The morphology and infraciliature of the marine hypotrichous ciliate Holostichanagasakiensisi sp. nov. from the coastal waters of Nagasaki, Japan are described based on living and protargol-impregnated specimens. The new species is characterized by: medium-sized marine Holosticha,in vivo 100–150×30–40 μm with elongated body shape and slightly greyish to reddish cell colour; cortical granules arranged in conspicuously longitudinal rows; 24–32 adoral membranelles; ∼20 midventral cirral pairs and 7–10 transverse cirri; 28–42 left and 25–38 right marginal cirri; constantly 4 frontal cirri and 3 dorsal kineties; 23–63 macronuclear nodules.
