Dr. Ju-Shey Ho from California State University, Long Beach thinks it might be new to science and needs additional material for a description. Anyone having polychaetes (all species) with parasitic copepods, please bring them to the next meeting. (Dr. Ho would probably appreciate any parasitic copepods'!).

Posteriorly they are much shorter" (Figure 3). (Banse and Hobson, 1968, pg 13). - although this is a good character of Micropodarke dub la , other hesionids may also possess these lobes.
