This interesting species approaches Larra in the short 
tarsal ungues and sparse pubescence of the pygidial area, 
also in the characters of the head; but otherwise it has the 
characters of Notogonia, and is best placed in that genus.

Easily distinguished by the median segment, which is not 
margined laterally or apically, and has a median sulcus on 
the dorsal surface. The incision of the mandibles is much less 
distinct than in typical Notegonia, approaching Liris.

The median segment of this little species has the dorsal 
surface coarsely reticulate ; the third cubital cell is also much 
less produced on the cubitus than in most species of the 
genus. Allied to the Indian N. reticulata, Cam.
