Abstract：
:The species Leptomyxa flabellata was described by Goodey in 1915 and re-isolated by Pussard and Pons in 1976. It seems that it was never seen (or never recognized) again since that time. The strain designated as "Leptomyxa flabellata CCAP 1546/2" was studied by Cann in 1984, however the quality of the electron microscopic images of that time was poor. Based on the cyst structure and size characters, Page in 1988 suggested that this strain is not co-specific with Goodey's Leptomyxa flabellata, but represents a species 'Ripidomyxa' australiensis Chakraborty and Pussard, 1985, nowadays known as Rhizamoeba australiensis. In the present paper light- and electron-microscopic images of CCAP 1546/2 strain, which is now lost, are provided. Based on the morphological evidences it is suggested to establish it in a rank of a new species, Leptomyxa ambigua n. sp. Neither "true" L. flabellata Goodey, 1915 nor original R. australiensis Chakraborty et Pussard, 1985 are nowadays represented in the culture collections, and no original type material is available on both these species.
