africaone If that was the case I'd have a lot more specimens. I wish I knew the foodplant. One was caught flying up the rift escarpment. Pure luck on my part with the overhead swing. The second was feeding at Tridax (I think), in an area of cow pasture which has very little variety in terms of plants. do you have forest near there, a gallery forest ? Unusual to se females far from the foodplant. Did you record the hour of catching ?

The female of P. echerioides nioka is significantly different than that of joiceyi, looking closer to plagiatus than anything. In my opinion, it's clear that it is something else, but what? That's tricky. In Berger's Papillons du Zaire (1981) he mentions having seen a (1) male of the "? sous-espèce nioka", who's discal band is thinner than the other subspecies in the area. That's the only male I'm aware of. I've collected 2 females myself (and they're the only examples of the species I've seen here to date). I only know of 3 or 4 other females having been collected. It's a strange ratio because, as Thierry mentioned, usually females are much harder to find. it is because you probably hunt near the foodplant.

I'm curious as to thoughts on Papilio echerioides nioka? I believe it's one of the rarest African subspecies. at ssp level and sex rarity (female), there are probably many more, count also the uncertified descriptions and those concealed in groups that needs revision.

Papilio chitondensis (nireus group)- recently rediscovered in a specific difficult plateau locality in Angola by Thierry Bouyer, only 12 specimens incl 4 females returned. All in specialist collections. 2 females only not 4G. gudenusi females (I was led to believe that for a long time Steve Collins had the only one known). Many females has been caught for this last 15 years (from Ruanda and RDC)
olbrechtsi / One of the mythic species (I caught one in the 1980ies and believe it is the last known)aurivilliusi / THE MYTHIC species (only known by the small type series)/abri : only knwon by 2 males (may be more but not recorded)

200-300 pages for each small islands .... how much for the continent ? pages and books ? and what budget you will spend for all the world collection ? Is there any" good price" for those that subcript for the all collection ? if he doesn't sell some at the beginnings, the project will stop quickly.

not marlieri, the genus is in need of a revision.

Just having a more in deep look in Angolense book for the "nireus group". It is unclear and confirms necessity to revise this group. For chitondensis they confirm the very strict localisation and endemism (I really have been lucky to catch it ). they just illustrate a PT.

I just had a quick look at the Code (articles 74 and 75) and there is no clause in the Code that covers this case. Also there are only time related clauses for neotype designations made before 1961. I will seek further advice and report here when I have more information. Adam. that waht I believed .. thanks for verification Adam. Like I said, a neotype is to be designated in case of necessity.

If Bivar de Souza designated a "lectotype" from one of the paratypes in his collection after the loss of the holotype, that specimen is indeed the neotype. Adam. wrong designation of a lectotype interpreted as the designation of a neotype. Is that a rule of the Code ?

Just receiving the book "Butterflies of Angola vol 1". Interesting despite "old school" and strange distribution maps. The treatment of nireus group of Angola is included in.

4. P. chitondensis - Thierry and Steve between them have neotype, several males and a couple of female(s). Barcoding would be really helpful here. The HOLOTYPE of Papilio chitondensis, originally described as a subspecies of P. bromius, is housed in Museu Bocage, Portugal. Thierry Bouyer "designated" a "neallotype" from a female collected in 1998, but that has absolutely no type status whatsoever. I assume that the above comment "neotype" actually refers to the "neallotype". Adam. here is the exact text I wrote in the paper (p. 13) "BIVAR DE SOUSA et FERNANDES l’avaient d’abord signalée en 1964 sous le nom de bromius en s’interrogeant sur sa parenté avec chrapkowskii Suffert, 1904. Ensuite, elle a été décrite par BIVAR DE SOUSA et FERNANDES en 1966 comme sous-espèce de bromius. Enfin, BIVAR DE SOUSA l’a finalement élevée au rang d’espèce en 1983. La série typique comportait 6 mâles, l’holotype et deux paratypes dans le collection du Museu Bocage et trois mâles dans la collection Bivar de Sousa. Suite à la destruction de la collection du Museu Bocage, BIVAR DE SOUSA a désigné en 1983 un lectotype choisi parmi les paratypes de sa collection et signale la présence de 3 paratypes dans sa collection (?). Il aurait dû en fait nommer un néotype et non un lectotype puisque l’holotype était détruit. " In fact Bivar de Souza designed a lectotype in place of a neotype (as the holotype was detroyed), this must be corrected officially if there is a need of a neotype. On the type series (6 males), it seems that only the 3 paratypes males in Bivar de Souza's collection exist today. Ironic to see that this time a private collection helped to preserve types of a rare sp (holotype housed and destroyed in an official Museum) I designed a female neallotype that has no nomenclatural value (even the term neallotype has no value).
