During the study of aphid fauna of Kerman province, Iran, an aphid species, Chaetosiphella longirostris Wieczorek, ۲۰۰۸ (Hem.: Aphididae: Chaitophorinae), was collected on Stipa arabica Trin. & Rupr. (Poaceae), which is reported here for the first time from Iran. This is the second aphid species reported on Stipa in Iran. Since there were some morphological differences between the original description of C. longirostris and Iranian population, here we made a diagnostic comparison. The biometric data of the Iranian population of C. longirostris is given and compared with the original description.
