Delias wollastoni is a rare butterfly of central New Guinea. A new subspecies has recently been found in the Weyland Mountains. This Fabulous butterfly was discovered by A.F. R. Wollaston on Castensz in 1913 and later during 1938 L. J. Toxopeus [ Archibold expedition ] collected the butterfly near Lake Habbema which was described by Roepke as ssp bryophila in 1955. Bernard d, Abrera  treated ssp bryophila and a synonym of the nominate race. I have been able view a good number of male specimens of D. wollastoni wollastoni and bryophila and they are indeed close. The main difference seems to the amount of black markings on the uppersides which is in bryophila seems to be quite black and not blackish brown as in wollastoni. Below are some specimens in my collection of both subspecies and the recto type male [ BMNH].

Delias wollastoni bryophila from Tiom, Air Garam, Baliem Valley. July 1990 Quite marked but shown because of its locality, better specimen of the verso of this subspecies from other Baliem localities may be found in at the start of this thread.

FYI it is "Air Garam", it means "Salt water" in Indonesian.
It is a wonderful place near Kurulu village (called Jiwika in Indonesian). Papuan women use palm leaves to collect the salt in this place... As you can imagine salt is very rare in those mountains ! Papuans seems to "worship" this place, it may explain why it is not deforested while all surounding places are.
In Kurulu village, there is an impressive mummy that locals show to the rare tourists.
Delias klossi is with out doubt one of my favourite Delias species and is a real beauty. A male of this species was first taken by Cecil Boden Kloss on Carstensz during the 1912-1913 Wollaston expedition. It was named in his honour by Lord Walter Rothschild in 1915 who was very pleased with the new Delias. During the 1938 Archbold expedition the Dutch entomologist L. J. Toxopeus took further specimens of D. klossi on Mount Wilhelmia and the Baliem Valley area which were named as subspecies chrysanthemum by Roepke in 1955. Specimens from the Ilu-Mulia area were named as ssp gome by Van Mastrigt in 2000. Shown below is the type male of Delias Klossi [BMNH] and a specimen each of ssp chrysanthemum and gome that have been added to my collection. I hope that Delias enthusiasts will enjoy these.

Delias elongatus is a fairly rare butterfly of the Arfak Mountains where it was discovered by the Pratt brothers in 1909. This species was described from a single male by Sir George Kenrick in 1911 and A. E. Pratt and sons took a further series of three males and three females in 1914 for J.J. Joicey . Shown below are two male specimens from my collection and the plate showing the type male of D. elongatus  with Delias africanus = albertisi  and the new Delias imitator  which were also collected by the Pratts. The Ornithoptera tithonus was later described as subspecies misresiana by Joicey and Noakes in 1915.
Any members Delias specimens from New Guinea or its Islands or interesting information on any species would be most welcome here.
Delias autumnalis is I believe a uncommon species of the Clathrata group. This gorgeous butterfly was first captured by L. J. Toxopeus who discovered a number of new Delias during the Archbold 1938/1939 expedition to Central New Guinea.

Delias carstensziana from the Eichorni group was discovered at High Altitude on Mount Carstensz by Sandy Wollaston in Feb/March 1913 and described by Rothschild in 1915. Two specimens also from high altitude on Mount Carstensz are shown below and exhibit a interesting variation in markings. This used to be considered a rare species but perhaps not so now?
I hope some members will have enjoyed seeing some of my favourite Delias species from New Guinea. It would be nice see other members favourite Delias specimens from this area. Peter
There is a brand new article in the Nachrichten des Entomologischen Vereins Apollo, Jg. 34, Heft 1/2, July 2013, p. 17-27, colour plates, with the title "The Delias Hübner, 1819 of the Bismarck Archipelago, Papua New Guinea, with description of a new species from New Britain Island (Lepidoptera, Pieridae)" by Chris J. Müller and Laurie Wills.
The Island of Biak near the North coast of New Guinea certainly has some fabulous Delias species, most of which were discovered by Charles and Felix Pratt with younger brother Joseph in June 1914. Here are four specimens of the very rare Delias talboti [Joicey & Noakes 1915] that were collected by them on Biak. They were presented to OUNHM collection by James John Joicey of the private Hill museum in a bequest of 1938. Three are listed as co-types = paratypes?
Cotype is an obsolete term which has no standing in The Code, but in the past it was used a lot by the likes of Bang-Haas. They could be either syntypes or paratypes depending on whether a holotype was designated. I don't know the species but the chances are that if it was described in the early 20th century, they would be syntypes as not many people bothered with holotypes in those days.
Thank Bob. I listed the D. talboti as co types because that is how they are presented in the drawer by the Hope staff who arranged them. All the other types of this rare butterfly were given by Joicey to the BMNH and which I have yet to see. The Pratts were very fortunate to collect a series. Peter.
Here is the plate that accompanied the original description of Delias talboti by Joicey and Noakes showing specimens collected by the Pratts. From the Transactions of the Entomological Society of London 1915. Superb paintings.
Delias luctuosa is a quite a large and very beautiful species from New Guinea. The butterfly was originally described as a subspecies of D. iltis by Jordan in 1912 from a male specimen captured at 11,000 feet on Mount Groome in Papua New Guinea. The type specimen was given to A.S. Meek by a friend.

I'm glad you mount your Delias with the ventral side facing upwards. Last week I saw the saddest Delias collection ever, several hundred specimen all mounted with dorsal side facing upwards. White, white, a little bit of black and more white
