Remarks.

Based on the examination of the types of Lycocerus obscurus Pic, 1916 and some additional material at our disposal, we found no difference between it and Lycocerus rubroniger Švihla, 2011, which was presented with an adequate photo of the habitus and illustrations of aedeagus in the original publication. Therefore, Lycocerus rubroniger is synonymized with Lycocerus obscurus here, and provided with the supplementary description and illustration of abdominal sternite VIII of female.
