Figure 4 in Morphology and phylogeny of three trachelocercids (Protozoa, Ciliophora, Karyorelictea), with description of two new species and insight into the evolution of the family Trachelocercidae

Figure 4. Trachelolophos binucleatus sp. nov. from life (A–E) and after protargol staining (F–I). A, typical individual; B, C, different body shapes; D, two macronuclei and one micronucleus forming a nuclear group; E, small cortical granules arranged in line between somatic kineties; F, G, infraciliature of anterior end, indicating circumoral kinety, ciliary tuft, narrow glabrous strip and bristle kinety; arrow in F shows anterior secant system on the left side of glabrous stripe; H, I, general infraciliature of the holotype specimen, to show single nuclear group, narrow glabrous stripe, bristle kinety and anterior secant system (arrowheads). Abbreviations: BK, bristle kinety; CG, cortical granules; CK, circumoral kinety; CT, ciliary tuft; GS, glabrous stripe; Ma, macronuclei; Mi, micronucleus; NG, nuclear group; SK, somatic kineties. Scale bars: 400 μm in A–C; 30 μm in F, G; 200 μm in H, I.
