Its phylogenetic position is a subject of some controversy. David Bass and colleagues considered it to be a vampyrellid within the Endomyxa clade of Rhizaria,[3] and the SSU rDNA sequence isolated from an organism described as Arachnula impatiens is indeed very close to that of the vampyrellid Theratromyxa.[4] The identification of this organism as Arachnula has, however, been questioned; and a separate amoeba identified as Arachnula by Yonas Isaak Tekle and colleagues groups in molecular phylogenies close to the amoebozoans Filamoeba and Flamella.[5] Which of these isolates corresponds to that originally described by Cienkowski is unresolved.
