Panurginus nitidulus Morawitz, 1889: 357 , ♀.

Type locality: Songpan, Sichuan ( China).

Published (original) locality: “Sse-tschuan: Tschatshaku”.

Lectotype (designated here): ♀, Kansu, Tschatshaku [ China, Sichuan, 30 km N of Songpan, 32°40′N 103°40′E], Potanin [leg.]// к.[оллекциЯ]Ф.Моравица [collection of F.Morawitz] // [handwritten by F. Morawitz] // Lectotypus Panurginus nitidulus F. Morawitz , ♀, Astafurova design., 2010 <red label> // Zoological Institute St. Petersburg INS_HYM_0002502 .

Paralectotype: ♀, the same label as in the lectotype.

Current status. Panurginus nitidulus Morawitz, 1889 , sp. resurr.

Remarks. F. Morawitz (1989) described two species from Sichuan ( China): Panurginus nitidulus and P. picipes (= Panurginus picitarsis Cockerell, 1912 , nom. nov.). The females of P. nitidulus and the males of P. picipes have similar sculpture on the mesoscutum and metasomal terga. This gives the impression that both sexes are conspecific. K. Warncke (1987: 94) synonymised P. nitidulus with P. picipes . However, the female of P. nitidulus has a rounded vertex, whereas the male of P. picipes has an angular vertex. In addition, the body size of P. nitidulus (6.0– 6.5 mm) is smaller than that of P. picipes (7.5 mm), whereas females in Panurginus are on average larger than males. The female of P. nitidulus contradicts this and should be treated as a separate species.

Distribution. China (Sichuan).
