The long-tailed planigale (''Planigale ingrami''), also known as Ingram's planigale or the northern planigale, is the smallest of all marsupials, and one of the smallest of all mammals. It is rarely seen but is a quite common inhabitant of the blacksoil plains, clay-soiled woodlands, and seasonally flooded grasslands of Australia's Top End. ==Taxonomy== The long-tailed planigale was described in 1906 by Oldfield Thomas, who placed it in the genus ''Phascogale''. The species was moved in 1928 by Ellis Le Geyt Troughton, who created the genus ''Planigale'' for it and the other then-known species, the common planigale (''P. maculata''), and described the narrow-nosed planigale (''P. tenuirostris''). The species has since suffered some taxonomic confusion, having been referred to as ''Planigale subtilissima''; there has also been some confusion concerning subspecies. Currently, three subspecies are recognised:〔 *''P. i. ingrami'', found in the Northern Territory to Townsville, Queensland; *''P. i. brunnea'', found in the Richmond area of Queensland; *''P. i. subtilissima'', found in the Ord Victoria Plain and the Kimberley region of Western Australia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Long-tailed planigale」の詳細全文を読む スポンサード リンク
