A previously overlooked difference between the blesbok and the bontebok: pale vs dark tail-tassel

@michalsloviak @geichhorn @colin25 @tandala @dewald2 @simontonge @tonyrebelo @jeremygilmore

The blesbok (Damaliscus pygargus phillipsi) differs from the bontebok (Damaliscus pygargus pygargus) in having a pale distal section to the tail-tassel (https://www.alamy.com/blesbok-damaliscus-pygargus-phillipsi-an-antelope-endemic-to-south-africa-and-swaziland-grazing-in-grassland-image344938371.html).

This difference has not, as far as I know, been noticed by any naturalist or zoologist.

The tail-tassel of both subspecies of Damaliscus pygargus, when intact, reaches to below the hock.

In the bontebok, the whole tail-tassel is always dark (https://www.dreamstime.com/stock-image-bontebok-antelope-image14126791 and https://www.dreamstime.com/royalty-free-stock-photo-bontebok-antelope-image4517985 and https://www.dreamstime.com/royalty-free-stock-image-bontebok-antelope-image20532746 and https://stock.adobe.com/search?k=damaliscus&asset_id=22456309).

However, in the blesbok, the distal part of the tail-tassel tends to be pale:
