Vertex, temples and occiput smooth except for micropunctures. Ocelli small, OD:APOL:POL:OOL=2:2:4:5. Antennae as wide as body, penultimate joint of antennae 2.8 times as long as wide. Mesosoma as wide as head, ratio of its length, width and height as 42:25:30.Mesoscutum mostly smooth except for micropunctures in anterior and lateral part. Notauli slightly indented, smooth. The area where notauli meet posteriorly a little depression with some micropunctures. Dorsal scutellum evenly punctate. Stigma 3.1 times as long as wide,1 R 1 as long as stigma, r: width of stigma: 2 SR=6:7:6, areolet quadrangle, 1 CU 1 0.4 time as long as 2 CU 1. T 1 subparallel, narrowing in posterior 1/3, 2.1 times as long as the greatest width, smooth in basal 2/3, and rugulose in apical 1/3, apical margin with small smooth swelling. T 2 as long as T 3, smooth with a shield shaped median field indicated by oblique groove. Body black; palpi pale yellow; mesosoma black but tegula reddish yellow; hind coax black only apically reddish yellow, fore and mid legs including coax reddish yellow, hind leg reddish yellow but basal, apical tibia and tarsus dark; metasoma black, laterotergites of T 1 T 3 reddish yellow.

This species closely related to M. hyalipennis Alexeev, but differs from the latter by the combination of the following features: 1) head in dorsal view behind eye not broading; 2) antenna dull reddish yellow; 3)1 R 1 as long as the length of stigma; 4) T 2 with a distinct medial field indicated by oblique groove.
