Eupeodes (Macrosyrphus) horishanus (Matsumura, 1917).
Matsumura, S. and Adachi, J. (1917) Synopsis of the economic Syrphidae of Japan. (Pt III). Entomological Magazine Kyoto 3, 14-46.
In Rotheray and Gilbert (1989), Eupeodes was placed as sister group of Scaeva. In 1999, results by Rotheray and Gilbert using larval morphological characters resolved Eupeodes as siter group of Scaeva and Ischiodon.
Mengual et al. (2008) studied the subgenera Eupeodes (Macrosyrphus) and Eupeodes (Metasyrphus) and results supported Macrosyrphus as sister group of Metasyrphus. The previously considered subgenus Lapposyrphus was placed as a separate genus, resolved in the same clade as Eupeodes, but closer to Pseudodoros + Simosyrphus + Scaeva.
