Abstract

The sting apparatus of aculeate Hymenoptera is derived from the ovipositor and is their most prominent apomorphy. In contrast to the frequently analysed sclerites of the sting apparatus, the associated musculature has largely been neglected. In this study, we use micro-computed tomography to present a detailed description of the musculature of the sting apparatus of Ampulex compressa (Ampulicidae) and Sceliphron destillatorium (Sphecidae). We found that 12 of 15 muscles corresponding to the sting apparatus are homologous between both species examined and 13 muscles in comparison with Hymenoptera described in the literature. All muscles identified as critical for the act of stinging were found in both species. Moreover, we found the ventral tergum 8-tergum 9 muscle and the tergum 8-tergum 8 muscles in A. compressa and the second valvifer-second valvifer muscle in S. destillatorium. For the first time, we describe the ventral tergum 8-tergum 9 muscle and the second valvifer-second valvifer muscle that interconnects both body sides, in Hymenoptera.

膜翅目，扁腹麻蜂科(amamlex compressa)和刺腹麻蜂(Sceliphron destillatorium)刺器肌肉组织形态的比较

有刺膜翅目昆虫的刺器由产卵器演化而来，是其最突出的刺器。与经常分析的刺痛器官的硬膜相反，相关的肌肉组织在很大程度上被忽视了。在这项研究中，我们使用微型计算机断层扫描来详细描述压肢壶(ampllex compressa)和刺腹壶(Sceliphron destillatorium)的刺器。我们发现与刺器对应的15个肌肉中有12个在两种被检查的物种之间是同源的，与文献中描述的膜翅目昆虫相比，有13个肌肉是同源的。在这两个物种中都发现了所有被认为对刺痛行为至关重要的肌肉。此外，我们还发现了压缩松鸡的腹侧三叶8-三叶9肌和三叶8-三叶8肌，以及腐烂松鸡的第二瓣-第二瓣肌。在膜翅目昆虫中，我们首次描述了腹侧三瓣肌和连接身体两侧的第二瓣肌。

期刊介绍： Founded in 1857 as Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift is one of the World''s oldest international journals of systematic entomology. It publishes original research papers in English on the systematics, taxonomy, phylogeny, comparative morphology, and biogeography of insects. Other arthropods are also considered where of relevance to the biology of insects. The geographical scope of the journal is worldwide. Deutsche Entomologische Zeitschrift (DEZ) is dedicated to provide an open access, high-quality forum to contribute to the documentation of insect species, their distribution, their properties, and their phylogenetic relationships. All submitted manuscripts are subject to peer-review by the leading specialists for the respective topic. The journal is published in open access high-resolution PDF, semantically enriched HTML and machine-readable XML versions.
