Megeremaeus cretaceous new species (Acari: Oribatida), the first oribatid mite from Canadian amber

  • Ekaterina A. Sidorchuk (a1) and Valerie M. Behan-Pelletier (a2)


Canadian Cretaceous amber belongs to the Taber Coal Zone, and was deposited in beds of coal and shale saturated with organic matter. It is upper Campanian (~76–72 million years ago), and the source of the original resin is predominantly the plant genus Parataxodium Arnold and Lowther (Cupressaceae). We describe the first oribatid mite from this amber, Megeremaeus cretaceous new species (Acari: Oribatida: Megeremaeidae). We provide a key to all described species of Megeremaeus Higgins and Woolley, 1965, and discuss the advantages that confocal microscopy provides for the study of dark, resin-filled, miniature amber inclusions.
