FIGURES 1–13 in Redescription of the marine scuticociliate Glauconema trihymene Thompson, 1966 (Protozoa: Ciliophora): life cycle and stomatogenesis

FIGURES 1–13. Glauconema trihymene (Qingdao population) from live cells (1–3, 8), after protargol (4a, 5a, 6–7, 12–13), silver nitrate (9–11) impregnations, and the oral apparatus of Urocryptum tortum (4b, 5b). (12) Trophont, side view, arrow indicates the apical plate. (3) Tomite, ventral view. (4a, 5a) Buccal apparatus of tomite and trophont, respectively. (4b, 5b) Buccal apparatus of tomite and trophont of Urocryptum tortum, respectively (after Pérez­Uz & Guinea 2001). (6, 7) Infraciliature of ventral (6) and dorsal (7) sides in trophont, arrowhead indicates the closely spaced M1 and M2. (8) Transformation between trophont and cyst stages. (9) Trophont, ventral view, arrow marks the inconspicuous gap (arrow) between M1 and M2 (after Thompson 1966). (10) Portion of buccal area showing silverline system, arrowhead indicating the closely arranged M1 and M2. (11) Caudal view of silverline system. (12–13) Tomite, infraciliature of ventral (12) and dorsal (13) sides, arrow indicates the large distance between M1 and M2. CCo = caudal cilium complex; Cs = cytostome; CVP = contractile vacuole pore; CyP = cytopyge; M1–3 = membranelle 1–3; PM = paroral membrane; Sc = scutica. Scale bars = 20 m.
