Unknown Uganda Euphaedra sp.

[Trehopr1]

Here I have a species of Euphaedra which could use
an I.D. Its a lovely chocolate-brown color overall with
little white tips at the apex of the forewings. Seems like
something of a standout species but, I sure can't find it !

Another I.D. much appreciated...

It appears to be Euphaedra losinga.

Wow, you nailed this one on the head livingplanet3 !


My sincere compliments on helping me with this one.
The Euphaedra group is regarded as a tough one to differentiate generally....

You have a good eye and have always been VERY good with identifications. Respect.

Many thanks again !

Looks like E. harpalyce to me... the FW subapical band comes much nearer to the margin in E. losinga (furthermore, it doesn't seem that losinga has been recorded from Uganda).

The two species are so very similar, and I assume that there is some degree of variability within each, but indeed, thanks for pointing out the above details. I'm by no means particularly familiar with this quite extensive genus.

Trehopr, can you post the ventral surface of your specimen?

livingplanet, what's the source of your images? (Do you have the data for the specimens?) Quite possible I'm wrong, but my gut says your top image is a male harpalyce, while the bottom is definitely a female harpalyce.

Indeed, cabintom I will get a ventral picture this afternoon
and post it later today.

As mentioned, these butterflies are "danged" numerous over
there AND varied so all is not always what it may seem....

Hmm... I should have recognized the female harpalyce as my own!

The male from the Field Museum is almost certainly misidentified. It's a typical E. harpalyce spatiosa male. In losinga, the ventral HW features a better developed/more contrasted and narrower white discal band.

For reference:

Here's a male of E. harpalyce spatiosa:

(note that losinga is not found in eastern DRC where this specimen was collected)

The male HT of E. losinga knoopi can be seen here: https://virtualcol.africamuseum.be/prov ... ects/20912
Note that ssp. knoopi is very probably a synonym of ssp. wardi.
And here's a box of losinga wardi: https://virtualcol.africamuseum.be/prov ... ects/10416

Hello Cabintom,

Here is that underside shot of whatever species this is....

Hope this clarifies this specimens status. Again, it is out
of Uganda.

definitely E. harpalyce spatiosa
