M. pompilina Malaise, 1945

Antenna entirely black, antennomere 3 approximately 1.4 times as long as antennomere 4; posterior margin of metepimeron extended downward, strongly concave, appendage wide and large; hind femur entirely black. China (Gansu, Shanxi, Henan, Hubei, Sichuan, Yunnan) ......................................................................................................................... M. parapompilina Wei & Nie, 1999

4. Hind tibia largely with reddish brown maculae at base, apex black, but without yellow macula ( Fig. 1 ); postocellar area 2.0 times broader than long ( Fig. 2 ); cell 2Rs as long as cell 1Rs, petiole of anal cell in the fore wing about 1.8 times longer than crossvein 1r-m and about 1.2 times longer than crossvein cu-a ( Fig. 1 ); middle serrulae of lancet in female each with 2 proximal and 9–11 distal teeth, not protruding mastoid-like ( Fig. 8 ). China (Shaanxi, Hubei) .................................................... M. brevicinctata sp. nov.

Hind tibia largely black, middle part with distinct yellow ring, usually color ranged from yellowish white to yellow, but without reddish brown macula absolutely; other characters not different from the former ...............................................................................5

5. Pronotum entirely black in female; lateral corners of posterial margin with clear yellowish white maculae in male; middle part of hind tibia with yellowish white ring in two sex specimen, shorter than 1/2 times of hind tibia clearly ............................................... 6

Lateral corners of posterial margin of pronotum with yellow maculae distinctly in female; unknown in male; hind tibia with yellow ring from subbasal to middle parts, not shorter than 1/2 times of hind tibia ........................................................................................ 7

6. Postocellar area about 2.5 times broader than long; hind tarsomere 1 entirely black. North Korea; Japan, East Siberia, China (Heilongjiang, Jilin, Liaoning, Gansu, Henan, Sichuan) ...................................................................... M. annulitibia Takeuchi, 1933

7. Mesoscutellum entirely yellow; posterior margin of metepimeron clearly extended downward and concave, appendage long and narrow, containing some minute punctures; fore coxa largely yellow, with small black maculae; basal half of middle femur yellow, apical half black; basal 4/7 of hind femur yellow, apical 3/7 black; hind tarsus largely yellow, base of hind tarsomere 1 black; apical 1/7 of fore wing with a subrounded, smoky macula. China (Tibet, Sichuan)................................................ M. xinan Li & Liu, 2015

Mesoscutellum entirely black; posterior margin of metepimeron extended downward and concave, appendage broad, containing some large punctures; fore coxa largely black, with small yellow maculae; basal 1/3 of middle and hind femora yellow, apical 2/3 black; hind tarsus entirely yellow; fore wing without smoky macula.
