Col. 1 contains d. sulphurea from Bioko; the specimens are in poor condition, especially the females, but are impossible to obtain anymore. These were collected by Canu in the 1980s. Col. 2 #1-2 are d. ochraceana, restricted to two Kenyan mountains. The remainder of Col. 2 plus Col. 3 are d. flavicornis, restricted to Mt Kulal in Kenya; they're the same in pattern as ochraceana, but most interestingly have golden-yellow antennae, unlike all other ssp. The last 2 columns are males of d. polytrophus from the highlands of Central Kenya.

Hi Andrew - Thanks for your comments and kind words! And of course you are more than welcome to resurrect any old threads that interest you.
I haven't seen many ochraceana specimens - the pair shown here, plus a small series (3 M + 2 ochreous F) in a friend's collection are all that I've seen. I've just had another look at my photo of the latter, and I don't see that male ochraceana can be consistently separated from polytrophus since they lack the distinctive orange-yellow antennae of flavicornis. Males of the latter also frequently have prominent yellow spots within the FW black area, as you see in my third male; my ochracea male has a much diminished version of that, but the 3 specimens in my friend's collection have no yellow spots at all.
The females of the two Kenyan endemic species are distinct and easy to separate from all others. Of course those of flavicornis have orange-yellow antennae, while those of ochraceana are black. However, the females' HW submarginal spots have a shape that differs from others; I think of them as being shaped like deer tracks, especially in flavicornis. Female ochraceana also occurs in a white ("hippocoonides") form, but it's quite rare; neither my friend nor I have one. The third flavicornis female form ("speciosa") is not known in ochraceana.
The females of the two Kenyan endemic species are distinct and easy to separate from all others...the females' HW submarginal spots have a shape that differs from others; I think of them as being shaped like deer tracks, especially in flavicornis.
I hope this is helpful!
Is this what you mean? kind of wedge-shaped HW spots in opposing pairs...?
Blesséd is he who expects nothing...for he shall not be disappointed.
Sorry but this is a hasty response to the above latest conversation. This drawer contains the above subspecies including columns 5 and 6 which I believe are ssp: ochaceana these have been bred by Sir Cyril Clarke. Please note that they are still labelled as ssp: ochracea as this was done before the name update. I hope it is self-explanatory but will check out other points if needed as it is a couple of years since I did the drawer.
Great collection Danny Again, I am afraid to see a so interesting group without any consistent systematic. as for many others in Africa such as phorcas, nireus, etc..... One had been afraid in the past to study them because of great polyphormism but today genetic can help to solve main problems, espacially in this genus where it seems to works vey well.
s'il n'y pas de solution c'est qu'il n'y a pas de problème ! akuna matata ....
