Islands are areas where biodiversity conservation is of the utmost importance and is particularly challenging due to the isolation and vulnerability of animal and plant populations. The coastline of Brittany includes a large number of islands, which vary greatly in size, distance from the mainland, landscape composition and climate. Until recently,...

Two new whip spider species of the genus Charinus Simon, 1892, are described based on seven specimens collected in Guadeloupe (Grande-Terre) and three specimens collected in northern Martinique. The new taxa described here, Charinus grandisterrae n. sp. and C. marechali n. sp., raise the number of currently recognized species for the genus Charinus...

An All Taxa Biodiversity Inventory (ATBI) is a comprehensive inventory of all species occurring in a given territory. Conceptualized in the 1990s by North American biologist Daniel Janzen, ATBI aims to accelerate the pace of inventorying arthropods. Over the past 15 years, in France and Belgium, around 19 sites have implemented or are implementing...

L'entomofaune des forêts mésophiles de Lépinay (Rivière-Pilote et Sainte-Luce) et de Montravail (Sainte-Luce), a été inventoriée du 9 au 28 avril 2023. Le dispositif d’échantillonnage est proche de celui mis en place lors des différentes campagnes d’inventaire de l’entomofaune des ZNIEFF conduites entre 2011 et 2021. Le protocole intègre un nombre...

Large parts of the Pacific were thought to host low bee diversity. In Fiji alone, our recent estimates of native bee diversity have rapidly increased by a factor of five (from 4 to >22). Here, we show how including sampling of the forest canopy has quickly uncovered a new radiation of Hylaeus (Hymenoptera: Colletidae) bees in Fiji. We also show tha...

A new species Olpium caputi sp. nov. from Tahiti is described here based on external characters. This is the first record of the family Olpiidae Banks, 1895 from French Polynesia. Additionally, the genus Paratemnoides Harvey, 1991 is recorded from French Polynesia for the first time with the full description of new-found specimens of Paratemnoides...

The sampling scheme is similar to the one set up for the entomologica...

The entomofauna of four natural areas of ecological, faunistic and floristic interest (ZNIEFF) located in the rainforests of north-central Martinique ( Lesser Antilles) was sampled in 2021. In addition, a control station in a rural area and secondary woodland, Fond Marie-Reine (Champflore), was added, whose purpose is to calibrate the heritage valu...

Neuroptera from French Polynesia, with the description of a new species of Micromus Rambur, 1842. Within a sample of forty imagos collected in French Polynesia, seven species were identified: Distoleon bistrigatus (Rambur, 1842) (Myrmeleontidae); Austromegalomus brunneus Esben-Petersen, 1935, and Micromus societatis n. sp., a suspected endemic spec...

The richness of the terrestrial fauna of French Polynesia is discussed, with emphasis on the beetle family Staphylinidae. Currently, members of the subfamily Scaphidiinae are unrecorded from the archipelago or even the whole French Polynesia. The first member of this subfamily, Scaphisoma jacqi n. sp., was collected on the Raiatea Island and is des...

New genetic diagnostic approaches have greatly aided efforts to document global biodiversity and improve biosecurity. This is especially true for organismal groups in which species diversity has been underestimated historically due to difficulties associated with sampling, the lack of clear morphological characteristics, and/or limited availability...

La grande nébrie, carabe qui se trouve exclusive-ment sur l'estran sableux, était présente presque tout le long de la côte atlantique continentale fran-çaise il y a encore 30 à 40 ans. Aujourd'hui, cette espèce ne semble plus fréquenter que quelques îles bretonnes et une île vendéenne.

Introduction -Mango (Mangifera indica L.) is the second most important tropical fruit produced worldwide. In Reunion Island, serious losses are the result of damage caused by Orthops palus (Taylor, 1947) (Heteroptera, Miridae). This bug sucks the sap of mango inflorescences, causing them to dry out. However, little is known about this pest and the...

Putting a name on species, using names from a checklist and knowing the geographical range are basic knowledge prior to any conservation action directed to species biodiversity. Using examples, we show that for invertebrates: descriptions and country records are still growing in metropolitan France and often relates to endemic species; that nonprof...

Calliphara bifasciata White, 1839, known from Fiji, Wallis and Futuna and the Samoa, is reported for the first time from the Society Islands in French Polynesia. Its diagnosis, as well as the sparse known ecological data, are discussed.

We report here on the taxonomic and molecular diversity of 10 929 terrestrial arthropod specimens, collected on four islands of the Society Archipelago, French Polynesia. The survey was part of the ‘SymbioCode Project’ that aims to establish the Society Islands as a natural laboratory in which to investigate the flux of bacterial symbionts (e.g., W...

The Evaniid fauna of Reunion was until now restricted to a single introduced species, Evania appendigaster (Linnaeus, 1758). A second species is here reported from the island Prosevania erythrosoma (Schletterer, 1886). The biology of both species is discussed. An identification key for the Evaniid species of Reunion island is proposed.

Dans la poursuite des inventaires menés depuis 2011, l'entomofaune de quatre zones naturelles d'intérêt écologique, faunistique et floristique (ZNIEFF) situées dans le sud et le sud-ouest de la Martinique a été échantillonnée au titre du programme d’étude 2015. Des techniques de collecte variées (pièges d'interception, piège lumineux, pièges aérien...

Island plant–pollinator networks are typically simpler than their continental counterparts and this can make them less resilient to disturbance from exotic species. French Polynesia has a very low diversity of bees, but their status as either native or introduced species has been largely speculative. We combine previous studies with new DNA sequenc...

Cette note traite de l’étude d’un lot d’araignées récoltées en Polynésie française entre 2009 et 2014. 52 espèces ont été identifiées, en provenance des îles de la Société, de l’archipel des Tuamotu, des Gambier, des îles Australes et des Marquises. Deux espèces nouvelles – Theridion charlati n. sp. et Glenognatha ledouxi n. sp. – sont décrites de...

The Cetoniinae fauna of French Polynesia was restricted until now to a single introduced species, Protaetia fusca (Herbst, 1790). A second species is here reported from Tahiti, Glycyphana stolata (Fabricius, 1781). P. fusca is also reported from the Marquesas Islands for the first time. Résumé. – Une nouvelle Cétoine pour la faune de Polynésie fran...

The sphecid fauna of French Polynesia, limited until now to Sceliphron caementarium (Drury), is increased by three species recently introduced in the Society Islands: Sceliphron laetum (Smith), S. curvatum (Smith) and Chalybion bengalense (Dahlbom). The presence of S. curvatum in French Polynesia considerably broadens the known distribution of this...

Chrysis angolensis Radoszkowski, 1881, has been collected in the Marquesas and Society Islands and this is the first report for this species and for the family Chrysididae in French Polynesia.
