Hosts. Andrena (Taeniandrena) ovatula ( Kirby, 1802) ( KIFUNE et al. 1994, PERKINS 1918), A. (T.) similis Smith, 1849 ( HOFENEDER 1939), A. (T.) albofasciata Thomson, 1870 ( GÜNTHER & ŠEDIVÝ 1957, PASTEELS 1954), A. (T.) ezoensis Hirashima, 1965 ( KIFUNE & HIRASHIMA 1985, KIFUNE & MAETA 1990), A. (T.) wilkella ( Kirby, 1802) ( GÜNTHER & ŠEDIVÝ 1957, LUNA DE CARVALHO 1974, PASTEELS 1954).

DNA barcode sequences. KF803470 , KF803494 , KF803544 .

Notes. PASTEELS (1949: 186) correctly noted that the name proposed by SAUNDERS (1872) is unavailable, and the author of the name is PERKINS (1918).

We suggest a synonymy of S. championi with S. thwaitesi , because S. championi was described based on the same series of specimens collected by G. C. Champion and described also as S. wilkellae . Description of morphological characters presented by PIERCE (1919), especially length of antennal segments, is identical to description provided by PERKINS (1918).

We also suggest synonymization of S. borealis with S. thwaitesi because of very similar DNA barcode sequences between the West and East Palaearctic individuals. The sequences from the Japanese population differ from the European population of this species by only 1.7–1.9 %. Stylops thwaitesi differs from other species in 9–18 % of the DNA barcode sequence base pairs ( JŮZOVÁ et al. 2015).
