The genus
This study aims to investigate the taxonomic status of the genera
The specimens were examined and dissected under a Nikon SMZ800 microscope, and photographs were taken using Canon EOS 5DSR camera and processed by Adobe Photoshop 2021. The distribution map was made by QGIS and processed by Adobe Photoshop 2021. Aedeagi was detached from the body with insect pins, then glued to separate cards and pinned under the specimens. A single slash (/) separates data of different lines on a label, a double slash (//) separates data of different labels, authors’ remarks are enclosed in brackets “ []”.
Specimens examined in this study are deposited at the following institutes and collections:

This new species is obviously different from other species in the following characters (based on male): body large size, length 15.5–17.5 mm (vs. 11.1–13.8 mm in other species); inner side of metatibiae with a row of well-developed densely hairy brush from middle to apex; ventral surface of pro- and mesotarsomeres I–IV, and metatarsomeres I–III with well-developed hairy brush from middle to apex; parameres laminar in dorsal view.
