“…Moreover, attachment sites of muscles M18 (between sternites VIII and IX) confirm the homology of the hypandrium (sternite IX) as the narrowly sclerotized stripe between gonocoxite bases of both Araucoderus and Nothoderus (Figures 1E, 4A, 5B). Localization of these muscle attachment sites is reliable evidence of the hypandrial origin of the sclerites, as it was revealed by us for DipteraCyclorrhapha (Galinskaya and Ovtshinnikova 2015a, b, Ovtshinnikova and Galinskaya 2016a). Merging of dorsal bridge with gonocoxites is confirming according to attachment sites of muscles M5 ( M5 connecting anterolateral parts of epandrium to lateral thickenings of dorsal bridge of paramere in the point of connection of pm db with gonocoxites) (Figure 6B, C).…”

“…Study of the musculature is helpful not only for specifying the functions of genital sclerites, but also for revealing the homology of some poorly traced structures (Ovtshinnikova and Yeates 1998, Ovtshinnikova and Galinskaya 2016b, 2017, Galinskaya et al 2018). Based on morphogenetical regularities formulated by Matsuda (1976) and verified by Ovtshinnikova (1989) and Friedrich and Beutel (2008), characters associated with muscles are confirmed to be more stable than those associated with sclerites and therefore can be used successfully in phylogenetic studies; morphological series of different species are especially productive for such studies.…”

The structure of the male terminalia and their musculature of species of tanyderid genera Araucoderus Alexander, 1929 from Chile and Nothoderus Alexander, 1927 from Tasmania are examined and compared with each other and with published data on the likely relatives. The overall pattern of male terminalia of both genera is similar to those of most Southern Hemisphere genera, with simple curved gonostyli, lobe-like setose parameres, and setose cerci inconspicuous under the epandrium. Both genera have terminalia similarly rotated by 180° (and 90° as an intermediate stage); rotation may be either clockwise or counterclockwise. However, the similar patterns are realized differently: segment VIII is the decreased and asymmetrical due to completely membranose tergite VIII in Nothoderus (the first record of such modification in Tanyderidae), but narrow and symmetrical in Araucoderus. Accordingly, pregenital muscles are very different between the genera. Based on localization of muscle attachment sites, the hypandrial origin of the stripe between gonocoxites is shown in both genera, and entire membranization of tergite VIII and partial membranization of hypoproct is shown in Nothoderus. Tanyderidae are characterized by highly specialized sclerites and muscles of male terminalia and provide no evidence of relationship with previously studied members of Psychodidae, Blephariceridae and Ptychopteridae.

“…Two pairs of apodemes are present in at least some Odonata (Klass, 2008a) and some Orthoptera (Snodgrass, 1935a), though other orthopterans lack ventral sclerites entirely (Consoulas & Theophilidis, 1992). In the Endopterygota, sternal apodemes are absent in various Diptera (Bonhag, 1951; Ovtshinnikova & Galinskaya, 2016; Ovtshinnikova, Galinskaya, & Lukashevich, 2018; Pollock, 1999), Siphonaptera (Snodgrass, 1947), and the neuropteroid groups Chrysopidae (Miller, 1933) and Raphidioptera (Matsuda, 1957). In Hymenoptera, two pairs of sternal apodemes, anterior and lateral, occur in at least the anterior abdomen of Urocerus (“symphyta”), and in all the pregenital metasomal segments of Apis (Short, 1959; Snodgrass, 1942).…”

Recent studies of insect anatomy evince a trend towards a comprehensive and integrative investigation of individual traits and their evolutionary relationships. The abdomen of ants, however, remains critically understudied. To address this shortcoming, we describe the abdominal anatomy of Amblyopone australis Erichson, using a multimodal approach combining manual dissection, histology, and microcomputed tomography. We focus on skeletomusculature, but additionally describe the metapleural and metasomal exocrine glands, and the morphology of the circulatory, digestive, reproductive, and nervous systems. We describe the muscles of the dorsal vessel and the ducts of the venom and Dufour's gland, and characterize the visceral anal musculature. Through comparison with other major ant lineages, apoid wasps, and other hymenopteran outgroups, we provide a first approximation of the complete abdominal skeletomuscular groundplan in Formicidae, with a nomenclatural schema generally applicable to the hexapod abdomen. All skeletal muscles were identifiable with their homologs, while we observe potential apomorphies in the pregenital skeleton and the sting musculature. Specifically, we propose the eighth coxocoxal muscle as an ant synapomorphy; we consider possible transformation series contributing to the distribution of states of the sternal apodemes in ants, Hymenoptera, and Hexapoda; and we address the possibly synapomorphic loss of the seventh sternal–eighth gonapophyseal muscles in the vespiform Aculeata. We homologize the ovipositor muscles across Hymenoptera, and summarize demonstrated and hypothetical muscle functions across the abdomen. We also give a new interpretation of the proximal processes of gonapophyses VIII and the ventromedial processes of gonocoxites IX, and make nomenclatural suggestions in the context of evolutionary anatomy and ontology. Finally, we discuss the utility of techniques applied and emphasize the value of primary anatomical research.

“…Both the sclerites and the muscles of pregenital segments VI-VIII and part of IX are asymmetrical, and the structure of sclerites and muscles of the pregenital and genital segments differs significantly in different families of Cyclorrhapha. Earlier, the musculature of male terminalia in muscoid flies was studied in detail on members of the families Muscidae (Ovtshinnikova, 1989;Ovtshinnikova et al, 2018Ovtshinnikova et al, , 2019, the Fanniidae (Sorokina & Ovtshinnikova, 2022) and only partially on the Anthomyiidae (Delia platura Meigen, Fucellia tergina Zetterstedt) (Hennig, 1976) and the Scathophagidae (Ovtshinnikova, 1994). In previous studies by the authors, the apomorphic transformations of the muscles of the pregenital segments of males important in the phylogenetic branching of the Calyptratae have been identified.…”

The abdominal and pregenital segments and genitalia were studied in males of Zaphne barbiventris (Zetterstedt, 1845) and Delia fabricii (Holmgren, 1872) (Anthomyiidae). The examined species are very similar in the structure of the sclerites and muscles of their terminal segments. Differences between Delia Robineau‐Desvoidy, 1830 and Zaphne Robineau‐Desvoidy, 1830 were found only in the structure of the pregenital segments and their muscles. Delia has well‐developed and well‐identified tergite VI, while tergite VI of Zaphne is fused in syntergosternite VI + VII + VIII as indicated by the insertion of muscles of ITM 5 running from tergite V. Within members of the muscoid grade, the skeleton and musculature of male terminalia of the Anthomyiidae were similar to that in the subfamily Azeliinae of the Muscidae and the Scathophagidae. The complete set of phallapodeme muscles, as well as the complete set of muscles of the pregenital sclerites and the position of cercal muscles M 26, has shown that the Anthomyiidae have more plesiomorphic character states than other members of the muscoid grade. Descriptions and figures of the terminal sclerites and muscles of Zaphne barbiventris are provided.
