Types
Holotype: Apterous viviparous female (specimen 1), on Dianthus sp. Kalam (Khyber Pakhtunkhwa), Pakistan, 1800 m, 17-VIII-1991, Naumann-Etienne leg. [Remaudière’s sample 014072]. Paratypes: 3 apterous viviparous females with the same data that the holotype.
Etymology
The specific name of the new species is an adjective that refers to Pakistan, in feminine.
Discussion
Aphidura pakistanensis sp. n. is the third species of the genus living on Dianthus. Its distinctive features are summarized in the identification key to apterae of Aphidura in the general discussion, and in the following modification to the key to aphids on Dianthus (Blackman and Eastop 2006[1]) for addition of Aphidura pakistanensis:
