Arnoldius scissor was described by Crawley (1922) based on two queens. The peculiar character of the queen mandible (with its reduced dentition and sharp, curved, concave inner edge) strongly supports the notion that the queen is a social parasite. The queens were collected from a colony of Iridomyrmex innocens, and Crawley was of the opinion that this species was parasitic on I. innocens. (Heterick, 2009)
