Angarozonium amurense — Mikhaljova 2004: 45–48, 46: figs 22–27, 47: map 3. Remarks. This species, originally described by Gerstfeldt (1859) from near the mouth of the Songari River, China as Platydesmus amurensis , then transferred first to Polyzonium (Mikhaljova 1979) and finally to Angarozonium , with the trans-Siberian Polyzonium cyathiferum Mikhaljova, 1981 as a junior subjective synonym ( Shelley 1998 ). Slightly later the formal synonymy was confirmed by the re-examination of samples of what might be considered as near-topotypes ( Mikhaljova 1998 ). This species appears to be widespread throughout the Asian part of Russia , including the northernmost known record of Diplopoda in Northern Hemisphere: Republic of Sakha, Yana River middle flow, ca 67˚40’N ( Mikhaljova and Marusik 2004 ). At present the species is known from Siberia (Krasnoyarsk Province, Irkutsk Area, Chita Area, Buryatia, Republic of Sakha (=Yakutia)), Russian Far East (southern part of Khabarovsk Province, Jewish Autonomous Region, Kamchatka Peninsula, northern and central parts of Sakhalin Island), Northeast China (near the mouth of Songari River) and Mongolia (environs of UlaanBaatar).
