Examined specimens were purchased from a native collector. They were dried and deposited in Ehime University Museum, Matsuyama, Japan (EUMJ). Male genitalia were treated with 10% potassium hydroxide at 60°C for approximately one hour. The genitalia were rinsed with 70% ethanol and mounted in glycerine for observation and illustration. The dissected genitalia were then stored in microvials with glycerine and pinned with the specimen. Morphological observations were made under a Nikon SMZ1500 stereomicroscope. Genitalia illustrations were drawn under a Leica M205C stereomicroscope. All photographs were taken by a Nikon Digital Sight DS-Fi1 camera attached to a Leica S8APO stereomicroscope. Several partially focused images were combined and post-processed using Adobe Photoshop® CS6. Terminology follows
