St. Wiistneii ist dem limpidipennis zum Verwechseln ähnlich; 

 allein limpidipennis hat einen Hinterleibstiel, der sichtlich kürzer 

 als der übrige Hinterleibstheil, während er bei Wiistneii ebenso laug 

 ist, das Mittelsegment ist mehr zerstreut punktirt bei limpidipennis 

 und der Hinterleibstiel grober und deutlich- quergerunzelt.
