Micrographs of two new species of subgenus Paraphysomonas from soil: Paraphysomonas solis crocotilla, P. dimorpha. (A – G)P. solis crocotilla. (H – M)P. dimorpha. (A) DIC of live P. solis crocotilla cells. (B – G)P. solis crocotilla TEMs. (B) Scales attached to cell, possible non-spine scales (arrows). (C) Possible extruded extrusomes (arrowheads). (D) Close-up of possible extrusomes and tapering tip of spine scales (double arrowhead) and aberrant scale form with bulbous tip. (E) Group of detached scales and visible mastigonemes (*). (F) Scales showing swollen spine bases; shadowy marks similar to scale base-plates possibly caused by scales washed off the grid during preparation (arrow). (G) Detached scale. (H) DIC of live P. dimorpha cells and one possible contaminant (cnt.) or dormant cell (see description), base-layer of scales visible (arrowhead). (I – M)P. dimorpha TEMs. (I) Whole cell with apparently just spine scales. (J) Whole cells with a mix of spined and plate scales. Mastigonemes (*). (K) Detached plate scales (arrow) from whole cell. (L) Detached spine scales. (M) Whole cell with only plate scales. Scale bar: A and H, 5 μm. (B) 2 μm. (C and D) 0.5 μm. E, F, G, I, J, K, L and M, 1 μm.
