CLADISTIC ANALYSIS OF OCTOBRANCHUS MARION & BOBRETZKY, 1875 (TRICHOBRANCHIDAE: POLYCHAETA)

The genus Octobranchus contains nine valid species: Octobranchus pacificus (Berkeley & Berkeley, 1954), O. antarcticus Monro, 1936, O. floriceps Kingston & Mackie, 1980, O. japonicus Hessle, 1917, O. lingulatus (Grube, 1863), O. longipes Blankensteyn & Lana, 1987, O. myunus Hutchings &am...
