open through one long or short duct, or through several slits or pores on dorsal side offemur medially or proximally.One species has been found in the Russian waters of the Sea of Japan. The Keyalso includes four more species which can be found in this region in future. The recordof Anoplodactylus inermis for Peter the Great Bay (Turpaeva, 2006) was made bymistake; as it turned out, that male specimen was collected not in the Sea of Japan, butin the Indian Ocean.KEY TO THE SPECIES OF THE GENUS ANOPLODACTYLUS1(2).

Trunk almost rounded, shield-shaped, unsegmented, without setae.Lateral processes contiguous proximally; each bears one tubercle with spine on distalmargin. Cephalic segment has short and narrow projection over base of proboscis.Ocular tubercle tall, conical, with "shoulders", situated a little distally from frontalmargin of cephalic segment, in its narrow part; eyes oval, pigmented. Proboscis twiceshorter than trunk, thick; its length slightly more than its diameter, noticeably broaderthan frontal part of cephalic segment. Abdomen short, thick, erect. Cheliforesrelatively long; scapes of both chelifores placed close to each other, reach somewhat125
