Notes on the new synonymy. The original description of Paederus symmetricus Li, Zhou & Solodovnikov, 2013 is based on only two specimens, both with the aedeagus suboptimally prepared, so that the internal sac was not clearly seen. The newly received material allowed a more detailed study of the aedeagus and revealed its identity with the aedeagus of P. parvidenticulatus Li et al., 2013 . Based on that, as well as the shape of labrum, male sternites VII and VIII, and female sternites VIII and IX, all these structures identical in both species, there is no doubt that P. symmetricus Li et al., 2013 and P. parvidenticulatus Li et al., 2013 are conspecific. Thus, the synonymy is proposed.
