IX. 2008 , Tingting Zhang. Distribution. China (Beijing, Hebei, Ningxia, Yunnan). Etymology. The species epithet derives from the Latin “ aquila ” [= dark-colored]; referring to infuscation on the anterior part of the wing. Remarks. The new species is similar to V. fasciata (Meigen) , but it can be separated from the latter by tergite 4 with white recumbent scales anteriorly and tergites 1, 5, and 6 with white recumbent scales posteriorly. In V. fasciata , tergites 2–3 have yellowish recumbent scales antero-laterally, tergite 4 has yellowish recumbent scales anteriorly, and tergites 5–6 have yellowish recumbent scales posteriorly.
