“…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).…”

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.

“…The cerci, surstyli, epandrium and the subepandrial sclerite are here referred to here as the "external components of the genitalia"; these form an outer containing capsule for the inner structures that have sometimes been termed the "hypandrial complex" (eg. Galinskaya & Ovtshinnikova (2015); Lonsdale & Marshall (2010)).…”

The Acalyptratae are a diverse, heterogenous assemblage of dozens of families of “higher flies” in the Schizophora (Diptera). There are ten acalyptrate superfamilies, two of which are reviewed and redefined here at the family-group level: Diopsoidea and Nerioidea. The superfamily Diopsoidea includes seven families: Diopsidae (two subfamilies and two tribes), Gobryidae, Megamerinidae, Nothybidae, Psilidae (three subfamilies), Somatiidae and Syringogastridae. The superfamily Nerioidea also includes seven families: Cypselosomatidae, Fergusoninidae, Micropezidae (five subfamilies), Neriidae, Pseudopomyzidae, Tanypezidae and Strongylophthalmyiidae. All 14 families are redescribed, figured and keyed, including notes on subordinate family-level groups. Homologies for external and genitalic characters are established, and the superfamilies and their family-level groups are discussed. A morphological phylogenetic analysis is provided, including representatives from all family-level groups in both ingroup superfamilies, as well as twelve outgroup taxa from five other acalyptrate superfamilies. Both superfamilies were supported as monophyletic, although both the Diopsoidea and its basal branches were supported by highly homoplasious characters and are here only tentatively accepted; a relationship between Diopsidae, Syringogastridae and Megamerinidae is strongly supported. Nerioidea is a well-defined group divided into three lineages, including one containing Pseudopomyzidae, Cypselosomatidae and Fergusoninidae, the latter of which was previously considered to be related to the family Agromyzidae (Opomyzoidea). Diopsoidea and Nerioidea were not found to be related.

a russian academy of sciences, Zoological institute, st. Petersburg, russia; ABSTRACT Musculature of male genitalia is for the first time revealed and described in Celyphidae (Diptera). We have defined the specific features of sclerites and muscles of Celyphidae male genitalia on the basis of the comparative analysis of these anatomical structures in other acalyptrate flies. The secondary symmetry of male pregenital and genital sclerites, muscles, and merged segments 7 and 8 (forming syntergosternite 7 + 8) in Celyphidae possibly indicates that this family is closely related to Lauxaniidae and Diopsoidea. Moreover, Celyphidae is similar to Psilidae in terms of syntergosternite 7 + 8 decreased, pregenital muscles partially reduced, hypandrial structures partially reduced, muscles M1 and M2 merged, and muscle M25 reduced. Celyphidae are characterized by the presence of pregonites (gonopods sensu) and associated muscles M42. We suppose that pregonites (and corresponding muscles) connected with hypandrium originated independently in different groups of Cyclorrhapha.
