FIGURE 1. Frontonia didieri n. sp. from living cells (A), after protargol (B, C, E, G) and silver carbonate impregnations (D, F). (A) Ventral view of a typical specimen. (B) Ventral view of an individual in division. (C, D, F) To show the general infraciliature. (G) To show the oral apparatus, note the long vestibular kineties (VK) and two-rowed paroral membrane (PM).
