Arbanitis michaeli is a species of armoured trap-door spider in the family Idiopidae, and is endemic to New South Wales.
It was first described by Graham Wishart in 2006 as Misgolas michaeli,[1] but was transferred to the genus, Arbanitis, by Michael Rix and others in 2017.[1]
The species epithet, michaeli, honours the Australian arachnologist, Michael Gray.
