Remarks.

The specimens that we examined included topotypes that were collected at the same time as the type specimen of this species ( Qiu and Morse 2021). We found that the harpagones each had four apical processes, which is rare in Psychomyia , occurring only in P. polyacantha and P. imamiah . By comparing these specimens and published descriptions and figures of the male genitalia of these two species, we believe that the morphological characteristics of the two species overlap. The type locality of P. polyacantha is in the basin of the Fujiang River, and the Fujiang River flows into the Jialing River, and the paratypes of P. polyacantha and the holotype of P. imamiah are from the basin of the Dadu River, which merges into the Minjiang River. Both the Jialing and Minjiang rivers are tributaries of the Yangtze, and their upstream habitats are similar and geographically adjacent. In summary, we identify P. polyacantha as a synonym of P. imamiah .
