Comparative Study of the Reproductive System of Two Species of Hoplia (Coleoptera: Scarabaeidae: Hopliinae)

The female and male reproductive systems of Hoplia subcostata Bates and Hoplia squamifera Burmeister are described. The female reproductive systems of both species are similar, consisting of two ovaries, each with six ovarioles and two lateral oviducts, the common oviduct, bursa copulatrix, spermatheca with its gland, two accessory glands, and three pairs of genital plates. However, the forms of genital plates of H. subcostata and H. squamifera differ. The male reproductive systems in both species also are similar, but the aedeagus differs in shape and proportions. The reproductive system in males consists of two testes, each testis with six follicles, two vasa deferentia, two accessory glands, ejaculatory bulb, ejaculatory duct, and an aedeagus.
