Aphids associated with Lamiaceae in Iran with redescription of Ovatus mentharius (van der Goot, 1913) (Hemiptera: Aphididae)

Abstract

There are 33 aphid species reported so far on Lamiaceae plants in Iran. In this research, a total of 19 aphid species belonging to 12 genera were collected on 20 host plant species. Furthermore, 33 associations between aphid species and host plants were recognized, of which six are new for Iran. Among the examined specimens, an Ovatus species collected on Mentha longifolia showed a complete range of intermediate biometric data of O. mentharius (van der Goot, 1913) and O. archangelskajae Kadyrbekov, 2008. In view of the biometric data from samples of Iran, we conclude that O. archangelskajae is a geographical variant of O. mentharius, therefore we consider it as a synonym for O. mentharius and redescribe O. mentharius as its morphological entities are extended. In this paper, the distribution of the aphid species in different parts of Iran is also presented and six new occurrences are reported for Fars and Kerman provinces. An identification key to the apterous viviparous female aphids living on Lamiaceae in Iran is provided.
