Holotype : apterous viviparous female, slide No 5066, Kazakhstan : South Kazakhstan region , West Tien Shan , Karzhantau Range , Kyrykkyz pass, h~ 1861 m , on Pseudolinosyris grimii (Rgl. et Schrenk) Novopokr. , 11.VIII 2014, leg. R . Kh. Kadyrbekov. Paratypes : 21 apterous viviparous females together with holotype . DESCRIPTION. Apterous viviparous female (by 22 specimens ). Body oval, 2.29–2.88. Frontal groove is very deep with distinct antennal tubercles, 0.25–0.35 of the distance between bases of first antennal segments ( Fig. 1 ). Frontal hairs ( 0.050 –0.060 ) long, pointed, 1.3–1.5 of basal diameter of 3rd antennal segment. Antennae normal, six-segmented, 0.94–1.25 of body length. Third segment 1.25– 1.55 of 4th one, 0.80–0.95 of 6th segment, 1.05–1.25 of the processus terminalis ( Fig. 2 ). Processus terminalis 3.0–3.8 of the base of 6th segment. Secondary rhinaria in number 6–17 developed on the middle half of the 3rd segment ( Fig. 2 ). Hairs on the 3rd segment ( 0.030 –0.035 ) pointed, 0.75–0.85 of its basal diameter. Rostrum reaches before or behind of the hind coxae. Its ultimate rostral segment straight, not stiletto shaped ( Fig. 3 ) 0.8–0.9 of the second segment of hind tarsus, 0.60–0.77 of the base of 6th segment with 6 accessory hairs. Siphunculi cylindrical with not distinct flanges, 0.14–0.18 of body length, 0.9–1.0 of cauda length ( Fig. 4 ). Reticulated zone developed on the 0.25–0.35 of their length. Cauda finger-shaped with pointed apex, 2.3–2.9 of the second segment of hind tarsus with 10–17 hairs ( Fig. 5 ). Second segment of hind tarsus 0.80–0.95 of the base of 6th antennal segment. Dorsal hairs ( 0.050 –0.060 ) pointed 1.3–1.5 of the basal diameter of 3rd antennal segment. There are 10 hairs on 3rd tergite, 4 between siphunculi and 6–8 ones on the 8th tergite. Genital plate broad oval with 2 hairs on disk and 5―8 ones alon g its posterior margin. Legs normal developed. First tarsal segment with 3:3:3 hairs. COLOR ON SLIDE. Head, clypeus, ultimate rostral segment, 1st, 2nd, middle and apex of 3rd, apex of 4th, 5–6th antennal segments, anal and genital plates, sclerites in base of dorsal hairs on 6–8th tergites are pale-brownish; apices of femora, tibiae (occasionally with light brownish middle parts), tarsi, siphunculi (except of base) are dark brownish. Cauda is pale. Antesiphuncular sclerites are absent. Figs 1–5. Macrosiphoniella aizhanae Kadyrbekov , sp. n. , apterous viviparous female. 1 – head; 2 – third antennal segment; 3 – ultimate rostral segment; 4 – siphunculus; 5 – cauda. NATURAL COLORATION. Body is light green or light pink without slim, tibiae and siphunculi are dark brown. MEASUREMENTS ( holotype ). Body 2.42; antennae 2.73–2.75: III 0.74, IV 0.51, V 0.43–0.44, VI 0.81–0.83 (0.19+0.62–0.64); siphunculi 0.39–0.40; cauda 0.41; ultimate rostral segment 0.14; second segment of hind tarsus 0.17. HOST PLANT. Pseudolinosyris grimii (Rgl. et Schrenk) Novopokr. (Asteraceae) . BIONOMY. Aphids live on the stems of flowers. DIAGNOSIS. The new species belongs to the group of species that lack antesiphuncular sclerites. Among these species, by the depth of the frontal groove and the large size of the body, it is close to M. tapuskae (Hottes et Frison, 1931) . M. aizhanae Kadyrbekov sp. n. differs from this species by shorter siphunculi ratio to the body length (0.14–0.18 compared to 0.25–0.38) and cauda length (0.9–1.0 vs. 1.8–2.3) and the proportion of the processus terminalis to the base of the 6th antennal segment (3.0–3.8 and 4.2–5.3). DISTRIBUTION. Rock slopes of mountains. ETYMOLOGY. The species is named after my wife, an entomologist and con- stant companion in expeditions.
