摘要: 【目的】利用日本北海道虻类评估和验证外生殖器在分类学上的意义。【方法】将虻类成虫标本浸渍在生理盐水中并置于双目显微镜下通过针和镊子在培养皿中进行解剖并绘图,观察第9背板、第10背板、尾叶、第8腹板、受精囊、受精囊管及生殖叉器的形态特征。【结果】在日本北海道共记录了虻科(Tabanidae) 3亚科7属38种。我们观察并描述了3亚科其中的6属24种的雌性外生殖器的主要特征。亚科之间存在明显差异;然而在一般情况下属之间很难建立一种方法来确定共同点;种之间只有在斑虻属Chrysops中有相似之处,其他属中则比较多样化。因此,亚科鉴定根据第9背板、第8腹板及受精囊足以进行区分,属及种鉴定需要结合第9背板、第10背板、尾叶、第8腹板、受精囊、受精囊管及生殖叉器各自的特征组合在一起才能区分开来。我们也制作了虻类外生殖器的检索表。【结论】和许多其他昆虫一样,外生殖器是虻科的重要分类特征,对于促进分类学和系统学的发展具有重要意义。本研究首次对分布在日本北海道的虻科雌性外生殖器进行了系统研究。

Abstract: 【Aim】 This study aims to estimate and verify the roles of genitalia of tabanids in taxonomy with species from Hokkaido, Japan. 【Methods】 Samples of tabanid adults from Hokkaido soaked in physiological saline were dissected in petri dish by needle and tweezers under a binocular microscope and drawn. The morphological characteristics of the tergites 9 and 10, the cercus, sternite 8, the spermathecae, the spermathecal duct and the genital fork were observed and presented. 【Results】 In total 38 species of 3 subfamilies and 7 genera of tabanids have been recorded from Hokkaido. The main features of the female genitalia of 24 species of 3 subfamilies and 6 genera of tabanids in Hokkaido were observed and described here. There are the differences at the subfamily level. However, among genera, it is difficult to establish a way to determine the common points. Among species, similarities are seen only within the genus Chrysops. In other genera, the species are diversified. Consequently, for subfamily-level classification, the characteristics of tergite 9, sternite 8 and the spermathecae are enough for separation; while for genus and species-level classification, the combined characteristics of tergite 9, tergite 10, the cercus, sternite 8, the spermathecae, the spermathecal duct and the genital fork must be compared. Keys to female genitalia of tabanids are provided. 【Conclusion】 Genitalia is a critical characteristic to classification in Tabanidae as in many other insects, which is significant to facilitate the development of taxonomy and phylogenesis. This is the first systematic study on the female genitalia of the tabanids in Hokkaido.
