Verity's Colias names were indeed a nightmare and we did have to check each one individually. Kudrna created a lot more confusion with his misinterpretation of many names. I'll email you a copy of our Verity appendix as I think it could be very useful for understanding Verity names in other groups.

Bob I thought that was the case, and am aware that Kudrna's interpretations were not always accurate. I would be very interested to see your interpretation of Colias names, and indeed that can provide a useful guide to the other Verity names, thank you. Adam.

Just uploaded another upperside full pic of the OP example of P. antimachus f. melanescens for anyone interested. Don't see many of them around, after all.

Just wondering if this specimen is yours or in a friend's collection. It certainly is a marvelous and unique specimen for the species....

Don't see many of them around, after all. You don't see that many aberrations around, such as ab melanescens unless they are made, and many full melanics have flooded the market in some species, especially Nymphalidae and you can have drawers full . As in this case, they are much rarer in nature. I guess P. antimachus early stages are yet to be discovered?

I guess P. antimachus early stages are yet to be discovered? Yes, as far as I know they are completely unknown, and the larval food plant hasn't yet been recorded either. Adam.

Just wondering if this specimen is yours or in a friend's collection. It certainly is a marvelous and unique specimen for the species.... Hahahaha I wish it were in my collection! (Though it would be a serious waste of scarce & good material if it squatted in mine). IMO it should be in a serious scientific-available collection where such uncommon natural variants are in abundance - for serious investigators to study at genetic (and *epigenetic*) level: variations are often said to be a very useful starting-point for pinpointing elements of genetic variability and allele studies investigating mutations, and also for looking at "variable regions" of chromosomes. For example, the dardanus mimetic female genetics; and, wrt human interventions, I was particularly impressed by the Sodium Tungstate studies in British/Palaearctic Nymphalid species, which produced effects similar to cold-shock treatment, because the effects of the metal salt on DNA transcription and protein expression are sufficiently understood that the results gave insight into probable mechanisms of Cold-Shock phenotype alteration. This P. antimachus f. melanescens image was sent to me for an opinion, because I have a longstanding interest in W. African Papilionidae, and because I used to have a good memory (alas, tempus fugit). The owner (NOT me - honestly) is looking to sell, actually. Surprisingly. I understand it will be auctioned or advertised imminently somewhere, FWIW. Philatelists vs scientists......?

The foodplant of P. antimachus is highly likely to be one or more of the cardenolide-producing species in tropical West and Central Africa. The imago contains a high concentration of so-far unidentified cardenolides (Miriam Rothschild, 1970), which may be concentrated and retained from larval ingestion [and/or may be selectively sequestered from feeding habit]. Doesn't narrow it down much, sadly, until we know more details about the exact cardenolides present in the butterfly. Another study waiting to fall off a log!!

I noticed that the aforesaid P. antimachus f. [ab.] melanescens sold a few days ago for €1000 to a single bidder.
