A new soldier beetle of the extinct tribe Cacomorphocerini Fanti Kupryjanowicz, 2018

摘要

A new fossil Cacomorphocerus Schaufuss, 1892 from Baltic amber, i.e., Cacomorphocerus coleae sp. nov. is described. Related to C. eocenicus Bukejs, Fanti McKellar, 2019, the new species is characterized by 12 antennomeres that are little modified, with antennomere VI saucer-shaped and asymmetrical, antennomere V enlarged and antennomeres VII and VIII squarish and sub-rectangular. The slightly modified antennae of some species of Cacomorphocerus confirm a relationship with the genus Sucinorhagonycha Kuska, 1996. Therefore, given the synapomorphy of the antennae, Sucinorhagonycha is transferred from the tribe Cantharini Imhoff, 1856 to Cacomorphocerini Fanti Kupryjanowicz, 2018 (new placement).
