REMARKS. Examined Examined Stylops specimens from Andrena (Truncandrena) truncatilabris Morawitz, 1878 is probably a new species. It belongs to a clade D of undescribed Stylops species associated with Andrena hosts from subgenus Truncandrena . Interestingly, Stylops from Andrena (Truncandrena) varia Pérez, 1895 was in a different clade, suggesting that two different Stylops species may utilize Andrena hosts from subgenus Truncandrena ( Lähteenaro et al., 2023) . Therefore, until additional data is provided, it should remain a separate taxon. In European Russia A. (Tr.) truncatilabris is a rare species.

As the result of this study, eight species of strepsipterans are recorded from the European part of Russia, of them Kinzelbachus friesei , Stylops andrenaphilus , S. spreta , S. cf. aino and Stylops sp. are new for the fauna of Russia. Whether or not the Stylops species parasitizing the European Andrena (Hoplandrena) rosae is the same as the one in Japan and Korea needs to be verified, unfortunately no DNA barcodes are available for S. aino nor for the European parasite of A. (H.) rosae . Furthermore, the identity of the parasite of Andrena (Truncandrena) truncatilabris remains unresolved, no DNA barcodes are available, and it has not previously been recorded as a host of a Stylops species.

Many species recorded here are widely distributed in Europe and their presence in European Russia is unsurprising. However, despite the records and material listed above, the order Strepsiptera remains quite poorly studied in Russia, and new country records and further details relating to host species and distributions can still be expected.
