Papua New Guinea possesses among the most remarkable ecosystems in the world in terms of plant species richness and marine biodiversity. During the biotic survey «Our Planet Reviewed - Papua New Guinea 2012-2013» more than two hundred people have explored these ecosystems, from the bottom of the Bismarck Sea to the summit of Mount Wilhelm, its highest peak. Assisted by both local communities and local parataxonomists, researchers, technicians, amateur naturalists and students from 21 different countries have gathered a large amount of specimens and data to attempt answering fundamental questions such as how many living species inhabit our planet or how much biodiversity is generated by elevational turnover of arthropod species. The Mémoires du Muséum publish the second volume about the major outcomes of the terrestrial part of the expedition, pushing forward the study of the arthropod fauna of Mount Wilhelm and presenting the plants collected during the expedition. This volume comprises 14 contributions dealing with diverse groups of insects, with the description of 118 species and 3 genera new to Science.
The Mémoires du Muséum publish the eighth volume of the series Zoologia Neocaledonica, dealing with the study of the fauna of New Caledonia, one of the «hot spots» of biodiversity in the Southern hemisphere. More than ever, the study of biodiversity in this megadiverse island is a current question. On the one hand, a growing number of molecular phylogenies bring crucial information about the origin and the evolution of local biodiversity. On the other hand, this biodiversity is more and more threatened by multiple landscape uses ant it deleterious consequences. In this context, systematic studies like those of Zoologia Neocaledonica are strongly needed as both a background and a primary source of knowledge, invaluable for evolutionary studies and land management policies.
This volume comprises 19 contributions on Lizards, Fishes and diverses Insects, with the description of many speces to Science, taking into account more than one hundred taxa from New Caledonia.
