Fig. 6. A–J in A Huge Diversity of Metopids (Ciliophora, Armophorea) in Soil from the Murray River Floodplain, Australia. II. Morphology and Morphogenesis of Lepidometopus platycephalus nov. gen., nov. spec.

Fig. 6. A–J. Lepidometopus platycephalus, ciliary pattern and nuclear apparatus of early dividers (A–H) and of an early mid-divider (I, J) after protargol impregnation. Arrowheads mark the prospective adoral polykinetids formed at the posterior end of dorsal and dorsolateral kineties. Asterisks denote the prospective adoral polykinetids developing at the anterior end of the postoral kineties. Arrow in (I) points to two dorsolateral kineties which migrate towards the growing perizonal stripe to become perizonal rows 4' and 5' in the opisthe. BU – bulge; CV – contractile vacuole; MA – macronucleus; MI – dividing micronucleus; OAZP – opisthe's adoral zone of polykinetids; PAZP – proter's adoral zone of polykinetids; PM – paroral membrane; PPS – proter's perizonal stripe. Scale bars: 20 µm.
