蜷絲球蟲綱學名:Filasterea)是動物總界蜷絲動物下的一個類群,包括小球虫英语Ministeria快孢子虫英语Capsaspora兩類單細胞變形蟲[1]。蜷絲球蟲在演化樹上為領鞭毛動物(包括領鞭毛蟲動物界)的姐妹群,此分類單元於2008年基於分子種系發生學的證據提出[2][3][4]

分類 编辑

快孢子虫英语Capsaspora僅有單一物種Capsaspora owczarzaki,最早自淡水螺類紅扁蜷英语Biomphalaria glabrata體內採得[5][6],一度被認為是一種核形蟲[6],後經分子證據顯示其與動物較為接近[7][8],應屬動物總界[9]小球虫英语Ministeria則有Ministeria vibrans英语Ministeria vibransMinisteria marisola兩種,為自海水樣本中採得[10][11]。2017年又有另一屬生物Pigoraptor被發表描述,包括Pigoraptor vietnamicaPigoraptor chileana兩種,皆自淡水湖樣本中採得,分子證據顯示其屬於蜷絲球蟲,且與快孢子虫關係較近[4]
