Figs 4 , 26–27 , 75.

DISTRIBUTION. South-eastern Transbaikalia, southern part of the Russian Far East, Eastern Mongolia ( Fig. 4 ).

HOST. Was found only on S. schwerinii , often dwells together with M. regalis .

11. Macropsis cerea (Germar, 1837)

Figs 3 , 33–37 , 83–92.

Macropsis fieberi Ossiannilsson, 1938: 76 [synonymy by Tishechkin, 1998].

Macropsis kaahemica Vilbaste, 1980: 26–27 , s yn. n.

DISTRIBUTION. Transpalaearctic within the forest zone; known from several localities in Northern Mongolia ( Fig. 3 ).

HOST. On different willow species.

REMARKS. Was recorded from Mongolia by Dlabola [1965, 1967b, d].

M. kaahemica was described based on a single male with body length (including forewings) 4.70 mm from Kaa- Khem near Kyzyl, Tyva, Southern Siberia. The translation of the original description from Vilbaste [1980] is given below.

“Almost monochrome, light brown. Front part of body monochrome, only lateral part of pronotum, which is greatly expanding downward, whitish yellow, with large black-brown spot. Same, but lighter spot presents on rather sharp episternum of prothorax.

Scutellum with slightly more brownish basal triangles. Transverse scar very narrowly bordered by brown. Forewings more intense brown, very shiny, sometimes with whitish coating. Veins of same colour, only marginal vein (except apical margin) whitish.”

In the course of our studies in Southern Siberia, including Tyva, we found only two species with brown coloration which fit this description, M. cerea ( Figs 33–37 ) and M. flavida Vilbaste, 1980 ( Figs 38–45 ). In both species, the dark pattern is very variable, so finding the specimen that matches the above description quite accurately is not difficult; among the specimens in the photographs these are males on Fig. 34 and, to a lesser extent, on Fig. 33 .

According to our measurements of specimens from Mongolia, the body length (including forewings) of M. cerea males is 4.7–5.0 mm, 4.82±0.094, n=15 (range, mean ± standard deviation, number of specimens measured), whereas in M. flavida it is 3.9–4.6 mm, 4.32±0.169, n=30. Thus, in the body length M. kaahemica falls into the variation range of M. cerea .

In M. cerea , penis in side view on average is wider than in M. flavida (cf. Figs 86–90 and 96–100). In this trait M. kaahemica (Fig. 91) also falls into the variation range of M. cerea . For this reason we establish a synonymy M. cerea (Germar, 1837) = M. kaahemica Vilbaste, 1980 , syn. n.

It should be added, that M. cerea also differs from M. flavida in the shape of male 2 nd tergal apodemes (cf. Figs 83– 85 and 93–95), in a number of subapical teeth on 2 nd valvulae of ovipositor (cf. Figs 92 and 101–102), and in male calling signal pattern, but these traits are not mentioned in the original description.
