Etymology

Etymology. The species is named for the yellowish hairs on the thorax.

Discussion

Remarks. The new species is similar to V. fasciata (Meigen), but it can be separated from the latter by tergites 2–4 with white recumbent scales antero-laterally and tergites 5–6 with white recumbent scales postero-laterally. In V. fasciata, tergites 2 and 3 have yellowish recumbent scales antero-laterally, tergite 4 has yellowish recumbent scales anteriorly, and tergites 5–6 have yellowish recumbent scales posteriorly.
