Tetranychus arabicus Attiah, the valid name for the green two spotted spider mite in Egypt (Acari, Tetranychidae)
1993 - Volume: 34 Issue: 1 pages: 47-50
Tetranychus arabicus Attiah is the valid name for the common green spider mite in Egypt, oppposing some recent workers giving it the name T. urticae Koch. Aedeagal knob of the latter s male is very small not over one-sixth as long as the dorsal margin of shaft, whereas T. arabicus falls in the group whose knob is comparatively large, about 1:3-1:4 as long as the dorsal margin of shaft. T. cinnabarinus (Boisduval), T. cucurbitacearum (Sayed) and T. arabicus are all valid species different from T. urticae, contrary to a late publication issued in South Africa.
