the describers of "nhandumirim" tested its relations using two phylogenetic analyses focused around the origin of dinosaurs. the first one, created previously by cabreira "et al." (2016), considered it the most basal theropod, as the sister taxon to neotheropods. this is supported by a wide ischiadic peduncle and several traits of the tibia. the cabreira "et al." (2016) analysis is notable for excluding several other traditional basal theropods from the group. these include "daemonosaurus", "tawa", "chindesaurus", and "eodromaeus", which are considered basal saurischians according to their results.
