Hi Olivier. Thank you. There is no collectors name on the data label, just Pass Valley, 03/01/1995. I believe that since its discovery at Abmisibil, Delias wollastoni abmisibilensis has been found in further localities in West Papua, such as Pass Valley, Korupun and Ok Tedi, according to one web source.
Interesting, I didn't know that wollastoni abmisibilensis reaches the Pass Valley. Strange as I heard some ssp bryophila were found there... and abmisibilensis is very rare on the market while the Pass Valley is "often" prospected.
I guess the Pass Valley is the "border" between the 2 ssp, so it may depend from one collecting spot to another inside the Pass Valley.
I think the locality is probably correct, as it came from a collector in England, who has one of the biggest world Delias collections, and is very knowledgeable, he started collecting in the 1970s, and has been to New Guinea, and collected with the late Mastright, in several places in the highlands. He has received much material from Henk, but is a "very private collector" who does not usually sell or exchange. He had just as rare/rarer goodies, including females, but a well known vendor/collector had already snapped many of these these up before the show opened, as his prices were very reasonable indeed. He had several paratypes of West New Guinea species from the original collections by Mastright for sale, but my pocket is ever shallow at the present. His two tables of well set Delias at the show were a glory to behold , and I had a very interesting chat with him, about his collecting expeditions with Mastright, the difficulties of collecting in New Guinea etc, and saw photos of his magnificent collections, and several images of drawers containing New Guinea rarities were amazing. Some drawers contained very long series of much sought after Delias. A good experience for a Delias collector, to re-kindle the ever burning flame brighter.
