Challenging the Wallacean shortfall: A total assessment of insect diversity on Guadeloupe (French West Indies), a checklist and bibliography

This work is the first attempt to integrate into one list and quantify all the known species of Guade­loupean insects. It includes all the species known to us to be reported for the island of Guadeloupe until the 31st of December 2019. A total of 3097 valid species are listed, of which the largest component is the beetles (1447 species). Preliminarily, 632 species (20%) are considered to be strictly endemic to Guadeloupe, and 250 species are recognized as adventive or introduced. The bibliography complements the taxonomic information and includes over 350 titles. Brief annotations are also given on the history of entomology in Guadeloupe. This list includes four new island records for Guadeloupe: Azeta rhodogaster Guenée, 1852 (Lepidoptera: Erebidae), Eudocima apta (Walker, 1857) (Lepidoptera: Erebidae), Urania leilus (Linnaeus, 1758) (Lepidoptera: Uraniidae) and Micronotus quadriundulatus (Redtenbacher, 1892) (Orthoptera: Tetrigidae), all recently collected in Guadeloupe.

A new Evaniid wasp for Reunion Island (Hymenoptera, Evaniidae)

Résumé : Une nouvelle guêpe Evaniidae pour La Réunion (Hymenoptera). La faune des Evaniidae de La Réunion ne comprenait qu'une seule espèce jusqu'à présent, Evania appendigaster (Linnaeus, 1758). Une seconde espèce est ici rapportée pour la première fois de l'île, Prosevania erythrosoma (Schletterer, 1886). La biologie de chacune des guêpes est précisée. Une clé d'identification des Evaniidae de La Réunion est proposée.Abstract: 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.Mots clés : Evania appendigaster, Prosevania erythrosoma, parasitoïde, espèce introduiteKeywords: Evania appendigaster, Prosevania erythrosoma, parasitoid, introduced specie

Pseudoscorpions (Arachnida, Pseudoscorpiones) from French Polynesia with first species records and description of new species

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 assimilis (Beier, 1932). New localities of Geogarypus longidigitatus (Rainbow, 1897) are added. An identification key to pseudoscorpions of French Polynesia is provided

Categorization of species as native or nonnative using DNA sequence signatures without a complete reference library.

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 of taxonomic expertise. Among these methods, DNA sequence barcoding (also known as "DNA barcoding") and by extension, meta-barcoding for biological communities, has emerged as one of the most frequently utilized methods for DNA-based species identifications. Unfortunately, the use of DNA barcoding is limited by the availability of complete reference libraries (i.e., a collection of DNA sequences from morphologically identified species), and by the fact that the vast majority of species do not have sequences present in reference databases. Such conditions are critical especially in tropical locations that are simultaneously biodiversity rich and suffer from a lack of exploration and DNA characterization by trained taxonomic specialists. To facilitate efforts to document biodiversity in regions lacking complete reference libraries, we developed a novel statistical approach that categorizes unidentified species as being either likely native or likely nonnative based solely on measures of nucleotide diversity. We demonstrate the utility of this approach by categorizing a large sample of specimens of terrestrial insects and spiders (collected as part of the Moorea BioCode project) using a generalized linear mixed model (GLMM). Using a training data set of known endemic (n = 45) and known introduced species (n = 102), we then estimated the likely native/nonnative status for 4,663 specimens representing an estimated 1,288 species (412 identified species), including both those specimens that were either unidentified or whose endemic/introduced status was uncertain. Using this approach, we were able to increase the number of categorized specimens by a factor of 4.4 (from 794 to 3,497), and the number of categorized species by a factor of 4.8 from (147 to 707) at a rate much greater than chance (77.6% accuracy). The study identifies phylogenetic signatures of both native and nonnative species and suggests several practical applications for this approach including monitoring biodiversity and facilitating biosecurity

A DNA barcode-based survey of terrestrial arthropods in the Society Islands of French Polynesia : host diversity within the SymbioCode Project

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., Wolbachia) and other genetic material among branches of the arthropod tree. The sample includes an estimated 1127 species, of which 1098 included at least one DNA-barcoded specimen and 29 were identified to species level using morphological traits only. Species counts based on molecular data emphasize that some groups have been understudied in this region and deserve more focused taxonomic effort, notably Diptera, Lepidoptera and Hymenoptera. Some taxa that were also subjected to morphological scrutiny reveal a consistent match between DNA and morphology-based species boundaries in 90% of the cases, with a larger than expected genetic diversity in the remaining 10%. Many species from this sample are new to this region or are undescribed. Some are under description, but many await inspection by motivated experts, who can use the online images or request access to ethanol-stored specimens.Peer reviewe

A new Cetoniinae for the French Polynesia fauna (Coleoptera, Scarabaeidae)

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.Une nouvelle Cétoine pour la faune de Polynésie française (Coleoptera, Scarabaeidae). La faune des Cetoniinae de Polynésie française, qui ne comprenait jusqu’à présent qu’une espèce introduite, Protaetia fusca (Herbst, 1790), compte désormais une seconde espèce, connue en Polynésie pour l’instant de Tahiti seulement, Glycyphana stolata (Fabricius, 1781).
