Sichuan province is located in southwest China, covering an area of 48,000 square kilometers. The topography of Sichuan varies from mountains to basins, undulating with plateaus and hills. Usually, this region has typical subtropical monsoon climate. These patterns together contribute to the rich species diversity of insects. Here
The specimens upon which this study is based, were collected from Sichuan province of China in 2016 by sweep nets and yellow pan traps. After the genitalia was dissected, it was placed in a small centrifuge tube containing glycerin and stored in glass tube containing the corresponding specimen (all specimens were stored in alcohol) and deposited in the Entomological Museum of
