Greetings:
A few years ago I encountered specimens of Eteone from local So California
sediments that had antennae with weakly "articulated" appearance(3-5 joints).
Upon compound scope examination, small tufts of "sensory fibers" could be seen
originating at each of these weak articulations. Some specimens appeared to
show this condition more clearly than others, and is assumed to be due to
contraction effects. Like many minor morphological conditions, its not
obviously apparent unless you are looking for it specifically....then you can
see it on many specimens.
bye for now,
