The species is named for Lucius Malfoy, a character in the fictional Harry Potter series of books by J.K. Rowling,[1][2] although the genus was described in 1903.

Its coloration pattern, as well as its geographic range, distinguish it from other species in the genus.

Specimens were collected by malaise trap in spring to late summer (September through to March) in a wide range of habitats, in or near Nothofagus forests and other native forests and brush, from close to sea level up to 850 m.[3] However very few specimens were collected from any one area, so the species appears to be naturally uncommon.

It is the only member of the genus Lusius so far described from Australasia, though this may represent a lack of sampling.

They chose the name in order to "redeem the reputation of wasps" in a manner similar to the redemption of Lucius Malfoy's character in the Harry Potter series.
