MEASUREMENT OF ALLOTYPE. Body 2.99; antennae 3.34–?: III 0.79–0.83,

HOST PLANT. Artemisia (Oligosporus) arenaria DC. , A. (O.) scoparia Waldst.

et Kit., A. (O.) tomentella Trautv. (Asteraceae) .

BIONOMY. Aphids live on the stems to the flowers.

DIAGNOSIS. The new subspecies is basically similar to the nominative. M.

scopariae deserticola Kadyrbekov, ssp. n. differs from M. scopariae scopariae

Bozhko, 1959 by the absence of antesiphuncular and other sclerites on the abdomen in all seasonal morphs, lighter coloring of the head, antennae and legs in wingless viviparous females, somewhat lower ratio of siphunculi to body length in apterous viviparous females (0.20–0.22 against 0.23–0.25) and, on average, somewhat more hairs on the cauda (12–15 compared to 10–11).

DISTRIBUTION. Sandy deserts of South Kazakhstan.
