Genus Camptomyia Kieffer, 1894

Camptomyia , a further asynaptine genus of global distribution, had previously 73 species in the world, 31 in Europe, and three in Germany ( Gagné & Jaschhof 2021; Jaschhof & Jaschhof 2021a, 2021b, 2022, 2023). Males of about two thirds of the European species can be identified by use of the available literature ( Jaschhof & Jaschhof 2013, 2019b, 2021a); recognition of the rest is problematic since their published descriptions, especially illustrations, lack accuracy and detail. Of the 14 species of Camptomyia addressed here, one is new to science and 13 are new additions to the German fauna. One of these taxa, C. multinoda ( Felt, 1908) , is a potential complex of species, which will require further study in a broader geographic scope to resolve. The taxonomy of the C. corticalis (Loew, 1851) group of species poses another unresolved problem of considerable complexity ( Jaschhof & Jaschhof 2013, 2019b). The present project found six species of this group, each with a distinctive morphology, whose identity could not be resolved (labeled C. sp. MJDE1 to C. sp. MJDE 6 in the list at the end of this paper). CO1 sequences were obtained of five of these species. Unexpectedly, even C. corticalis sensu Jaschhof & Jaschhof (2013) , whose occurrence in Germany had been noted earlier ( Jaschhof & Jaschhof 2021b), emerged here in three separate genetic clusters, representing the genuine C. corticalis ( Jaschhof & Jaschhof 2013: figs 164a‒d and 164f‒h but not 164e) and two possibly unnamed species (C. sp. MJDE5 and C. sp. MJDE6). Pending a definite clarification of the issue, I regard C. corticalis as an aggregate species.
