Male. Holotype. Figs 56-64 . Measurements (mm): body length = 11.5.

Black, brown, pale yellow.

Brown: legs but X 1 and lighter portions; mandibles are light brown; hypostomal basis, veins, sul and ventral esdge of 7 th T are semitransparent brown.

Pale yellow: large subapical stripe and two very small spots along the keel on N 1 disk, most of tegulae, apical femurs, upper tibiae, all the tarsi; large (more than 1/3 the height of the element) apical stripe with straight foreprofile and enlarging at the sides on 2 nd to 6 th T, narrower with irregular foreprofile apical stripe on 1 st, 6 th T and 2 nd to 6 th sterna.

Secu stripe very narrow, about 1/8 the thickness of the elements; shallow notch between Tsa in dorsal aspect; clypeus with a very wide mid ventral projection which lacks mid ventral semitransparent border; N 1 disk strongly narrowing forwards, forming a sort of large collar, all its fore border with laminated keel and no prominent ventral tooth; postscutellar area well prominent about the propodeal surface; Em 2 distinct and completely wrinkled; Em 3 smooth and shining like the anteroventral lateral P; propodeal disk rounded without distinct horizontal and declivitous areas. No gradulus at the base of 7 th tergum.

p. denser on th lower frons; very sparse p. on vertex, genae, N 1, disk and basal half of T which have smooth apical half; more impressed sparse p. on 2 nd to 6 th sterna, denser throughout on 1 st sternum; detectable microreticulation on basal half sterna; the remain- der is like in M. tripunctata.

V a r i a b i l i t y:ThespecimenatMHNGhasabrownbasiccolourofthebody; some specimens are lacking for the small spots on anterior N 1 disk.

Female. Unknown.

D i s t r i b u t i o n: North Eastern areas of the Turanic Region.

D i s c u s s i o n: It shows the following good autapomorphies distinguishing it from the other taxa of the genus: the wide mid ventral projection of clypeal disk, the N 1 disk. narrowing in a sort of large collar, the large digitus of volsella and the absence of gradulus on 7 th tergum; the last one is hitherto not found elsewhere within the genus, while it is the standard in Poecilotiphia . The very narrow Secu stripe exists elsewhere only about M. lineata and M. cylindrica. Its general habitus looks like M. dorsalis but it differs from it also in the shape of the metasomal yellow stripes.
