If true, that's quite amazing. However, I'd immediately have to question its provenance and whether the data is indeed correct...iphitas is well known as being extinct, and it seems that news would have been widespread if it had been rediscovered, even decades ago. It seems that Jacques E. iphitas specimen has the data locality Vitoria, Brazil which lies on the Atlantic coast 521km north of Rio de Janeiro. He has kindly sent this further image of his splendid rarity with three ssp of Eurytides dolican. You can clearly see the date 1977 on the accompanying data and in Jacques opinion it is not extinct. He mentions that the specimen came in a large lot bought at a Drouot Paris sale.

Traditionally for birds and other larger animals, it's been 50 years after last sighting. I'd assume that this is also true for invertebrates, although it seems reasonable to be less for some that may have been restricted to a small area now known to be gone, for example.

Thanks for the further info, Peter. That would be great if true, but I remain highly skeptical of a single-specimen record.

Yes, the female is unknown. Its close relative, E. dolicaon, has females that tend to be more yellowish, making one wonder whether iphitas females were even more yellow than the males.

Peter This is NOT the type of Eurytides iphitas Hübner, 1821. It is that species, but is the type of form enervulata Fruhstorfer, 1907. Adam.

Adam, if this is not the male holotype, where is it.

Where are any of the Hübner types? I am not sure but I think that they no longer exist. The types of Hübner names are the specimens illustrated in his work (note that the illustrations are not the types, they just represent the appearance of the type specimens). Here is Hübner's illustration of Eurytides iphitas: Adam.

Thanks Adam for the information and nice plate, do you think there is any chance that this species still exists, what do you make of Jacques date of 1977 on his specimen of E. iphitas.

I would be inclined to believe the data on Jacques Porteneuve's specimen. It is quite probable that Eurytides iphitas may well be happily alive in Atlantic coast Brazil. The restrictions on collecting in Brazil actually are an impediment to our knowledge of the Brazilian butterflies, and there is a lot that could be learnt in that vast country.
Adam.

Deloneura immaculata - The Mbashe River Buff is a possibly extinct species of butterfly in the Lycaenidae family. It is assumed to be (or to have been) endemic to the densely forested Mbhashe River area of the Eastern Cape, South Africa. Searches subsequent to it's discovery however failed to yield any trace of it. Only three female specimens have ever been collected, all by Colonel Bowker, in 1863-64. The specimens are held in the South African Museum in Cape Town, and the Natural History Museum in London. ( text taken from Wiki ) But I have some chats with people in S.A and they told me that the area is hard to explore and it's always exist possibility that species is not extinct but very rare and hard to spot/collect ( save habitat - not singular species - putting more and more species on the red list, will not save them at all, if they will not find place to live ) Attachments:

Thank you for sharing tiass. I did not know that rare Deleneura immaculata !
Of course, we need to save habitats if we want to save biodiversity. Modern humanity = parasitism
