682087B6FF817D44FF1E13ECFD79F93E.taxon	discussion	Remarks. In the latest key to the known Holarctic species of Pagastia (Makarchenko & Hansen 2020, p. 175), the new species keys to couplet 5, P. orientalis / P. altaica, but the anal point of the new species is stout, triangular, and fully sclerotized (Fig. 1 C), which clearly differs from other known members in this genus. Furthermore, the median lobe of the aedeagal complex is also unique, which consists of two parts: the mitten-shaped main body and a dorsal branch which arises basally on the median lobe. The apex of the lateral lobe is also pectinate. Currently, the species is only known from Yunnan Province.	en	Liu, Jun, Tang, Hongqu (2025): Two new Pagastia Oliver (Diptera, Chironomidae, Diamesinae) described from Oriental China.

682087B6FF817D41FF1E141DFA6EFE2F.taxon	discussion	Remarks. The composition of the aedeagal complex of this new species is unique among known Pagastia species. Specifically, the aedeagal complex in P. shennong sp. nov. has a granulated apex of the median lobe and a basally arising pectinate dorsal branch. In addition, the pale scutellum, the outer heel in the apex of the gonostylus, separate it from the other known species in the genus. Currently, the species is only known from the type locality.	en	Liu, Jun, Tang, Hongqu (2025): Two new Pagastia Oliver (Diptera, Chironomidae, Diamesinae) described from Oriental China.
