The results showed that the male internal reproductive system of adult is composed of testes, seminal vesicle, vas deferens, accessory gland, and ejaculatory duct. The seminal vesicle is developed from specialized vas deferens. The male external genitalia is consists of three parts, namely aedeagus, manubrium and tegmen, but have no clasper. The female internal reproductive system of adult is composed of ovary, lateral and median oviduct, spermatheca, and bursa copulatrix. The two ovaries are symmetrical, each consisting of 5 panoistic ovarioles. The female external genitalia is composed of dorsovalvula, intervalvula, and ventrovalvula. Ovarian development can be divided into 4 grades based on the morphological characteristics of ovaries, including nooocyte stage, egg maturation stage, ovipositing stage , and post-ovipositing stage. Each stage shows significant differenc
