DIAGNOSIS. Among aphid species living on Achillea millefolium ( Blackman

& Eastop, 2021), the new species is most similar to European M. silvestrii Roberti,

1954 ( Roberti, 1954; Barbagallo, 1969). Macrosiphoniella kazakhstanica sp. n.

differs from latter species in the number of secondary rhinaria in apterous and alate viviparous females (5–10 and 24–26 vs 14–25 and 48–68), the ratios of processus terminalis to the base of antennal segment VI (3.7–4.9 vs 2.8–3.6), length of antennal segment III to processus terminalis (0.82–0.98 vs 1.11–1.36), absence of dorsal sclerites at base of setae, and color of all tibiae (brown in M. silvestrii and pale in the middle in M. kazakhstanica sp. n.).

HABITAT. Aphids live on the underside of the ground leaves of Achillea millefolium L., Handelia trichophylla (Schrenk) Heimerl (Asteraceae) the in scattered colonies. Only alate and apterous viviparous females have been found.

DISTRIBUTION. Central, South, and South-East Kazakhstan.

ETYMOLOGY. The species is named after the country where it was collected.
