Zinovjev, A. G. & Schmidt, S. 1994: Amauronematus compactus Bogacheva and A. harpicola Bogacheva (Hymenoptera, Tenthredinidae) from the Polar Urals.- Entomol. Fennica 5:135-138.

In a list of from the Polar Urals, I. A. Bogacheva briefly described and named the larvae of two Amauronematus species attributed to Zhelokhovtsev. Reared specimens with Zhelokhovtsev' s identification labels can be considered syntypes. Lectotypes of Amauronematus compactus Bogacheva, 1977 and A. harpicola Bogacheva, 1977 are designated and described.

From 1970 to 1974 several species were lectotypes of Amauronematus harpicola Bogacheva collected and reared by I. A. Bogacheva at a and A. compactus Bogacheva, and describe them in biological field station in the northern Ob river this paper. We do not discuss the taxonomical posi­ region, Polar Urals.
