| Abstract: | Rheocricotopus (Psilocricotopus) constrictus sp. nov. from China is described as male imago. The species is closely related to R. (P.) orientalis Wang, R. (P.) calviculus Wang et Saether and R. (P.) villiculus Wang et Saether,forming orientalis group Wang and Saether. The species is distinguished from the known species of the group by having a long claviform inferior volsella and a constricted anal point. A key to the adult males of the species group is presented. |
