ABSTRACT Two new free-living marine nematode species of the genus Antomicron Cobb, 1920 belonging to the family Leptolaimidae are described from the seabed sediment of Jiaozhou Bay of the Yellow Sea. Antomicron holovachovi sp. nov. is characterised by loop-shaped amphideal fovea; male with five straight tubular and 41 alveolar supplements; short cephalic setae; slightly curved slender spicule with cephalated proximal end and tapered distal end; and rectangular gubernaculum with a short dorsal caudal apophysis. Antomicron chinensis sp. nov. is particularly characterised by loop-shaped amphideal fovea; male with only alveolar supplements, without tubular supplement; slender and slightly inverted S-shaped spicule with cephalated proximal end and tapered distal end; and rectangular gubernaculum with a slender dorsal caudal apophysis. An updated identification key to species of the genus Antomicron is also provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:D7DB980D-4BD5-4966-8756-D7FC2A46DAAA http://www.zoobank.org/urn:lsid:zoobank.org:act:C3142083-6B72-4797-BE50-F8FFC412ACE4 http://www.zoobank.org/urn:lsid:zoobank.org:act:5393CA61-1BE5-4F3B-88AA-501B36472A04
