Very similar to M. dodoneae Montr., but the 4th joint of the antennae is 

 much shorter than the 5th, instead of being of equal length, the eyes are larger 

 and more approximate, the distance between them in the being rather less 

 than that between the antennal bases, and the tibial combs are different 

 (Text-fig. 5).
