Of or relating to the Cantharidae family of beetles or to cantharidin and its properties.
From 'Cantharidae' (the beetle family) plus the suffix '-ean' meaning 'of or relating to.' Formed in modern zoological and biological terminology.
The cantharidean beetles are masters of chemical warfare—they don't actually inject venom like snakes; instead, they secrete cantharidin through their joints as a 'chemical smoke bomb' defense!
