dc:description"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.
