Fig. 6 in Studies on Three Diverse Frontonia Species (Ciliophora, Peniculida), with Brief Notes on 14 Marine or Brackish Congeners

Fig. 6. Photomicrographs of the Chinese populations of fourteen Frontonia species in vivo (A, C, E, G, I, K, M, O, Q, S, U, W, Y, Z1), after protargol impregnation (B, F, H, L, N, P, T, X, Z, Z2) and Chatton-Lwoff silver nitrate impregnation (D, J, R, V). A, B – Frontonia magna Fan et al., 2011 (from Fan et al. 2011a); C, D – F. mengi Fan et al., 2011 (from Fan et al. 2011a); E, F – F. guangdongensis spec. nov. (from present work); G, H – F. ocularis Bullington, 1939 (from present work); I, J – F. multinucleata Long et al., 2008 (from Long et al. 2008); K, L – F. schaefferi Bullington, 1939 (from present work); M, N – F. pusilla Fan et al., 2013 (from Fan et al. 2013); O, P – F. elegans Fan et al., 2013 (from Fan et al. 2013); Q, R – F. lynni Long et al., 2005 (from Long et al. 2005); S, T – F. canadensis Roque and Puytorac, 1972 (from Pan et al. 2013); U, V – F. tchibisovae Burkovsky, 1970 (from Long et al. 2008); W, X – F. subtropica Pan et al., 2013 (from Pan et al. 2013); Y, Z – F. didieri Long et al., 2008 (from Long et al. 2008); Z1, Z2 – F. sinica Fan et al., 2013 (from Fan et al. 2013). Larger arrows mark contractile vacuoles, larger arrowheads show peniculus 3. P1–P3 – peniculi 1, 2, 3, PM – paroral membrane, PK – postoral kineties, VK – vestibular kineties. Scale bars: A = 150 μm, C, Q, S, U = 80 μm, E, G, Y, Z1 = 60 μm, I, K, O = 40 μm, M = 50 μm, W = 100 μm.
