Fig. 43–49.

Leptopharynx bromelicola n. sp., somatic and oral ciliary pattern of macrostome (43–47) and microstome (48, 49) specimens after protargol (43–47) and Chatton–Lwoff silver nitrate (48, 49) impregnation. The width of the oral basket opening has strongly increased due to insufficient fixation (cf. Fig. 48, 57, 59, 63). 43, 45. Ventrolateral view of a specimen with very large oral basket recognizable by the nasse kinetosomes. The asterisk marks the triangular area between kineties 1 and 2. Figure 45 shows the adoral ciliature at higher magnification, especially the minute membranelle 1 consisting of only four basal bodies. 44, 47. Ventral views, where the preoral kineties are on the left side. 48, 49. The microstomes have the same ciliary pattern as the macrostomes, but are much smaller and have much less basal bodies. The arrow (48) marks part of the oral primordium. Scale bars = 5 μm (Fig. 46) and 20 μm (Fig. 43, 44, 47–49).
