See title!  Caught 4/VI/2016 Nyankunde, Ituri (1°25'N, 30°02'E) 1250m (I'm leaning towards A. leucographa.) |

Having had only a quick look I tend to agree that A leucographa is the most likely. The hindwing black spotting tends to suggest this.

I have assembled a collage of similar specimens for comparison. The identification are mine and so please correct any mistakes but I hope it is helpful. The first column are females of Acraea endoscota. The second column are male A endoscota. The third column are male Acraea leucographa. The fourth column shows a further similar species for comparison. They are Acraea admatha with two males above two females. The sources of these specimens is quite varied, but several from Cameroon.I can give data for individual specimens if needed.

Awesome! Thanks for putting that together. It seems my specimen most resembles your top A. endoscota specimen. I see what you mean though about the HW spotting, looking at the specimens of A. endoscota on acraea.com, most have the reduced spotting of the bottom three male specimens you figured, while A. leucographa much more consistently has all of the spots expressed. The other difference I observed from looking at the images on acraea.com is that for A. leucographa the HW black margin seems to extend slightly into peaks along the veins, whereas with A. endoscota the opposite occurs with red extending into the black margin along the veins. I'm uncertain if that's a good/consistent feature for identification. acraea.com/php/photomin.php?index=leucographaacraea.com/php/photomin.php?index=endoscota |

I'm uncertain if that's a good/consistent feature for identification. It seems that in "Butterflies of the World; Part 39", Bernaud and his co-author(s) point to this being the defining characteristic. A. endoscota's HW margin is formed by a series of arches. ("La marge d' endoscota est en forme d'arcades, les taches marginales etant cerclees de noir.") Also, from looking at ABRI's specimens, it would seem that it is uncommon for endoscota to feature any amount of white of the recto HW. |
