I think Cogger changed it from Rhinoplocephalus to Suta in 1992. As best I can ascertain it was reclassified as Parasuta somewhere around 2006 and this revision isonly slowly gaining acceptance. This particular species has been put into 6 different genera over time and this is its second time as Parasuta. The reason is that different taxonomists have place different relative importance on the features available to them. You also have those who tend to form few and larger groups (the 'lumpers') and those who tend to form many smaller groups (the 'splitters').
