Only one penial seta per bundle is present in the fully mature specimen LISB 97.80.51, in contrast to the other two partly mature specimens where 2 penial setae per bundle are noticeable. As some other setal bundles nearby genital segments of the mature specimen have only one seta also, it seems likely that missing setae were lost, by accident or as a result of copulation, and that two penial setae per bundle is the common setal pattern.
