描述了缘蛾蜡蝉Salurnis marginella(Guérin-Meneville)、八点广翅蜡蝉Ricania speculum(Walker)、斑衣蜡蝉Lycorma delicatula(White)及中华彩象蜡蝉Raivuna sinica(Walker)等4种蜡蝉的雌性生殖系统,并提供了相应的形态特征图。研究结果表明:4种蜡蝉的雌性内生殖系统均为双孔类型;交配管通过阴道与交配囊相连,不直接与交配囊相连;卵巢管为端滋式;阴道、交配囊和受精囊均为双层膜质结构,而卵巢管、侧输卵管则为单层膜质结构。明确了蜡蝉总科昆虫总输卵管与侧输卵管的连接方式,总输卵管为一端固定于阴道内膜,另一端游离于阴道内膜与外膜之间,朝向侧输卵管合并处的透明膜质管状结构。此外,雌性生殖系统中的交配囊、第1产卵瓣、阴道附腺、内生殖突、内生殖瓣等形态特征差异较大。研究标本保存于西北农林科技大学昆虫博物馆。 相似文献

Abstract. Fifty of the fifty-six species of the genus Apamea known from North America and three Palaearctic species were analysed for lock-and-key characters in their internal genitalia, mainly in the male vesica and the female bursa copulatrix. There were an average of 4.5 such characters per species, structurally corresponding in the two sexes. Anatomically they form a postcopulatory but prezygotic isolation mechanism. In some closely related species, the internal genitalia are very similar, but these species have a precopulatory isolation mechanism in the presence or absence of male abdominal coremata. Closely related species did not have more lock-and-key characters than unrelated species, which is taken to indicate absence of character displacement. The anatomical distribution of the lock-and-key characters was examined and the organs of eight species are illustrated.
The lock-and-key hypothesis has been abandoned by several earlier authors but mainly on consideration of external genitalia. In Apamea the invariable functional correspondence between sexes in the sperm transferring organs, and the overall species-specifity of characters but non-existence of interspecific differences under a precopulatory mechanism indicate that (a) lock-and-keys are functioning and (b) they act as isolation mechanisms. Alternative hypotheses of genitalic evolution are reviewed. 相似文献

记述采自广西大明山的蚋属1新种,大明蚋Simulium(Simulium)damingensesp.nov.(图1~15)。新种依其两性尾器特征,隶属于淡足蚋组malyschevi group(Takaoka and Davies,1996)。新种雌虫第7腹节有分支毛丛,雄虫生殖腹板的形状,与印度的S.(S.)hirtipannus Puri和日本的S.(S.)nacojapi Smart近似。但新种雌虫食窦弓光滑,爪简单,足的颜色及幼虫后颊裂伸达亚颏后缘等特征可与以上两种相区别。报道自日本的S(S.)kyushuense Takaoka,1978的幼虫后颊裂延伸达亚颏后缘,但其雌虫第7腹节无分支毛丛可资鉴别。正模♀,副模7♀♀,5♂♂,21蛹,6幼虫,均采自广西大明山小溪急流向阳水草中。模式标本存放于贵阳医学院生物学教研室。 相似文献

The male and female of Polycentropus cianficconiae sp. n. (Peloritani Mountains, Northeast Sicily) are described. This new species is related to P. divergens Mosely, 1930, of which the variability of some characters of male genitalia is examined. Female genitalia of the new species are compared to those of P. divergens, P. malickyi Moretti, 1981 and P. mortoni Mosely, 1930. The characters of female genitalia are useful for evaluating the relatedness and differences among the species. They agree with the findings of the study on male genitalia. 相似文献
