Aradus shermani was described by Heidemann in 1907. The Aradus is one of the most -rich genera in the , with species distributed across the Holarctic region and numerous fossil species known from Baltic amber .
Fossil relatives
While A. shermani itself is not known from the fossil record, the Aradus has exceptional fossil representation in Baltic amber, with 14 described from Eocene . These fossil species, including A. macrosomus, provide evidence that the genus has maintained similar ecological associations with dead wood for at least 45 million years.
