Morphology
The length of the body reported in the descriptions includes the forewings at rest. Male genitalia were prepared using the techniques described by Oman (1949). Morphological terminology follows Dietrich (2005, 2011) and Dworakowska (1993). The genital segments of the specimens examined were macerated in 10% NaOH for 7–10 hours (or boiled for 1–3 minutes), then transferred to glycerin after rinsing in distilled water to remove traces of NaOH (10%) for further research. Male genitalia were drawn using a LEICA m125 microscope and drawings were processed using Adobe Illustrator CS6. Habitus photographs were taken with a KEYENCE VHX-6000 digital camera and optimized with Adobe Photoshop CS6. All specimens studied are housed in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).
