The structure of male genital organs in sibling species of the virilis group of Drosophila was examined using methods of multivariate statistics. The differences among these species were estimated using 33 indices and 2 angle parameters. The intraspecific and interspecific correlation structure of the examined characters and the order of their divergence were established. The key characters with respect to forming interspecific differences in the virilis species group were identified. Based on these results, the relative systematic positions of the sibling species are discussed as well as similarities and differences of the pattern of relationships among the species from that generally accepted for the virilis group.
利用多元统计方法研究了果蝇雄性生殖器的结构。这些物种之间的差异是用33个指标和2个角度参数来估计的。确定了所研究性状的种内和种间相关结构及其分化顺序。识别出了在果蝇雄性生殖器物种组中形成种间差异的关键性状。基于这些结果，讨论了姊妹种的相对系统位置，以及这些物种间关系模式与果蝇雄性生殖器组普遍接受的模式之间的异同。
