A weevil by another name

The notable weevil that lives on viper's bugloss has recently changed from Ceuthorhynchus geographicus to Mogulones geographicus. It doesn't have a common name, but the viper's bugloss weevil would be sensible. The NBN Gatewayfor this species shows the national distribution as being just 27 10km squares. It is one of the species being considered for biological control of purple viper's bugloss in Australia, where the plant is not native and is referred to as Patterson's curse.

At 3mm this image gives an idea of scale...

So are there any other similar looking weevils that could be found on this plant that might be confused with this species?

'cannot possibly be mistaken for any other' (Fowler, 1891, The Coleoptera of the British Isles).

This species is very distinctive, although Mogulones asperifoliarum also occurs on viper's bugloss and is black with white scales but is smaller and doesn't have the scales arranged in distinctive white lines as in geographicus.
