I note the following quotedfrom Lepidoptera Butterfly House:- 'This is probably the same species as Opsitycha squalidella, and Barea dryocoetes is the junior synonym, so it wiil likely be known as Opsitycha squalidella in future. I;m not sure what the autority for this would be. I see no reference on the Australian Faunal Directory that O. squalidela and B. dryocoetes are synonyms. ''
