( Fig. 2 , Table 1 ) Type material . Holotype : apterous viviparous female, slide no 5041, South Kazakhstan , West Tien Shan , Sairam-Ugam natural park, Karzhantau gorge, Kyrykkyz pass, H- 1861 m a.s.l. , Stachys betonicifolia , 9.08.2014 , R . Kadyrbekov ( Institute of Zoology , Almaty , Kazakhstan ). Paratypes—9 apterous viviparous females, same place and date ( Institute of Zoology , Almaty , Kazakhstan ). Etymology. The new species is named after Karzhantau gorge, where it was collected. Apterous viviparous female (from 10 specimens ; for measurement see Table 1 ). In life: body white with green markings, eyes are reddish. On slide: body and appendages pale without dark parts. Body is elliptic (fig. 2 a). Frontal groove is middle deep. Its depth 0.18–0.25 of the distance between bases of antennae. Antennal tubercles are distinct and divergent. Median frontal tubercle is well developed, quadrate (fig. 2 a). Cephalic hairs are long, with thick bases and capitate apices. Antennae are six-segmented; first segment has a large protuberance on inner side and bears 4 short hairs. Number of hairs on 2 nd– 6 th antennal segments are II—3–4, III—6–10, IV—5–6, V—4–5, VI—5–6. Basal parts of 3 rd and 4 th antennal segments with respectively 4–12 and 0–2 secondary rhinaria (fig. 2 b). Hairs on the 3 rd segment are short, slightly capitate. FIGURE 2.

Rostrum reaches beyond the bases of the hind coxae. Its ultimate rostral segment is wedge-shaped (fig 2 c) and bears 4–6 accessory hairs. Siphunculi are slightly swollen, with small distinct flanges (fig. 2 d). Cauda is blunt trian-gular or helmet-shaped (fig 2 f) and bears 5–7 hairs. Dorsal hairs on the 2 nd– 5 th abdominal tergites are capitate (fig. 2 e). Marginal tubercles are absent. Number of hairs on abdominal tergites: II–V—10–12, VIII—4–6. Genital plate is broadly oval, with 2–4 discal hairs and 10–11 posterior hairs. Legs are long (fig. 2 a). Hairs on the hind tibiae are slightly capitate, and 0.65–0.75 of its width at midlength. First tarsal segments with 3:3:3 setae.
Biology. This aphid lives on undersides of leaves of Betonica betonicifolia (Rupr., O. Fedtsch. et B. Fedtsch.) Sennikov (Lamiaceae) . It is not attended by ants. Other morphs and life cycle are unknown. Taxonomical notes . The new species together with C. ( Cryptomyzus ) taoi Hille Ris Lambers differs from all other species of the nominative subgenus by its relatively very long siphunculi (more than 5 times longer than cauda, whereas they are not more 4.5 times cauda in other species). Cryptomyzus ( Cryptomyzus ) karzhantavicus sp. n. differs from C. ( Cryptomyzus ) taoi in the ratios of 3 rd antennal segment to 6 th antennal segment (0.43–0.54 against 0.57–0.59), of processus terminalis to the base of 6 th antennal segment ( 5.8–8.2 in comparison with 9.0–9.1), of siphunculi to cauda length (5.1–6.5 versus 5.0–5.1), of siphunculi to the body length (0.30–0.35 as opposed to 0.20–0.25) and number of accessory hairs on the ultimate rostral segment (4–6 versus 7–9).
