Fig. 2. Morphology and ciliature of Thuricola obconica. (A) Narrow side view of an individual with two zooids. (B) Narrow side view of an individual with single zooid. (C) Narrow side view of an individual with single zooid, to show macronucleus. (D) Wide side view of an individual with two zooids. (E) Wide side view of lorica. (F–H) Narrow side view of different curved lorica. (I) Base of lorica. (J) Detail of pellicle, to show the transverse striations and trochal band. (K) Model pattern of oral ciliature. (L) Macronucleus after protargol staining. (M) Oral ciliature. (N) Detail of infundibular polykineties. (O) T. obconica from Kahl (1933). (P) T. obconica from Kahl (1935). (Q) T. obconica from Bock (1952). (R) T. kamptostoma from Bock (1952) (synonym of T. obconica). (S) T. obconica from Biernacka (1963) (pos- sible misidentification). (T) T. obconica from Küsters (1974) (probably misidentified). (U) T. obconica from Shen & Gu (2016). EM1–2, epistomial membrane 1–2; G, germinal kinety; H, haplokinety; JM, junctional membrane; LB, lorica base; Ma, macronucleus; Po, polykinety; P1–3, infundibular polykineties 1–3; TB, trochal band; Val, valve. Scale bars = 100 μm (A, B, D); 50 μm (E–H, L, O–U).
