The authors have the pleasure to name the species to honor Prof. Abdusalom Hafizovich Kadyrov—Entomologist from the Faculty of Biology, Tajik State National University in Dushanbe and long–term friend of the Department of Zoology, University of Silesia. Diagnosis. The new species differs from most of other species of Dysaphis by lack of marginal and spinal tubercles. Due to this character and slender and elongated ARS, the new species is similar to D. pseudomolli and D. cousiniae from which it differs by the following characters: Antennal setae long, LS ANT III 0.75–0.90 times BD III, while in D. (D.) pseudomolli LS ANT III are no longer than 0.5 times BD III. Setae on ABD I–V 0.017–0.042 mm, while in D. (D.) pseudomolli they are 0.04–0.06 mm long. 4 setae on the apex of PT, among which 3 are apical whereas in D. (D.) pseudomolli there are only 3 setae, with 2 apical. There are 6 setae on ABD VIII while in D. (D.) pseudomolli there are 4. Marginal tubercles always absent while in D. (D.) pseudomolli they are small and only rarely absent. From D. (D.) cousiniae cousiniae it differs by: Lack of sclerotized abdominal shield on ABD I–V. Lack of marginal and spinal tubercles on all body segments. From D. (D.) cousiniae minor it differs by: Lack of marginal tubercles on all abdominal tergites Slender, stiletto shaped apical segment of rostrum Host plant and biology: The species is associated with Anacantha darwasica (C. Winkl.) Soják (syn.: Modestia Char. & Tamamsch.) (Fig. 3). The host plant is endemic to the Pamiroalai Mountains in Tajikistan (Gissarskij Chrebet, Darvaskij Chrebet, Karategin, approx. 38°N, 68–73°E). Habitat: Subalpine meadows, screes and gravel embankments of rivers between 1300 and 3200 m (Fig. 8) (Soják 1982; Häffner 2000). The aphids were feeding on upper sides of leaves and on upper shoots near inflorescence and were attended by ants from the genus Plagiolepis Mayr, 1861 (Formicinae), det. Ł. Depa (after key to subfamilies and genera in Hölldobler & Wilson 1990). Locality. 38°51'52.7"N, 70°01'32.3"E; valley of the Vakhsh River, Central Tajikistan province, Sarikhosorsubdarvaz region; 1160 m asl; dried river bed, overgrown by sparse herbaceous vegetation (Fig. 8).
