Aspöck et al. 1980; Rehfeldt 1989; H. Aspöck et al. 2001; Monserrat et al. 2014; Oswald 2025) (Fig. 25). Comparative notes. Deleproctophylla dusmeti may be difficult to distinguish from its two congeners in western Europe, D. australis and D. bleusei. The wing patterns traditionally used to differentiate these species are unreliable and exhibit high individual variation (Fig. 4). The diagnostic characters of D. dusmeti include a triangular-shaped hindwing (in contrast to the elongated hindwing of D. australis) and a male ectoproct branch that protrudes at mid-length (whereas in D. australis and D. bleusei the branch arises after mid-length) (Figs 13 A, 14 A). Remarks. D. dusmeti has been reported from several Asian countries, including Azerbaijan, Turkey, and Pakistan (H. Aspöck et al. 2001; Canbulat and Kiyak 2004; Canbulat 2007; Dobosz and Ábrahám 2007; Koçak and Kemal 2012; Hassan et al. 2019; Monnerat and Ábrahám 2020; Hassan and Liu 2021; Oswald 2025). However, the examination of the specimens assigned to the “ dusmeti - like form ” (see H. Aspöck et al. 1980) suggest that these instead belong to D. australis, representing individuals without forewing marking, a common trait in eastern populations of this species. The vague report from Pakistan (Hassan et al. 2019; Hassan and Liu 2021; Oswald 2025), which lacks any locality information cannot be verified at present. It may actually refer to D. dandizenor sp. nov., another species with unmarked forewing. The current observations suggest that D. dusmeti is exclusively a western European species. Deleproctophylla dusmeti is typically distinguished from D. australis by the absence of forewing spots. However, some populations along the southeastern coast of France include individuals with marked forewings mixed with unmarked ones (Fig. 4 H). The study of genital morphology and species delimitation analyses confirm that these specimens belong to D. dusmeti (Fig. 1). These spotted individuals are likely the source of records of D. australis in southern France, despite this species is absent from the French mainland (though it is present in Corsica). The distributions of D. dusmeti and D. australis do not overlap, being separated by a relatively small geographic gap along the northern Tyrrhenian coast of Italy (Fig. 25).
