Thanks for the links Tom, to these great articles. It seems there are a lot more probable extinct African butterflies that I realized.
Peter.

Mimoides lysithous f harrisianus from Brazil could be next, down to one small shrinking colony.

That's a good point dunc, I wonder how many other butterflies and other moths species are facing extinction. I wonder what the next extinctions are likely to be.

I would imagine those that are most set in their evolutionary ways with fickle life histories who's habitat has shrunk to next to nothing and are left with nowhere else to go, there are more than a few candidates.

The extinction of two species of Fijian Zygaenidae by Biocontrol. Two small species of Zygaenidae endemics, the serious pest Levuana iridescens and the harmless Heteropan dolens were eradicated by professional entomologists using biocontrol. Coconut Plantations were the main economy of the native peoples of the Fijian Islands in the late 1800s to early 1900s. From around 1877, coconut plantations on Viti Levu were severely affected by Levuana iridescens (Bethune Baker), a small purple moth,whose larvae trenched the underside of the leaves and the Palms died. Chemical spraying failed. In 1925 entomologists imported and released a parasitic fly- Bessa remota ( Aldrich) on the island of Viti Levu. This provided immediate control of the moth, eventually leading to its extinction on that Island. Levuana iridescens it has not be seen since the 1950s. The parasitic flies also preyed upon the larvae of the pretty and harmless Fiji Viti Levu endemic, Heteropan dolens and is now thought to be extinct. Repeated searches over many years have failed to find any extant population. Howarth wrote that H. dolens was extinct by 1929. The only specimen of Heteropan dolens in the collections of the O.U.M.N.H. Heteropan dolens. Painting from Herbert Druce, ' List of Lepidoptera - Herocera collected by Mr. C. M. Woodford at Suva, Viti Levu, Fiji Islands, with the ' Descriptions of some new species '. Proceedings of the Zoological Society of London 219-231. 1888. Levuana iridescens.

one must be careful . The case of Erikssonia (in RSA). The specimens from RSA were first determinated as E. acreaina and after recognised as a good species E. edgei. Then we are speaking about E. edgei (as acreaina in first time), an endemic species in RSA (the true acreaina occurs in Angola, Zambia and possibly Congo) It was suspect to be extinct but recently they discovered a new population. If the island cases are quite "easy" to establish, on continent it is not so easy especially with seasonal and / or myrmecophilic species.

Yes he is rather good at obtaining special species.

There was no image of the specimen? Is this the chap from Canada. He has a stall at Juvisy full of good things. I have bought a few Delias from him.
