Taxonomical notes on some fossil soldier beetles (Cantharidae)

In this document I describe the oldest fossil taxon of soldier beetles: †Chauliognathus koonwarra sp. nov. known so far, from the Lower Cretaceous of Australia. I also set up the new fossil tribe †Nothotytthonychini tr. nov. for to accomodate the genus †Nothotytthonyx. Furthermore, the fossil taxa †Lithocantharis lunglokshuiensis Lin in Lin & Lee, 1997 and †Wongyekokia angustris Lin in Lin & Lee, 1997 are transferred from the family Cantharidae to the family Carabidae new placements, and †Podabrus santaritensis Cockerell, 1936 is still considered an available name and a representative of the family Cantharidae. †Electronycha prussica Kazantsev, 2013 and †Michalskantharis bursztynica Fanti, 2017 are considered as part of the tribe Cacomorphocerini new placements.
