摘要

摘要对1826年的一种Psilidae-Chyliza vittata Meigen的雄性生殖器肌肉组织进行了研究。在这里，我们首次描述了Imantimyia nigrifrons (Macquart, 1835)、Loxocera aristata (Panzer, 1801)、Chamaepsila humeralis (Zetterstedt, 1847)、Psilosoma audouini (Zetterstedt, 1835)和Psila nigripalpis Shatalkin(1983)的男性生殖器肌肉。结果表明，假蝇科动物具有生殖前和生殖硬膜和肌肉的二次对称，并减少了与射精apodeme (apomorphy)减少有关的syntergosterite VII + VIII;肌肉M25也不见了。该家族显示了以不同方式实现的前生殖器和生殖器骨骼和肌肉的压实。分支[[[Chyliza] + [[Imantimyia + Loxocera] + [Chamaepsila + [Psilosoma + Psila]]]由几个突触形态支持。

Skeleton and Musculature of the Male Genitalia in Psilidae (Diptera) and Their Implications for the Phylogeny

Abstract

We have previously studied the musculature of the male genitalia in one species of Psilidae—Chyliza vittata Meigen, 1826. Here, we describe for the first time the male genital muscles of Imantimyia nigrifrons (Macquart, 1835), Loxocera aristata (Panzer, 1801), Chamaepsila humeralis (Zetterstedt, 1847), Psilosoma audouini (Zetterstedt, 1835), and Psila nigripalpis Shatalkin, 1983. It is shown that Psilidae are characterized by secondary symmetry of the pregenital and genital sclerites and muscles, and by reduction of the syntergosternite VII + VIII, which is correlated with reduction of the ejaculatory apodeme (apomorphy); the muscles M25 are also absent. The family shows compaction of the pregenital and genital skeleton and muscles realized in different ways. Clades [[[Chyliza] + [[Imantimyia + Loxocera] + [Chamaepsila + [Psilosoma + Psila]]] are supported by several synapomorphies.

期刊介绍： Entomological Review publishes papers dealing with all aspects of theoretical and applied entomology; and covers systematics, faunistics, zoogeography, evolution, ecology, morphology, physiology of insects, spiders and mites; as well as biological and chemical control of pests. It is one of the few entomological journals with a broad coverage.
