Mandibles bidentate, the second tooth short and bluntly rounded, their base strongly punctured, the lower 

 half more closely than the upper. Metanotum opaque, coarsely alutaceous. Legs covered with white hair; the 

 calcaria rufo-testaceous, the fore tibiae on the upper side at the apex slightly projecting; the coxae not spined.

? is similar, clypeus is fringed with long rufous hair, scopa white, tinged slightly with rufous. 



This species is very similar to M. prionsa; the latter is a narrower, more elongated species, especially 

 as regards the abdomen, which is clearly longer than the head and thorax united, scutellum is more broadly 

 rounded and it wants the stout lateral spines, head is longer, especially behind the eyes, and the 2. tooth of the 

 mandibles is biunter, more broadly rounded.
