Members of Salpingogaster can be distinguished from other Syrphini by the combination of an elongated, somewhat constricted and characteristic patterns typical of the tribe. -level identification requires examination of male and facial . The superficially resembles some Bacchini but lacks the distinctive facial found in that tribe.
