REMARKS. According to Kerzhner (1972), P.K. Kozlov collected in those days in

South-Gobi aimak [Ömnögovi Prov.] on the south slope of Mt. Dund Saikhany Nuruu

(middle mountain of the Gurvan Saikhan Mountains). Kozlov spent those days in a camp at some “red” hills (Kozlov, 2015). Thus, the type locality of C. kozlovi was located at approximately 43°33′N 103°43′E (the rightmost point on Fig. 5 ), where a relatively large area of red-colored ground is visible via Google Earth (https://www.google.com/earth/).

Males of this species are still unknown.

BIONOMICS. In the field C. kozlovi was observed in the Tydtuyaryk River valley only

( Fig. 6 ); it was absent from the Chuya River valley. Females of this species visited flowers of five plant species of the families Lamiaceae and Asteraceae ( Table 1). The only pollen source, however, was flowers of Dracocephalum peregrinum . During pollen uptake from these flowers, females stood on the lower lip of the corolla and consumed pollen directly from the anthers. They did this with their mouthparts supported by movements of the fore legs; mid and hind legs were used to hold onto the corolla ( Fig. 7 ). The duration of pollen collecting per flower was approximately 40–45 sec. After that, females went deeply inside the corolla to take up nectar. During nectar collecting they were not visible from outside due to the deep and broad corolla tube which completely hid the wasps. The duration of nectar collecting was significantly less (about 5 sec.) than that of pollen collecting.

Only nectar collecting was observed at flowers of Ziziphora clinopodioides . Flowers of this species are significantly smaller than those of D. peregrinum ; the corolla tube is even shorter than the proboscis of the wasp. Thus, during flower visits females alighted on the lower lip, hold onto it with all their legs and simply inserted the proboscis into the flower

( Fig. 8 ). Duration of nectar collecting on Z. clinopodioides was also about 5 sec. One female was observed to collect earth after visiting several flowers of Z. clinopodioides . She did this on a slope with quite loose ground between plants of this species.

It must be specified that there were no plants of Dracocephalum nutans in the

Tydtuyaryk River valley. Other species of Lamiaceae were represented in this habitat by

Panzerina canescens (Bunge) Soják and P. lanata (L.) Soják, but they were not visited by

C. kozlovi .

Visiting plants of the family Asteraceae , females landed directly on the center of the capitulum and inserted the proboscis into one of the florets for a very short time. Then, they flew away in all three observed cases.

First activity of the wasps was recorded in the morning at 9.35 (solar time). In the late afternoon, the activity finished at various times depending on the weather.

No males of C. kozlovi were observed despite thorough searching.
