Head setae 0.025–0.045 mm long. HW 0.52–0.65 times ANT. ANT (Fig. 6 b) 0.35–0.53 times BL. ANT III shorter or longer than ANT VI, 0.10–0.15 times BL. ANT IV 1.13–1.71 times ANT V. ANT V 0.92–1.25 times BASE. ANT VI with PT 1.46–2.12 times BASE, with rounded primary rhinarium and 3–4 small accessory rhinaria tightly adjoining each other directly to the major rhinarium (Fig. 6 c). Other antennal ratios: ANT VI:ANT III 0.84–1.06; ANT V:ANT III 0.31–0.40; ANT IV:ANT III 0.42–0.54. Antennal chaetotaxy: ANT I with 5–7 setae, ANT II with 4–5 setae, ANT III with 5–11 setae, ANT IV with 3–7 setae, ANT V with 2–4 setae; ANT VI with 4 basal, 4 apical and 1–2 setae on basal part of PT. Antennal setae short, 0.008–0.020 mm long and pointed; LS ANT III 0.75–0.90 times BD III. Rostrum, reaching from middle coxae to ABD V. ARS 0.77–1.06 times ANT III, 2.26–3.00 times BASE, 0.89–1.02 times ANT VI and 1.61–1.90 times HT II, with 2–3 accessory setae (Fig. 7 a).
Thorax with short to medium rigid, spindle–shaped setae, on pronotum 0.017–0.035 mm long and placed antero-marginally and spinally, 0.012–0.042 mm long on mesonotum and 0.015–0.031 mm long on metanotum. Mesothoracic furca transparent, separated; metathoracic furca short, weakly developed. III FEMORA 0.19–0.26 times BL, III TIBIAE 0.32–0.45 times BL, posterior seta on hind trochanter 0.53–0.69 times diameter of trochantro-femoral suture. HT II 2.62–3.51 times HT I. First segments of tarsi with 3:3:3 ventral setae (Fig. 7 b). HT II 0.44–0.57 times ANT III, 1.26–1.64 times BASE and 0.48–0.56 times ANT VI. Empodial setae fine and pointed. ABD I–VIII covered by short or medium rigid and blunt setae in spinal, pleural and marginal positions, 10–16 setae 0.017–0.042 mm long on ABD I–V, 6–10 setae 0.020–0.075 mm long on ABD VI–VII and 6 (rarely 5) setae 0.047 –0.075 mm long on ABD VIII. Dorsal setae on ABD III 1.0 4–1.35 times BD III. Dorsal surface of ABD segments in form of polygons with irregular edges. ABD I–IV membranous, ABD V with spinal or spino– pleural scleroites and sclerites. Sclerotic cross–bars of ABD VI–VIII imbricated or covered by very short spinules. SIPH (Fig. 7 c) 1.36–1.86 times CAUDA, 0.06–0.08 times BL and 0.52–0.65 times ANT III, slightly imbricated with poorly developed flange and subapical constriction. Subgenital plate well developed with 2 anterior and 12– 18 posterior fine and pointed setae. Cauda with 5 fine and pointed setae (Fig. 7 d).
Etymology. 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).
