• Part 1, Oleg E. Kosterin, page 1-28: On the Odonata of North Kazakhstan Province. I. First data on Petropavlovsk Abstract: The fauna of Odonata of the environs of Petropavlovsk, North Kazakhstan, was for the first time examined on two short trips in late June and mid August 2015. Thirty five species were revealed. Coenagrion ecornutum was recorded in Kazakhstan for the first time, Gomphus vulgatissimus the second time and Stylurus flavipes the third time. Range expansion of C. ecornutum is discussed. Comparison is attempted of the known local Odonata faunas of the environs of Petropavlovsk, Omsk and Novosibirsk cities residing at the same latitude in the West Siberian Lowland. The Petropavlovsk fauna is very close to that of Omsk. The earlier published Kazakh records of G. vulgatissimus and S. flavipes are clarified and corrected. Breeding of Aeshna viridis in Ishim River (lacking water soldier) is supposed. Part 2, Oleg E. Kosterin, page 29-46: Odonata registered on a short excursion to Kyshtovka District, Novosibirsk Province, Russia Abstract: During a fourday trip to Kyshotovka District, the most northwestern district of Novosibirsk Province, 21 species of Odonata were recorded. Two significant findings were made: that of Coenagrion ecornutum is most northern in West Siberia, and that of Lestes macrostigma is perhaps the northernmost in its range. The latter species was found over small, shallow, freshwater pools along a roadside. The diversity of this species’ habitats in Siberia in comparison to its uniform habitats at brackish water in Western Europe is discussed.
