<strong>Endogean beetles (Coleoptera) of Madagascar: deep soil sampling and illustrated overview</strong>

This study addresses the diversity of deep soil beetles on old continental island Madagascar. We highlight Coleoptera as only order insects repeatedly occupying (=endogean) habitat. describe and illustrate flotation technique used during our fieldwork in Madagascar December 2019. focus method’s high-output mobile technicalities. document 51 samples, each about 20 litres volume, taken by us varying Malagasy localities (Andringitra, Road RN7, Ankaratra, Andasibe) habitats (primary forest versus grassland). provide a preliminary illustrated overview 1,430 sampled us. They include representatives Carabidae (Anillini, Reicheiina), Leiodidae, Staphylinidae (Aleocharinae, Euaesthetinae, Osoriinae, Paederinae, Pselaphinae, Scydmaeninae), Scarabaeidae, Tenebrionidae Curculionidae. emphasize significant disparity between collecting adult endogean dozen their larvae, all belonging to Scydmaeninae.
