Etymology

The new species is named after the collector of the holotype, Prof. Dong Hui (Shenzhen City).

Remarks. The new species has no similar species in China, and is also easily separated from the Vietnamese species. Three species, namely A. axana Chen, 2020 , A. nobilitata Klapálek, 1909 and A. apicalis Stark and Sivec, 2008 , share dark wing tips ( Chen 2020), and three species, namely A. bachma Cao and Bae, 2007 , A. songhaitiani Chen, 2020 and A. taygianga Chen, 2020 , have in common a pair of aedeagal sclerites, whereas A. magnifica Cao and Bae, 2007 has a curved aedeagus.
