Morphologically close genera and how to distinguish them
Aglaoapis & Metadioxys species have a transverse carina on the labrum above the closed mandibles. Male genitalia are less than twice as long as width of the gonobase.
Paradioxys species have a clear carina between the lateral teeth of the scutellum . The tip of the female abdomen is needle-like due to an elongate and pointed sternite 6.
Ensliniana species have a rounded scutellum.
Stelis species have the second recurrent vein reaching at or beyond (apically) to the second submarginal cell.
Coelioxys species have 2 tooth-like axillae and a rounded scutellum. The tip of the abdomen is pointed in females.
