Epistrophella emarginata (Say)
Say (1823) described Scaeva emarginata from Florida. Dusek and Laska (1967) created a new genus for Syrphus euchromus Kowarz, 1885, Epistrophella and included emarginata. Vockeroth (1969) indicated the unusual variation in thoracic and abdominal markings of Epistrophe and suggested to use the two subgenera: Epistrophe s.s. and Epistrophella.
The analyses of larval morphology guided Rotheray and Gilbert to synonymize Epistrophella under Meligramma. Results from Mengual et al. (2008) suggested that Epistrophella is close to Xanthogramma, in agreement with larval evidence (Rotheray and Gilbert, 1999), close to the clade of
Epistrophe but placed separately.
