The type of the name banchiformis Megerle is lost. The original 

 description is "ex Georg. Stat. Banch. Atr. fiav. vari. ant. annul. 

 Thor. 2 spinos." While brief and abbreviated, Megerle's description 

 is of a species from Georgia, of the size and shape of Banchus, black 

 with yellowish marldngs (including a white band on the flagellum), 

 and the propodeum with evident teeth. This description fits the male 

 of the present species perfectly, and while it could possibly have been 

 based on some other species, it has seemed better to apply the name 

 definitely, using the right of the first reviser, than to let it remain 

 a nomen duhium.
