Aneurus pygmaeus, new species, is related to A. minutus Bergroth, 

 from which it differs by the following: scutellum regularly semi- 

 circular, in A. minutus more narrowed at the tip, almost subtriangular; 

 paratergites of male larger, and widened toward the tip, in A. minutus 

 narrower, almost subcylindrical; whitish semi transparent membrane, 

 in A. minutus bro\\"n and not transparent; dark ferruginous body, 

 in A. minutus yellow brown (I hold the former color as distinctive) ; 

 in the female, abdomen narrow and long, in A. minutus more ovate; 

 paratergites are also different.
