Saproxylic beetles – associated with dead wood or with other insects, fungi and microorganisms that decompose it – play a major role in forest nutrient cycling. They are important ecosystem service providers and are used as key bio-indicators of old-growth forests. In France alone, where the present study took place, there are about 2500 species distributed within 71 families. This high diversity represents a major challenge for specimen sorting and identification.The PASSIFOR project aims at developing a DNA metabarcoding approach to facilitate and enhance the monitoring of saproxylic beetles as indicators in ecological studies. As a first step toward that goal we assembled a library of DNA barcodes using the standard genetic marker for animals, i.e. a portion of the COI mitochondrial gene. In the present contribution, we release a library including 656 records representing 410 species in 40 different families. Species were identified by expert taxonomists, and each record is linked to a voucher specimen to enable future morphological examination. We also highlight and briefly discuss cases of low interspecific divergences, as well as cases of high intraspecific divergences that might represent cases of overlooked or cryptic diversity.

Originally from Asia, Hierodula patellifera (Serville, 1839) occurs several Mediterranean countries, such as Italy. These arrivals could come from many factors: new pets or commercial human transport. The presence of Hierodula patellifera (Serville, 1839) is here reported for the first time in France. A well settled and probably widespread population of this species is here discussed as its adaptability to the Mediterranean climate. Some considerations on the potential impacts on the local ecosystems and its future spreading in Europe as an invasive species are given.

This study aims at assessing mantid diversity and community structure in a part of the territory of the Sangha Tri-National UNESCO World Heritage Site in the Central African Republic (CAR), including the special forest reserve of Dzanga-Sangha, the Dzanga-Ndoki National Park. The study area is located in the biome of the dense tropical rainforest of the Congo Basin, the second largest area of tropical forest behind the Amazon basin, and one of the last regions on earth where pristine forest ecosystems persist. Between 1984 and 2012, eight collecting campaigns were conducted by P. Annoyer, M. Loubes and S. Danflous, with the aim of documenting invertebrate diversity in this remote and poorly studied area. Mantids were collected in different habitats and microhabitats using four harvesting techniques: visual hunting (threshing, mowing), active search in the trees, autonomous UV collecting (Remote Canopy Trap) and classical light trapping with mercury light. Community patterns were assessed using rarefaction curves and diversity estimators (ACE). Specimens (n = 25) were also found at the National Museum of Natural History (MNHN) of Paris. Seventy-one species of Mantodea are recorded from Sangha-Mbaere Region in the CAR from 1232 specimens. This is the first synthesis published about Mantodea in CAR. Some new species are present in the genera Cataspilota, Galepsus and Chlidonoptera. Taxonomic revisions of these genera are in progress. Some genera need global revision like Plistospilota, Miomantis, Entella, and Galepsus. This type of work is the first on the mantids in Central Africa since the various inventories carried out in the sixties and seventies, which were mainly based on lists of species. The contribution of data on ecology and biogeography is a novelty.
