Large tropical trees are rightly perceived as supporting a plethora of organisms. However, baseline data about the variety of taxa coexisting on single large tropical trees are lacking and prevent a full understanding of both the magnitude of biodiversity and the complexity of interactions among organisms in tropical rainforests. The two main aims...

In this study, we reassess the phylogenetic relationships of the genus Sesamia Guenée, 1852 and examine in more detail the members of the nonagrioides species group, for which three distinct species complexes are identified. The calamistis subgroup comprises eight species, of which four new species are described: Sesamia kabirara Le Ru sp. nov., Se...

New footage confirms Hemiceratoides moths to be bird tear-drinking. Bionomics of Hemiceratoides is updated, and its taxonomy revised, with descriptions of Hemiceratoides ornithopotis sp. nov. and H. avimolestum sp. nov., while Cynisca thysbe, type species of Siccyna (= Cynisca), is re-combined as H. thysbe comb. nov. (thus Hemiceratoides = Siccyna...

The opening of habitats associated with the emergence of C4 grasslands during the Neogene has had a massive influence on the evolution of plant and animal communities. Strikingly, the impacts of grassland expansion on species diversification in Africa, where the largest surface of grasslands and savannas in the world is located, are not well unders...

Habitus and genitalia of the three species are figured and compared with those of the closest taxa.

Une pression de prospection plus élevée ces dernières années en Corse a permis de recenser plusieurs espèces de Lépidoptères nouvelles pour l'île. Dans la continuité de celles déjà rapportées dans de précédentes publications, le présent article fait état de huit nouveaux Macrohétérocères pour la Corse et relate l'observation de sept espèces remarqu...

In this study, 31 species of noctuid stemborers belonging to the genus Sesamia Guenée, 1852 (Lepidoptera: Noctuidae: Noctuinae: Apameini: Sesamiina) are reviewed. All these species are assigned to the Sesamia cretica group sensu Tams & Bowden (1953). Based on genitalic characters, several subgroups are hereby defined. Nine species belong to a speci...

The revision of the genus Rhododactyla Warren, 1889, is proposed. Rh. micra Hampson, 1926, is excluded from this genus and transfered in a new genus, Densupalpa n. gen. Sinosia inornata Schaus, 1914, is integrated in the genus Rhododactyla and the genus Sinosia is synonymized. Three new species are described: Rh. rosea n. sp., described from three...

ALEXANOR, 29 (8) : 617-641. -- Alors que Noctua interposita paraissait il y a encore peu de temps se cantonner, en France, à la chaîne pyrénéenne, l'espèce semble avoir entrepris assez récemment une étonnante progression dans le Massif Central et les Alpes, où le Papillon se montre même assez commun dans certaines localités. ///////////////////// N...

DNA barcoding analyses of Phragmatiphila nexa (Hübner, 1808) populations unveiled an unexpected divergence in mtDNA of Italian populations, showing the existence of three allopatric cryptic species. The northernmost BIN is shared with specimens from most other European countries, the southernmost one includes specimens from Basilicata and Calabria...

"The Planet Reviewed in Corsica" is an expedition by the MNHN in partnership with the Collectivité de Corse and the French Office for Biodiversity.

Une pression de prospection plus élevée ces dernières années en Corse a permis de recenser plusieurs espèces de Lépidoptères nouvelles pour l'île. Au-delà de celles déjà rapportées dans d'autres publications, le présent article fait état de huit nouveaux Macrohétérocères, parmi lesquels Condica viscosa est également nouveau pour la France, et Polyp...

While scales ensure hydrophobicity in opaque Lepidoptera, their reduction in clearwing species question hydrophobicity and its dependency on wing microstructures (scale presence, morphology, insertion, coloration) and nanostructures (scale ridge features). By measuring static contact angle (CA) of water droplets at different stages of evaporation i...

In water, transparency seems an ideal concealment strategy, as testified by the variety of transparent aquatic organisms. By contrast, transparency is nearly absent on land, with the exception of insect wings, and knowledge is scarce about its functions and evolution, with fragmentary studies and no comparative perspective. Lepidoptera (butterflies...

The noctuid genus Spodoptera currently consists of 31 species with varied host plant breadths, ranging from monophagous and oligophagous non-pest species to polyphagous pests of economic importance. Several of these pest species have become major invaders, colonizing multiple continents outside their native range. Such is the case of the infamous f...

Transparency is common in aquatic environments where it reduces detectability by predators. Transparency degree (the proportion of transmitted light) varies under water and is higher as light availability increases. Transparency is rare on land and poorly studied. Recent studies have shown that Lepidoptera, a group in which transparency has indepen...

In this study nine new Acrapex species are described: Acrapex abyssinica n. sp., Acrapex dabaga n. sp., Acrapex jansei n. sp., Acrapex kifanya n. sp., Acrapex lusinga n. s...

Transparency in Lepidoptera: structural bases of the costs for water repellency Transparency is abundant and well-studied in aquatic organisms, but rare and poorly known for terrestrial organisms. It is present on insect wings where it likely reduces detectability by visually-hunting predators 1. Lepidoptera are characterized by wings covered with...

The rise of Neogene C 4 grasslands is one of the most drastic changes recently experienced by the biosphere. A central-and widely debated-hypothesis posits that Neogene grasslands acted as a major adaptive zone for herbivore lineages. We test this hypothesis with a novel model system, the Sesamiina stemborer moths and their associated host-grasses....

The genus Spodoptera Guenée (Lepidoptera, Noctuidae, Noctuinae) is a group of economical importance which encompasses several major pests of crops worldwide. Although this genus has been the focus of many studies, the status of several Spodoptera species is still unstable, especially in the light of recent molecular analyses. In 2015 five Spodopter...

This study focuses on the importance in hyperdiverse regions, such as the Amazonian forest, of accelerating and optimising the census of invertebrate communities. We carried out low‐intensity sampling of tropical moth (Lepidoptera) assemblages in disturbed forest fragments in Brazil. We combined DNA barcoding and taxonomists’ expertise to produce f...

Nowadays molecular species delimitation methods promote the identification of species boundaries within complex taxonomic groups by adopting innovative species concepts and theories (e.g. branching patterns, coalescence). As some of them can efficiently deal with large single-locus datasets, they could speed up the process of species discovery comp...

Nous contribuons à la connaissance du genre Eulepidotis Hübner, 1813, avec la description de deux nou-velles espèces provenant de la Réserve Naturelle des Nouragues en Guyane française : Eulepidotis poirieri n. sp. qui est décrit sur un unique specimen femelle et Eulepidotis albipuncta n. sp. qui est décrit sur cinq specimens femelles.

Phragmatiphila nexa (Hübner, 1808) was studied in 2007 within the framework of an action plan. This article presents information dealing with taxonomy, biology, ecology and a conservation value assessment. According to literature, this eurasiatic noctuid moth is mainly to be found in the continental biogeographical region of Europe. It inhabits mar...

Between the late Oligocene and the early Miocene, climatic changes have shattered the faunal and floral communities and drove the apparition of new ecological niches. Grassland biomes began to supplant forestlands, thus favouring a large-scale ecosystem turnover. The independent adaptive radiations of several mammal lineages through the evolution o...

Relationship between stem clade age and extant diversity for Apameini moths. Results indicate that there is no evident relationship between the age of a group and its diversity. Apamea and Abromias are recent lineages and species-rich, and many remaining lineages have a deficit of species. It appears that variations in diversification rates among l...

La sous-famille des Plusiinae a toujours suscité l'admiration des entomologistes. La plupart des espèces ont des livrées satinées avec des couleurs qui peuvent être vert métallisé, dorées ou cuivrées, des motifs délicats, souvent ornés d'une sub-orbiculaire argentée. Ces Noctuelles aux moeurs souvent particulières (migrations, activité diurne, etc....
