ACKNOWLEDGMENTS

I am sincerely thankful to Dr Claire Villemant (MNHN, Paris, France) for the possibility to examine the material and her valuable help, to Dr Cornelis van Achterberg (Leiden, the Netherlands) and Dr Francisco Javier Peris-Felipo (Basel, Switzerland) for the constructive comments of the manuscript. This work was partly supported by the Russian Foundation for Basic Research (projects No. 16-04-00197) and the Russian State Research Project No. 01201351189. The material was collected within the framework of “Our Planet Reviewed Papua New Guinea 2012-2013” led by Pro-Natura International, the Muséum national d’Histoire naturelle (MNHN, France), the “Institut de Recherche pour le Développement” (IRD, France) in partnership with the “Institut Royal des Sciences Naturelles de Belgique ”, the New Guinea Binatang Research Center, the University of Papua New Guinea, and the Divine Word University of Madang. The program was funded by Prince Albert II of Monaco Foundation, Stavros Niarchos Foundation, Total Foundation, Fondation d’entreprise EDF, Fonds Pacifique, Reef Foundation, Spiecapag, Insect trapping and collection was performed by villagers from Wanang and Mt Wilhelm’s villages and sorting was done by the staff of the Binatang Research Center (BRC, Port Moresby, PNG) and the scientists attending to the mission. Hymenoptera families were sorted by Sharon Agovaua (National Agricultural Research Institute, Port Moresby, PNG), Bradley Gewa (Binatang Research Center, Madang, PNG) and Gilhem Duvot (MNHN, France) contributed to sorting Hymenoptera specimens at family level under the supervision of Claire Villemant who then coordinated their dispatching to specialists.
