Fig. 3 in Morphological Redescription and SSU rDNA-based Phylogeny of Two Freshwater Ciliates, Uronema nigricans and Lembadion lucens (Ciliophora, Oligohymenophorea), with Discussion on the Taxonomic Status of Uronemita sinensis

Fig. 3. Photomicrographs of Uronema nigricans from life (A–E, in bright field illumination) and after protargol (F–M) staining. (A–C) Right ventrolateral views of representative individuals, with cell in C slightly depressed. Arrow in A shows contractile vacuole, while in C indicates macronucleus. (D) View of caudal portion of another cell, arrow points to caudal cilium. (E) Different body sizes, showing conspicuous apical plate. (F, G) Ventral views of stained individuals, indicating the structure of scutica. (H, I) Portion views of oral apparatus, revealing the number of kinety rows in M2 (two rows in H and three rows in I). (J, K) Ventral (J) and dorsal (K) view of a representative individual to show the ciliature and nuclear apparatus. Arrow in J points to basal body of caudal cilium, arrow in K indicating the apical plate. (L, M) Left ventrolateral (L) and right dorsolateral (M) view of another stained individual to show the ciliature and oral apparatus. Scale bars: 15 μm (A, B); 30 μm (E).Published as part of Liu, Mingjian, Li, Lifang, Qu, Zhishuai, Luo, Xiaotian, Al-Farraj, Saleh A., Lin, Xiaofeng & Hu, Xiaozhong, 2017, Morphological Redescription and SSU rDNA-based Phylogeny of Two Freshwater Ciliates, Uronema nigricans and Lembadion lucens (Ciliophora, Oligohymenophorea), with Discussion on the Taxonomic Status of Uronemita sinensis, pp. 17-37 in Acta Protozoologica 56 (1) on page 23, DOI: 10.4467/16890027AP.17.003.6967, http://zenodo.org/record/836437
