Stylops nevinsoni Perkins, 1918: 71 , F. Type locality: Great Britain . ?= Stylops transversa Pasteels, 1949: 191 , M, F. Type locality: Belgium , Uccle. Supposed new junior subjective synonym. Hosts. Andrena ( Andrena ) synadelpha Perkins, 1914 ( PERKINS 1918 ), Andrena ( Andrena ) fulva (Müller, 1766) ( PASTEELS 1949 ) . DNA barcode sequences. KF803457 , KF803458 , KF803462 , KF803533 . Notes. Distances between DNA barcode sequences of Stylops from the subgenus Andrena and the other host subgenera are 8–17 % in the West Palaearctic Region ( JŮZOVÁ et al. 2015 ). Stylops praecocis , which also parasitizes bees of the subgenus Andrena , seems to be very closely related and their DNA barcode sequences differ only 1 % in base composition. However, phylogenetic study suggests two distinct Stylops clades for early spring and late spring Andrena bee hosts ( JŮZOVÁ et al. 2015 ). In addition, significant morphological differences were found in first instars from A. fulva (likely S. nevinsoni ) and A. praecox (likely S. praecocis ) ( BORCHERT 1963 ). For these reasons, we decided to assign both names to valid species; however, more research is needed in this problem.
