This study addresses the diversity of deep soil beetles on the old continental island of Madagascar. We highlight Coleoptera as the only order of insects repeatedly occupying the deep soil (=endogean) habitat. We describe and illustrate soil flotation technique used during our fieldwork in Madagascar in December 2019. We focus on the method's high-output and mobile technicalities. We document 51 deep soil samples, each about 20 litres in volume, taken by us in varying Malagasy localities (Andringitra, Road RN7, Ankaratra, Andasibe) and habitats (primary forest versus grassland). We provide a preliminary illustrated overview of 1,430 deep soil beetles of Madagascar sampled by us. They include representatives of Carabidae (Anillini, Reicheiina), Leiodidae, Staphylinidae (Aleocharinae, Euaesthetinae, Osoriinae, Paederinae, Pselaphinae, Scydmaeninae), Scarabaeidae, Tenebrionidae and Curculionidae. We emphasize the significant disparity between collecting 1,430 adult endogean beetles and only about a dozen of their larvae, all belonging to Scydmaeninae.
这项研究探讨了马达加斯加这个古老大陆岛屿上的深土甲虫多样性。我们强调鞘翅目是唯一一类反复占据深土（=内栖）生境的昆虫目。我们描述并说明了在 2019 年 12 月于马达加斯加进行野外工作时使用的土壤浮选技术。我们专注于该方法的高效和移动特性。我们记录了 51 个深土样本，每个样本约 20 升，是在不同的马达加斯加地区（安德里安齐特拉、RN7 公路、安纳拉特拉、安达西贝）和生境（原始森林与草原）采集的。我们初步概述了由我们采集的 1430 种深土甲虫。它们包括 Carabidae（Anillini、Reicheiina）、Leiodidae、Staphylinidae（Aleocharinae、Euaesthetinae、Osoriinae、Paederinae、Pselaphinae、Scydmaeninae）、Scarabaeidae、Tenebrionidae 和 Curculionidae 的代表。我们强调了采集 1430 只成年内栖甲虫和仅十几个幼虫之间的显著差异，所有幼虫都属于 Scydmaeninae。
