Por no conocer la especie, que fué descubierta por Van Volxem, 

 transcribo la descripción dada por el autor citado : 



Allied to M. parmata, hut dijfering principally of the much narro- 

 iver and less target-like processes on each &ide by the pronotum, 

 which in this'species have more the appearance of broad lateral 

 brownish-ochraceous margins. The other characters are almost abso- 

 lutely identical with those ofM. parmata.. — Long. 3 mm.

 sigue:

 jointj anterior mar gin, a central longitudinal carina and a lar ge 

 target-like process on each side of pronotum, brownish-ochraceous.

 teous with fuscous transverse linear spots, membrane with an obscure 

 palé spotnear the apeoo. Body beneath dark fuscous, femora and tarsi
