Rheocricotopus (P.) villiculus Wang & Saether, 2001 Rheocricotopus (Psilocricotopus) villiculus Wang & Saether, 2001: 238. Rheocricotopus (Psilocricotopus) villiculus – Ashe & O’Connor 2012: 568. Type material Holotype CHINA – Henan • ♂; Xinyang, Mt Jigong, Jigongshan NNR; 31°48′ N, 114°04′ E; 700 m a.s.l.; 11 Jul. 1997; Y.Z. Du leg.; NKU, NKU 012777. Distribution The species is known from Henan, Zhejiang and Jiangsu provinces in Oriental China (Lin et al. 2020: 284 fig. 2). Remarks Although in the original description of this species, the authors (Wang & Saether 2001: 238) wrote: “no humeral pit”, our re-examination of the holotype revealed that the male has large, oval humeral pits. The species is a typical member of the orientalis group, characterized by a pair of posterolateral setal tufts on the tergite IX, which is a unique feature as a discriminator from the other members. However, Wang & Saether (2001: 239) wrote: “The inferior volsella on one side is lost or reduced. It thus may seem unwarranted to describe a species based on a single specimen which, in addition, could be aberrant.” The female, the pupa and the larva are unknown.
