It was first identified by Carl Henrik Boheman in 1858, under the name Nacerdes nigronotata.

Parisopalpus nigronotatus is generally coloured brick-red, with dark spots found on the beetle's body and legs.

[3] It was introduced to New Zealand in 1931,[4] and is found in Nelson and the North Island.

[4] Grubs of the species are typically found in rotting wood, and as adults the beetles feed on nectar and pollen, and are attracted to light.

[6] The beetles secrete a toxic substance as a defense, which causes skin blisters in humans if touched.
