" Chamalycaeus " panshiensis - Pall-Gergely et al. 2017 : 107. Type locality. "Hongn-an forestry centre, Panshi County ( 43°15'N , 126°10'E ), Jilin Province, China". Material examined. Type specimen presumably lost. Remarks. The type specimens could not be found in Beijing during a recent search, and they are thus considered lost. The original description is not sufficient for correct generic placement. A Dicharax species have been collected near the type locality of C. panshiensis (Guoyi Zhang pers. comm.) reminiscent of Korean and Japanese Dicharax species, which suggests that C. panshiensis belongs to the genus Dicharax . However, since no specimens are available and the original description is also useless, collection of topotypic specimens would be necessary.
