裸露的丝状和网状原生动物长期被归类为蛋白酶或留在更高的群体之外。本研究共培养了8株丝状或网状裸藻，进行了光镜、18 S rDNA测序和系统发育学研究（均为尾藻），并对80个环境型进行了18 S rDNA测序。丝状种属于丝状亚门，网状种属于内黏亚门，使蛋白黏菌科成为多系。因此，我们将经典的主要是网状Proteomyxidea转移到Endomyxa，删除明显的filosans作为新的纲Granofilosea（包括Desmothoracida，Acinetactis和新的太阳单胞菌科Heliomorphidae（新属Heliomorpha（= Dimorpha）。文章题目水丝藻属五新种。（L. mylnikovi; L. anglica; L. longa）; L. oxoniensis; L. borokensis，以前被误认为是Biomyxa（Gymnophrys）cometa）形成一个大型淡水分支（新目Limnofilida）。Mesofila limnetica gen.，n.特殊的;和Nanofila marina gen.，n.特殊的;在Granofilosea（Cryptofilida ord. n.）在内黏菌属（Endomyxa）中，发现一新属网状蛋白黏菌（Filoreta marina，F. japonica，F.玉米属一个名词，F.（Corallomyxa）tenera comb.）形成一个分支（网囊藻纲），与Gromiidea/Ascetosporea有关。Platyreta germanica gen.，n.特殊的;和Arachnula impatiens是与Phytomyxea相邻的一个大分支内的相关吸血虫目（Arachulinida）。Biomyxidae和Rhizoprusplasmidae fam. n.在Proteomyxidea中保持不确定。Gymnophrydium和Borkovia进行了修订。网状珊瑚虫不像Filoreta，也可能不像Amoebozoa，而不是Cercozoa。(C)2008年Elsevier GmbH。All rights reserved.
Naked filose and reticulose protozoa were long lumped as proteomyxids or left outside higher groups. We cultivated eight naked filose or reticulose strains, did light microscopy, 18S rDNA sequencing and phylogeny (showing all are Cercozoa), and sequenced 80 environmental 18S-types. Filose species belong in subphylum Filosa and reticulose ones in subphylum Endomyxa, making proteomyxids polyphyletic. We therefore transfer the classically mainly reticulose Proteomyxidea to Endomyxa, removing evident filosans as new class Granofilosea (including Desmothoracida, Acinetactis and new heliomonad family Heliomorphidae (new genus Heliomorpha (= Dimorpha)). Five new species of Limnofila gen. n. (L. mylnikovi; L. anglica; L. longa; L. oxoniensis; L. borokensis, previously misidentified as Biomyxa (Gymnophrys) cometa) form a large freshwater clade (new order Limnofilida). Mesofila limnetica gen., sp. n. and Nanofila marina gen., sp. n. group separately in Granofilosea (Cryptofilida ord. n.). In Endomyxa, a new genus of reticulose proteomyxids (Filoreta marina, F. japonica, F. turcica spp. n., F. (Corallomyxa) tenera comb. n.) forms a clade (Reticulosida) related to Gromiidea/Ascetosporea. Platyreta germanica gen., sp. n. and Arachnula impatiens are related vampyrellids (Aconchulinida) within a large clade beside Phytomyxea. Biomyxidae and Rhizoplasmidae fam. n. remain incertae sedis within Proteomyxidea. Gymnophrydium and Borkovia are revised. The reticulose Corallomyxa are unlike Filoreta and possibly Amoebozoa, not Cercozoa. (C) 2008 Elsevier GmbH. All rights reserved.
