S-chaetae can be grouped in four types (Fig. 4A), with chaeta S4 difficult to distinguish from type-5 mes. The S-chaetae formula observed in our species, as well as in other unidentified ones of the bidenticulati group, is 0/2,1/1,2,3,4,3,0 from head to Abd.VI (Figs 4-6), including 0/1,0/1,0,1,0,0 for S1; 0/1,1/0,1,0,0,0 for S2, 0/0,0/0,1,2,2,3 for S3 and 0/0,0/0,0,0,2,0 for S4.

Body chaetae of various types were detected and tentatively grouped in categories. The mes of type-5 are the most numerous chaetae dorsally. They are seen as smooth under microscope examination, but serrated under SEM, Fig. 4A5; distinguishing them from S4 sens is especially difficult on Abd.IV where both are present, and the same confusion may arise for many other

. As patterns of these mes as well as those of S4 sens seem to be stable inside population and different between species, further investigations will have to re-examine this character for its use in taxonomy.
