Psilotrichides hawaiiensis in vivo (a, d–g) and after protargol impregnation (b, c). a ventral view of a representative individual. b, c Ventral (b) and dorsal (c) views of a representative specimen, showing ciliature and nuclear apparatus, arrows show the postoral cirri, hatched lines show cirri originating from the same cirral anlage. d–g Ventral views of representative individuals, arrowheads show the red eyespots of the green algae, arrow in (e) indicates the buccal ridge, arrows in (f) indicate the dorsal bristles, arrow in (g) shows the micronucleus. AZM, adoral zone of membranelles; CV, contractile vacuole; EM, endoral membrane; FV, food vacuole; LM, left marginal row; Ma, macronuclear nodules; Mi, micronucleus; PM, paroral membrane; RM, right marginal row; R1–4, ventral rows; TC, terminal cirrus; 1–3, dorsal kineties. Scale bars: 25 μm
