Panurgus clypeatus Eversmann, 1852: 62 , ♀, not ♂.

Type locality: Irkutsk ( Russia).

Published (original) locality: “in campis transuralensibus”.

Lectotype (designated here): ♀, golden circle // Irkutsk [ Russia, Irkutsk Province, Irkutsk, 52°17′N 104°18′E] // clypeatus Ever. , ♂ [handwritten by E. Eversmann] // Panurginus labiatus Ev. , ♀ [sic!], V. Popov det., styl.[opidae]! // Lectotypus Panurgus clypeatus Eversmann, 1852 , design. Astafurova & Proshchalykin 2024 <red label> // P. niger Nyl. Astafurova det. 2023 // Zoological Institute St. Petersburg INS_HYM_0002528.

Current status. Panurginus niger Nylander, 1848 , syn. nov.

Remarks. E. Eversmann (1852: 62) described this species as a male when it was actually a female. He was probably misled by the yellow clypeus, which is typical of males. V. Popov (1946: 106), after studying the type specimen, corrected this error and synonymised this species with Panurginus labiatus ( Eversmann, 1852) . And for a long time Panurgus clypeatus Eversmann, 1852 was accepted as a junior synonym of Panurginus labiatus ( Eversmann, 1852) . For the present study a lectotype was designated and then additional material from the genus Panurginus from the Urals and Siberia was examined. The lectotype specimen has brownish wings and light brown veins (vs white wings and yellow veins in P. labiatus ) and is conspecific with Panurginius niger Nylander, 1848 , which is widely distributed in the Eastern Palaearctic. The lectotype has an abnormally yellow clypeus and among the bees studied, there was one female of P. niger with a partially yellow clypeus ( Fig. 34c ), whereas the other specimens had a typically black clypeus. Thus, Panurgus clypeatus Eversmann, 1852 is recognised here for the first time as a junior synonym of Panurginus niger Nylander, 1848 .

Distribution. See Panurginus dubius Osytshnjuk, 1995 .
