Remarks. Although the type specimen of Cantharis confossicollis was attached with Wittmer's manuscript label " Athem ellus confossicollis (Fairm.)", it has never been published formally for this taxonomic change. In our opinion, this speciesis definitely a member of Lycocerus due to the following characters: pronotum subquadrate, all tarsal claws simple and the aedeagus with dorsal plates of parameres separated. At the same time, Lycocerus multiimpressus (Wittmer, 1997) is considered to be a junior synonym of Lycocerus confossicollis (Fairmaire, 1891), comb. n., since we could not find differences between both nominal species in their morphological characters, including appearance and aedeagus. Therefore, we suggest Lycocerus multiimpressus is a new subjective synonym of Lycocerus confossicollis . Figures 10-15.
