My list (as opposed to this one) includes Fea's/Desertas Petrel and Bramble agg. Aggregates in general: At the time of writing I cannot do gen. det. The records I send therefore include eg. November Moth agg. My approach for this list has been to allocate the record to the most likely congener based on: external features, reference to the literature, expert advice and the relative abundance in the particular location and habitat. I obviously would not include more than one member of any such group unless and until I have positively identified both.
