So the new species name belongs to ' biokoensis' from mainland Africa, and true biokoensis is restricted to the island race. The English in the abstract is unclear, because use of the word 'mixed' in the context implies that they occur together. Please can you confirm the exact publication date for the record, thank you. Adam. yes they occur together in collection (they are mixed in collection) ...

The abstract of the new paper has just been posted on ResearchGate by Dr. Cipolla, and I have requested a copy of the paper. Here is the text of the abstract as posted: Résumé. Une nouvelle espèce de Papilionidae du genre Graphium Scopoli, 1777 est décrite de République démocratique du Congo, Graphium bouyeri n. sp. La nouvelle espèce était précédemment confondue avec Graphium biokoensis Gauthier, 1984. Graphium bouyeri n. sp. est présente dans tout le bloc forestier équatorial d’Afrique centrale du Nigeria jusqu’à l’est de la République démocratique du Congo. Summary. A new Papilionidae species of the genus Graphium Scopoli, 1777 is described from Democratic Republic of Congo, Graphium bouyeri n. sp. The new species was previously mixed with Graphium biokoensis Gauthier, 1984. Graphium bouyeri n. sp. occurs in the all equatorial forest from Nigeria to the east of the Democratic Republic of Congo. Keywords. Lepidoptera, Papilionidae, Graphium, Bioko, Cameroon, Democratic Republic of Congo, Nigeria, nova species. Congratulations to africaone for having a new species named after him! I look forward to seeing the information in this paper in order to distinguish Graphium biokoensis and the new species, Graphium bouyeri. Adam. Graphium biokoensis has been misinterpreted, it is really something near policenes (Gauthier well interpreted this). It is localised on Bioko island where it seems to replace policenes (to be verified but none information against until now, despite some unverifiable assertions ... as usual). Unfortunetely, none fresh biokoensis has been available for barcode despite a very big series has been caught in the past (without any "true" policenes). As it is often the case for islander population, it is more constant than the continental ones. The new one (not existing on Bioko) is closer to liponesco (a small dark, long tailed, forest Graphium of the policenes group localised in Western Africa) from which it is easily distinguised by other characters as the small white dots on HW well pointed by Larsen. Note that specimen of the species from western part (ie Cameroon) is more marked than the eastern one (ie Kivu), those of intermediate regions (as specimen represented here) being intermediate in pattern. Some specimens from Kivu Mountains are clearly difficult (but possible) to distinguish from some dark small policenes. Barcode (not included in the paper) confirms the distinction and external characters. Waiting further information to publish first instars and barcode results. Unfortuneley, it is a poorly collected spcies as it is confused with policenes than nobody collect.

a new African Graphium .... www.entomoafricana.org/pdf will be soon (1-2 days) available on Researchgate (on request) on Alexandre Cipolla account.

it is what I first believed but all specimens from that locality even of the wet season have large and light green bands but sure that dry season specimens are lighter

I recently got some fresh policenes from Katanga that strangely look like telloi. telloi has been described from the northern hemisphre and katanga is in the southern one with the forest between them. Then ssp status seems inadequate. the problem is that telloi is quite distinct and no genetic difference (barcode) occurs. Another problem with this group among some others.

thanks Adam, I believe it is more a lack of red (genetically) than a "replacement" color. This lack also exist in Saturniidae in which ground color became yellowish instead of brown/orange or the red/pink ocelli rings.

Does exist form name (or aberrant) for Graphium that have the red of the verso replaced by brown as showed on the following picture for G. policenes ? I know such form existing also in angolanus, fulleri and antheus

Many thanks for the determination. The pictured specimen has a size of 51 mm. (Sorry, I forgot to mention this) Seems to be a giant. Andreas how do you count the mesure ? head to tip elytra ? including antennas ? 51 mm is abnormal size if you mesure from head to tip elytra ... 35 mm is a normal big specimen

i think because this is not a top African Graphium

by browsing these texts I realize that the ssp dufranei of graphium almansor (collins & larsen 2008 )has not been mentioned which texts ?

this seems not an aberrant look ...

As far as I know, most of the commercial breeders exporting pupae out of tropical Africa are in Kenya or Tanzania, so it is likely that the stock originated somewhere there, but it is equally likely that the livestock did not come from a single locality. There are also breeders in southern Africa, and live material can be mixed from different places and bred together. Commercial butterfly farms in the Philippines exchange live pupae across different parts of the archipelago and mix them all together to reduce the possibility of inbreeding. As a result it is very difficult to assign a geographical origin to commercially farmed material, unless the origin of the stock is known and communicated by the breeders and sellers. Adam. a nightmare as dardanus covers a complex of species not yet solved ....
