Eosphaerophoria symmetrica Mengual  

Species with notopleuron not produced posteroalterally and a yellow macula on 2nd abdominal tergum. Similar to E. punctata, but differs in having the frons yellow on ventral 4/5 and 1st abdominal tergum yellow with 2 posterior subtriangular black maculae.

This species is very similar to E. punctata. Both species share a unique morphological character with E. bifida: a medial yellow macula on 2nd abdominal tergum. Eosphaerophoria symmetrica could be the male of E. punctata because they also have in common the absence of the posterolateral obtuse protuberance of notopleuron, but they differ in the abdominal pattern of the 1st tergum and the frons. Nonetheless, due to the low number of records/specimens of this genus and the morphological differences, we consider E. symmetrica as a species different from E. punctata. Eosphaerophoria symmetrica and E. vietnamensis are described from the same locality, but they present several differences that make them easy to distinguish: E. symmetrica has a yellow macula on 1st abdominal tergum, and a yellow fascia on 5th tergum. Eosphaerophoria vietnamesis has 2nd tergum black with yellow lateral margin and two yellow maculae on 5th tergum. Moreover, the superior lobes of the male genitalia in E. vietnamensis are asymmetrical, unlike E. symmetrica which has them symmetrical.
