生殖器
Reproductive system: Penis is elongate and broader than vagina, epiphallus and spermatheca. Epiphallus is swollen and connected to penis laterally near its posterior end, by a long thin duct, which is thinner than vas deferens. Vagina as long as penis and almost as narrow as vas deferens. There are no accessory glands. The spermatheca is elongate and relatively short.
