I have tried to enter a record for the Dipteran Sapromyza albiceps. This as far as I know is its correct name. It does not seem to be listed as it does not appear under the suggested names within this taxon. Can this be rectified? Note: it is a taxon in NBN Atlas.
I've just had a look by copying and pasting Sapromyza albiceps and it comes up OK for me to both add and search for, so it might have just been the website playing up slightly.
