a taxonomic revision. In particular, in part because of the records reported here, the subspecific status of  N. bergevini popoviis difficult to justify since another subspecies (  N. bergevini orientalisfrom Iraq) lies interposed between the populations of  N. bergevini popovifrom the Near East (see Andersen 1995) and those from Pakistan. No records of this genus exist for Iran(see Ghahari 2013, Ghahari et al.2013). The taxon was originally described as  Naboandelus popoviby Brown (1951: 227)and subsequently downgraded to a subspecies of  N. bergeviniby Linnavuori (1975: 46). However, this taxon should probably be synonymized under  N. bergevinior deserve specific level status.
