Macrobiotus ariekammensis Weglarska 1965

Macrobiotus ariekammensis (Figures 4C, 5B, D) Characters previously not cited in descriptions of M. ariekammensis and/or M. adelges (Węglarska 1965; Dastych 1977, 1985) are: cuticular pearls over the entire surface of the animal, larger pearls in anterior (mainly around the mouth opening) and caudal dorsal regions; buccal tube with a clear bend in an anterior position (immediately behind the mouth opening). At this level, the animal has a large dorsal tooth on the internal surface of the buccal tube (Figure 5B, D); in lateral view, the ventral portion of the buccal tube is shorter and ends at the level of the stylet sheaths; ventral lamina has a wide ventral crest characterized by two lobes in lateral view (Figure 5D). Contrary to that reported by Dastych (1985), the buccal armature contains a posterior band of small teeth (transverse crests absent).
