Specimens were collected by Berlese-Tullgren funnels and preserved in 80% ethanol. The material was mounted on slides in Hoyer’s solution and dried in an oven at 45 °C for identification. Drawings were done with the aid of a phase contrast microscope. The type specimens are deposited in Shanghai Natural History Museum
