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. cochenillivora is a very common species with pleuron reddish brown with anepisternum yellow on posterior 1/3 and katepisternum with a dorsal large yellow macula; scutum black medially with a narrow, sometime indistinct, medial pollinose vitta; abdomen black except 1st tergum yellow basolaterally, 2nd tergum black, 3rd tergum with a basal broad yellow fascia and a narrow yellow fascia on posterior margin, 4th tergum black with a narrow yellow fascia on posterior margin. Eosalpingogaster cochenillivora is similar to E. nigriventris, but the last has 4th tergum with two basolateral triangular yellow maculae and scutum with a medial broad pollinose vitta. Male genitalia are also different.
