This review is focused on morphological and anatomical characteristics of E. purpurea, E. angustifolia, E. pallida...
The morphology of the spermatheca and eggs of Odontotarsus purpureolineatus were studied by optical microscopy and scanning electron microscopy. The spherical eggs were about 1.35 mm long and 1.09 mm wide. The egg batches generally consist of 13–14 eggs. The egg surface is covered by polygonal (hexagonal and pentagonal shapes prevail) ridges and tiny chorionic tubercles. There were 8–10 aero-micropylar...
The morphology and morphometry of five soil haptorid ciliates (Apospathidium terricola, Diplites telmatobius, Armatoenchelys geleii, Paraenchelys terricola, and Spathidium aciculare), collected from a variety of terrestrial habitats in Slovakia (Central Europe), were investigated using live observation and protargol impregnation. Emphasis was given on the ciliary pattern, the fine structure of dorsal...
