Deep Brown Dart.

This is probably the result of a taxonomic fudge. Following DNA analysis, both of these are now considered to be the same species. The scientific name that takes priority is Aporophyla lueneburgensis, which was called Northern Deep Brown Dart. However, as the only species now it has now been re-assigned the name Deep Brown Dart.

As a result, anything you submit as Deep Brown Dart should now map across to Aporophyla lueneburgensis, but it might show up as Northern Deep Brown Dart due to the previous name association.

I had the same thoughts as Steve. It would help if all occurrences of these species are relabelled as Deep Brown / Northern Deep Brown Dart to avoid confusion.
