Antenna (Fig. 11C): first endopod segment lacking inner 

 seta, second segment with 2 inner setae of unequal lengths 

 subterminally and 5 setae and 1 setule terminally; exopod 

 indistinctly 8-segmented, setal formula 0,1,1,1,1,1,0,3.

 which bifid at tip; the medial part of gnathobase is damaged 

 and it is not known whether or not a tuft of setules is present.
