【摘要】 研究湖南棒蝠蛾(NapialushunanesisChuetWang)生殖系统的形态构造。分为雌性内部生殖器官、雌性外部生殖器官、雄性内部生殖器官及雄性外部生殖器官四部分。雌性内生殖器中,卵巢为多滋式,一对,各由四根卵巢管组成,两组卵巢管汇合成中输管通外生殖腔,外方开口为产卵孔;受精囊为肾形,通过受精囊管与生殖腔相通,在受精囊顶端有分叉的受精囊腺;无附腺。雌性外生殖器由袋状交配囊和产卵器组成;无导精管。雄性内生殖器,有睾丸一对,各呈四裂花瓣状,外被淡绿色睾丸膜;输精管一对,基部与肾形贮精囊中部相连;贮精囊端部具附腺。雄性外生殖器构造复杂,抱器瓣无钩,背兜前下方有一瘦长叶,外缘有钩齿,囊形突狭长

【Abstract】 This paper deals with the anatomy of the reproductive system of the Napialus hunanensis Chu et Wang. The internal and external organs of both sexes are described. In the femals, the internal reproductive organs are composed of a pair of ovaries, each of which consists of four polytrophic ovarioles. A pair of lateral oviducts, each measuring 1mm in length, unite posteriorly to form the oviductus communis of 0.5~1mm long. Spermatheca is spherical, no accessory glands. The essential parts of the reproductive system in the female are the bursa copulatrix and the ovipositor, no seminal duct. On the part of the internal organs, there are a pair of testes; two testes of opposite sides are closely united as a single round organ enclosed in a light green scrotum. The vasa deferentia are paired narrow tubes about 10mm in length and the basal section of each vasa forms the seminal vesicles. The external genitalia of the male is extremely complex. There is not hook in the valvale. There is a elongate lobe with tooth along exmargin under the tegumen, saccus elongate. The structure of the spermatophore is examined and described.
