Abstract

Abstract. The Australian cryptorhynchine weevil genus Tentegia Pascoe, 1873 is unique among Curculionoidea due to its coprophagous life style. The adults roll or pull marsupial dung pellets and cache them under logs, and the larvae develop in the pellets. In a remarkable case of convergent evolution, Tentegia is the only known beetle taxon outside of Scarabaeinae (Scarabaeidae) with such dung-rolling and nesting habits. In this paper the taxonomy of Tentegia is revised, including the redescription of the genus, descriptions of the six former species and three new species from the Northern Territory, T. tompsetti sp. nov., T. grossbechleri sp. nov. and T. weiri sp. nov. Lectotypes are designated for Tentegia quadriseriata Lea, 1912, Tentegia amplipennis Lea, 1930, T. quadrisignata Lea, 1910, T. anopla Lea, 1908, T. bisignata Pascoe and T. quinquesinuata Lea. All species are illustrated and their distributions are mapped, revealing the genus to occur in monsoonal and arid ecosystems of the Northern Territory, Queensland, New South Wales, South Australia and Western Australia. The dung-rolling behaviour of Tentegia stupida (Fabricius) is documented on video recordings for the first time.

粪甲虫的冒名顶替者:澳大利亚象鼻虫Tentegia Pascoe属的修订和Tentegia stupida (Fabricius)的粪滚动行为(curculionae: Molytinae: Cryptorhynchini)

摘要澳大利亚隐象鼻虫属Tentegia Pascoe, 1873年，由于其食腐的生活方式，在象鼻虫科中是独特的。成虫滚或拉有袋类动物的粪球，藏在圆木下，幼虫在粪球中发育。在趋同进化的一个显著案例中，Tentegia是金龟子科(金龟子科)之外唯一已知的具有这种滚粪和筑巢习惯的甲虫分类群。本文对天蚕属的分类学进行了修订，包括该属的重新描述、6个原种和3个北领地新种的描述、T. tompsetti sp. nov.、T. grossbechleri sp. nov.和T. weiri sp. nov.的分类，并对1912年、1930年、1910年、1908年、1908年、bisignata Pascoe和ququesinuata Lea的分类进行了确定。所有的物种都被绘制出来，它们的分布被绘制出来，揭示了该属出现在北领地、昆士兰、新南威尔士、南澳大利亚和西澳大利亚的季风和干旱生态系统中。在视频记录中首次记录了笨蛛(Tentegia stupida)的滚粪行为。
