Two new free-living nematode species of Setosabatieria (Comesomatidea) from the East China Sea and the Chukchi Sea

Abstract

Two new free-living marine nematode species of the genus Setosabatieria from the sandy intertidal zone of Xiamen, in the East China Sea and a shallow water area in the Chukchi Sea, Arctic Ocean are described and illustrated. Setosabatieria longiapophysis sp. nov. is characterized by four longitudinal files with 7–9 cervical setae per file, 15–16 minute papillate precloacal supplements and relatively long straight apophyses of gubernaculum. Setosabatieria major sp. nov. is identified by its relatively large body of 2701–3144 µm, the number (10–11) of cervical setae per file, 26–28 minute papillate precloacal supplements and spicules with a central septum at both the proximal and distal end. A pictorial identification key to all known species of Setosabatieria is provided.
