This article introduces the results of a study of three families of Nepomorpha and is the last part of a series of studies that sums up our work on the morphologies of the antennal sensory structures in this taxon. The morphologies and distribution of the sensilla in the families Notonectidae, Pleidae and Helotrephidae were studied under a scanning electron microscope. Six main types (sensilla trichodea, chaetica, campaniformia, basiconica, ampullacea and coeloconica) and ten subtypes (five subtypes of sensilla trichodea and five subtypes of sensilla basiconica) were described. The results were compared with other studies on the antennal sensilla of Nepomorpha in order to assess evolutionary changes within the infraorder. With the use of cladistics analysis, the monophyly of the families Nepidae, Micronectidae, Corixidae and Gelastocoridae was supported. On the other hand, the occurrence of some clades forming superfamilies was weakly supported by bootstrap analysis. These results, supported by presence of the numerous autapomorphies, suggest that antennal sensilla evolved within inner groups.
本文介绍了对三个负子蝽科家族的研究结果，是总结我们在该分类单元触角感觉结构形态学方面工作的系列研究的最后一部分。在扫描电子显微镜下研究了划蝽科、仰蝽科和负蝽科中感器的形态和分布。描述了六种主要类型（毛形感器、刺形感器、钟形感器、锥形感器、瓶形感器和腔锥形感器）和十种亚型（五种毛形感器亚型和五种锥形感器亚型）。将结果与其他关于负子蝽科触角感器的研究进行比较，以评估该亚目内的进化变化。通过支序分析，支持了负蝽科、小划蝽科、仰蝽科和蟾蝽科家族的单系性。另一方面，一些形成总科的分支的出现通过自展分析得到的支持较弱。这些结果，在众多自有衍征存在的支持下，表明触角感器在内部类群中进化。
