Eosalpingogaster and Salpingogaster are readily distinguished from all other syrphine groups by the presence of distinct black spinose bristles on the metafemur combined with the petiolate abdomen and sinuate vein R4+5. Both genera have petiolate abdomens, but Salpingogaster is distinguished from Eosalpingogaster by the much more greatly sinuate vein R4+5; other syrphines with sinuate vein R4+5 have oval abdomens. Eosalpingogaster has 1st tergum not produced into a spur, vein R4+5 only slightly sinuate and occipital cilia in 3–4 rows dorsally. In contrast, Salpingogaster has 1st tergum produced laterally into a strong spur and occipital cilia reduced to a single row dorsally.
E. conopida is only known from the Andean region, and it is very distinct with no yellow maculae on pleuron. E. conopida has black abdomen with 3rd abdominal tergum with two basolateral yellow maculae that can join medially forming a broad fascia. Similar to E. cochenillivora but conopida has the pleura entirely dark brown.
