To date, the only characterised member of this genus is Satchyamoeba lipophora
an amoeba of length 22mm
isolated from agricultural soil in Fife, Scotland. This amoeba
alternates between a Vahlkampfiid-like eruptive mode to a flattened,
expanded morphology (much as I have found with Heteramoeba
clara). The species name arises from the possession of a
single very prominent and large lipid body. S. lipophora produces
a cyst of diameter 10mm.
The outer layer has crenulations giving these cysts a similar appearance
to some members of the genus Acanthamoeba.
A Stachyamoeba sp. strain is available from the ATCC (see below)
that was isolated in 1990 from the Atlantic ocean by T.K Sawyer, the 16S
ribosomal RNA gene has been sequenced.
