Fig. 5. A–B in Integrative taxonomy of five astome ciliates (Ciliophora, Astomatia) isolated from earthworms in Central Europe

Fig. 5. A–B. Metaradiophrya lumbrici (Dujardin, 1841), Slovak specimens in vivo. Details of the anterior body portion, showing the fibrillar hook and its associated fibers. There are on average 6 (5–7) fibers attached to the upper right side of the longer arm, on average 33 (30–37) fibers to the ventral side of the longer arm and on average 11 (8–13) fibers to the left side of the shorter arm. Arrowheads mark the subapical suture extending from the right body margin over the fibrillar hook towards the left body margin. The somatic kineties above the suture run towards the anterior body end where they curve onto the dorsal body side to meridionally extend over its surface towards the posterior body end. On the other hand, the somatic kineties below the suture run meridionally over the ventral side towards the posterior body end. The ventral somatic kineties are lined with fibers attached to the fibrillar hook. Scale bars: 20 µm.
