Hello all, I have recently obtained a large number of Cameroon butterflies and working to spread them. As I tried to identify them, I realized Euphaedra was in quite chaotic situation. I have following references but sometimes information conflict with different images of the species. I don't know if this is because of individual variations, forms, bad photos, or simply error. Butterflies of West Africa (Larsen, 2005) Butterflies of the World, Part 4 (Hecq, 1999) Butterflies of the World, Part 48 (Faravel, 2020) Papillons du Gabon (Vande weghe, 2010) Euphaedra (Hecq, 1997) Butterflies of the Afrotropical Region, Part II (D'Abrera, 2004) - revised edition To confirm, I also checked Type specimens from the Africa Museum - what a great resource! (https://www.africamuseum.be/en/research/collections_libraries/biology/collections/lepidoptera/result_genus?genus_name=Euphaedra) Genus Euphaedra [Afrotropical Butterflies] (Williams, updated 7 Apr 2021) PDF file Obtaining Lambillionea copies to see the original description seems impossible. Even with many references, I failed to id them with confident... I thought about narrowing down the candidates by looking at the butterfly checklist on Wikipedia. This was somewhat helpful. Anyway, if I can get some expert review on my photo list so far, I really appreciate it!

The photo links don't seem to work, at least not for me. I get the following error message: This site can’t be reached The webpage at www.pteron-world.com/temp/Euphaedra-2.png might be temporarily down or it may have moved permanently to a new web address. Adam.

Hi Adam, thank you. I see the images fine from my PC and iPhone ok. Hmmm. I assume I cannnot "upload" the images.

I just noticed E. demeter male and female recto images are reversed.

koji <i>Euphaedra</i> are definitely a "chaotic" group. I would like to help, but frankly speaking the number of IDs you're asking for is daunting. Are you truly uncertain about every one of these? Or is there a particular specimen/species you'd like to start with?

Thank you cabintom. Sorry I listed obvious ones too like ruspina, medon, edwadsii, etc. The group I’m confused the most now are the xypete group and the margaritifera…

It looks as though this is another case of inability to open websites on my ancient computer, as I get the same error for the pteron-world homepage. Usually I get a different error message for websites I cannot access, not one that the page could not be found.

I too have found Euphaedra a nightmare to work through.
I have attempted to make my own Identification plates and keys working from all the sources you list and a few Lambillionea that I do have. I find that the existing plates in the books and revisions never show the upperside and underside of both male and female specimens together side by side. I got as far as the themis group in the subgenus Euphaedrana and then have not found time and energy to continue. Especially confusing are the preussi and eleus groups, I still have dozens of specimens still to be identified correctly.
If I can help I will but one at a time as I find this easier. I am not an expert only picking up what I have over many years of interest in African butterflies.

Hi Adam, what would be the best way to post the photos for you? I assume I cannot upload directly. If it’s ok, I will create another thread but this time limit the number of specimens.
Thank you,

Koji,
Please don't worry about sending me the photos, I would have absolutely no idea what species they are as they are way outside my field. I originally thought that possibly no-one else could see the photos, hence my comment.
Good to see you on the ICF, by the way.
Adam.

17. E. xypete Male : yes Female : I feel this is more likely to be E. hebes. Dorsally it agrees very well with the female figured in Hecq (2007). Very flat, elongated marking in 4 stretched along the nerve, smudge in 2. Ventrally yours has bolder black markings that it should though. That said, I feel the general disposition of the marking line up well with E. hebes, while the HW "eyebrows" aren't thin and stretched out as in E. xypete.
18. E. hewitsoni All seem right.
20. E. acuta Male : yes Female : Maybe? It's a very good match with the MRAC "allotype" specimen for E. acuta, but Hecq specifies that ventrally the FW band should be interiorly bordered by thick black markings (as in your male).
21. E. maxima. No, I don't believe so. The sub-apical band isn't the right shape or colour for maxima. It's close to your female "E. acuta", so I'm inclined to place them together. That said, I'm not comfortable saying it is E. acuta... and am tempted towards E. oremansi, but that species has only been known from Gabon & DRC (apparently no records from the Rep. Congo, which lies inbetween).
24. E. karschi Yes.
25. E. pervaga Yes.
26. E. hollandi Yes, but the valid name is E. diffusa.
27. E. diffusa Yes.
28. E. ansorgei Yes.

cabintom Thank you! E. hollandi = diffusa makes a lot of sense. I was wondering if these are same species. I also leant that piriformis = sardetta. That also made sense as well !

For up to date nomenclature metamorphosis.org.za/?p=articles&s=List&pt=166 is very helpful. Don't rely on the figures for identification though. It's a work in progress and some of the Euphaedra are doubtfully placed. I'm still planning on working through your ravola group specimens, with the working assumption that you have a few different species lumped into margaritifera.

cabintom Thank you. Yes I placed some on unknowns in margaritifera. I maybe able to get help on DNA of these. So once I have good identification of these specimens, DNA will be inspected. It will be very interesting to see the result.
