The male genital and pregenital skeleton and musculature were studied in males of the following species of the Muscidae subfamily Azeliinae: Drymeia firthiana (Huckett, 1965), Drymeia longiseta Sorokina & Pont, 2015, Drymeia segnis (Holmgren, 1883), Thricops nigritellus (Zetterstedt, 1838), Thricops hirtulus (Zetterstedt, 1838), Hydrotaea dentipes (Fabricius, 1805), Muscina stabulans (Fallén, 1817), and Muscina levida (Harris, 1780). Descriptions and figures of the genital sclerites and muscles of D. firthiana and M. stabulans are given. A comparison was made between the genital segments and muscles of previously studied species of Mydaeinae and Muscinae and those of the Azeliinae. Based on the structure of the skeleton and muscles of syntergosternite VII + VIII and the phallapodeme muscles, significant differences were found between the subfamily Azeliinae and the subfamilies Mydaeinae and Muscinae. The basal position of the Azeliinae within the family Muscidae was confirmed. A comparison of the genital segments and muscles of the Muscidae with those of the Scathophagidae (Scathophaga stercoraria (Linnaeus, 1758)) and Anthomyiidae (Delia platura (Meigen, 1826)) was made. Tendencies in reduction of the pregenital segments and musculature, as well as of the phallapodeme muscles in the evolution of the Muscoidea have been revealed. The complete set of phallapodeme muscles in the Scathophagidae and Anthomyiidae corresponds to the basal state, and therefore the structure of the genital sclerites and muscles in the Muscidae shows a certain degree of reduction. The progressive changes in the Muscidae from the Azeliinae through the Mydaeinae to the Muscinae were traced.

根据雄性末端的肌肉组织，确定蝇亚科在蝇科（双翅目）中的位置

研究了蝇科 Azeliinae 下列物种的雄性生殖器和前生殖器骨骼和肌肉组织：Drymeia firthiana (Huckett, 1965)、Drymeia longiseta Sorokina & Pont, 2015、Drymeia segnis (Holmgren, 1883)、Thricops nigritellus (Zetterstedt) , 1838)、Thricops hirtulus (Zetterstedt, 1838)、Hydrotaea dentipes (Fabricius, 1805)、Muscinastabulans (Fallén, 1817) 和 Muscina levida (Harris, 1780)。给出了 D. firthiana 和 M.stabulans 的生殖器骨片和肌肉的描述和图形。对先前研究的Mydaeinae 和Muscinae 物种与Azeliinae 物种的生殖器节段和肌肉进行了比较。根据syntergosternite VII + VIII 的骨骼和肌肉结构以及阴茎足肌肉，发现Azeliinae 亚科与Mydaeinae 和Muscinae 亚科之间存在显着差异。确认了蝇科中蝇亚科的基础地位。对蝇科动物的生殖器节段和肌肉与Scatophagidae (Scatophaga stercoraria (Linnaeus, 1758)) 和 Anthomyiidae (Delia platura (Meigen, 1826)) 的生殖器节和肌肉进行了比较。已经揭示了粘蝇总科进化过程中前生殖器节段和肌肉组织以及阴茎足部肌肉减少的趋势。鲫科和花蝇科的完整的阴茎足部肌肉对应于基础状态，因此蝇科的生殖器骨片和肌肉的结构表现出一定程度的减少。追踪了蝇科从 Azeliinae 到 Mydaeinae 再到 Muscinae 的渐进变化。
