Winnertzia fusca Kieffer 1901

Winnertzia fusca Kieffer, 1901 Morphological identification Jaschhof & Jaschhof (2020b). In their revision of Winnertzia of Sweden, Jaschhof & Jaschhof (2020b) noticed some variation in terminalia characters of male W. fusca. The present project discovered two specimens of a possibly discrete, unnamed Winnertzia close to W. fusca, here labeled W. sp. MJDE59 (BIN BOLD:ACP6306). Reexamination of the morphology of the respective specimens from both Sweden and Germany is pending. DNA barcode CO1 sequences (653‒654bp) of the two specimens detailed below are available in BIN BOLD:ACU8967. A search in BOLDʼs BIN Database retrieved a further two matches for this BIN, as Diptera sp. from Germany and Cecidomyiidae sp. from Belarus (accessed 25 Aug. 2023). Material examined GERMANY ‒ Baden-Württemberg • 1 ♂; Malsch, Luderbusch; 48°91′61″ N, 8°33′18″ E; elev. 111 m; 12‒26 Apr. 2020; D. Doczkal and K. Grabow leg.; Malaise trap; windthrow of birch trees; BOLD GBDTA10487-21; ZSM-DIP-42309-D01 • 1 ♂; same data as for preceding; BOLD GBDTA10488-21; ZSM-DIP-42309-D02.
