    Abstract The genus Copelatus Erichson, 1832 (Coleoptera, Dytiscidae, Copelatinae) of Madagascar is revised in two parts. This review is restricted to the Copelatus species that have fewer than ten elytral + one submarginal stria, including all species except those of the erichsonii species group. Both morphological and molecular (mitochondrial COI) data are used in an integrative taxonomic approach. Thirteen species are recognised, of which five are described as new: Copelatus ankaratra sp. nov., Copelatus kely sp. nov., Copelatus pseudostriatus sp. nov., Copelatus safiotra sp. nov. and Copelatus vokoka sp. nov.Copelatus unguicularis Régimbart, 1903 and Copelatus apicalis Fairmaire, 1898 are both transferred to the genus Madaglymbus Shaverdo & Balke, 2008 (comb. nov.). Copelatus mimetes Guignot 1957 is a junior synonym of the widespread Afrotropical–Arabian Copelatus pulchellus (Klug, 1834) (syn. nov.). Copelatus marginipennis (Laporte, 1835) is reinstated (stat. nov.) as a valid species with Copelatus aldabricus Balfour-Browne, 1950 and Copelatusaldabricusvar.simplex Guignot, 1952 as junior synonyms (syn. nov.). We designate lectotypes for Colymbetes marginipennis Laporte, 1835 and Copelatus obtusus Boheman, 1848. Copelatus peridinus Guignot, 1955 is recorded for Madagascar for the first time and Copelatus nodieri Régimbart, 1895 is rejected as a species present in Madagascar.

    Abstract Varroa destructor is an invasive alien species that has been reported parasitizing the endemic honey bee of Madagascar, Apis mellifera unicolor, since 2010. Studying its nuclear genetic diversity and structure was our main goal. Using 11 microsatellite loci and 344 mites collected from 12 apiaries, we observed a low genetic diversity, with only 8 multilocus genotypes (MLG) identified. V. destructor populations form a single genetic cluster, clonal richness ranged from 0.02 to 0.20, and number of MLG within apiaries varied between one and six MLGs. About 69.5% of the mites analyzed harbored the same genotype (100%, homozygous), and 23.3% had a genotype differing by a single allele. The overall low diversity observed suggests one or multiple introductions of similar genotypes. The greater abundance of MLGs in High Land apiaries (eight MLGs) than on the east coast (two MLGs) and the presence of particular MLGs in High Land apiaries favor the hypothesis that V. destructor has been first introduced close to the international airport, and then spread to other regions by commercial exchanges.

    Abstract Resolving ecological-economic trade-offs between biodiversity and yields is a key challenge when addressing the biodiversity crisis in tropical agricultural landscapes. Here, we focused on the relation between seven different taxa (trees, herbaceous plants, birds, amphibians, reptiles, butterflies, and ants) and yields in vanilla agroforests in Madagascar. Agroforests established in forests supported overall 23% fewer species and 47% fewer endemic species than old-growth forests, and 14% fewer endemic species than forest fragments. In contrast, agroforests established on fallows had overall 12% more species and 38% more endemic species than fallows. While yields increased with vanilla vine density and length, non-yield related variables largely determined biodiversity. Nonetheless, trade-offs existed between yields and butterflies as well as  reptiles. Vanilla yields were generally unrelated to richness of trees, herbaceous plants, birds, amphibians, reptiles, and ants, opening up possibilities for conservation outside of protected areas and restoring degraded land to benefit farmers and biodiversity alike.
