A distinctive new monotypic genus from Gabon is described in the tropical plant family Annonaceae: Sirdavidia, in honor to Sir David Attenborough. Molecular phylogenetic analyses confirm that Sirdavidia, which is very distinct from a morphological standpoint, is not nested in any existing genus of Annonaceae and belongs to tribe Piptostigmateae (su...
The Afrotropical Belostomatidae fauna has long proved to be a difficult taxonomic problem, not so much for the overwhelmingly large number of species involved but rather because of a lack of trained specialists. The rarity of some taxa also contributes to confusion, because some species remain poorly described or are known only from one or two spec...

Dans le cadre de nos travaux sur la biodiversité des pollinisateurs au sein du programme européen ALARM, nous présentons quelques conseils pour constituer une collection d'Apoïdes. La détermination des espèces d’abeilles passe par la nécessité de tuer, d’épingler et d’étaler les insectes. Ainsi, une préparation adaptée des spécimens facilite grande...
