ABSTRACT. In 2020, Orthetrum brunneum (Fonscolombe, 1837) and Sympetrum depressiusculum (Selys, 1841) were first recorded for Novosibirskaya Oblast as photographic observations in the iNaturalist internet platform. Their populations and habitats were examined in situ. The habitat of O. brunneum at the Eltsovka Vtoraya River in Zaeltsovksiy Park in Novosibirsk lacked other lotic Odonata as a result of pollution. Supposedly the river inside the city limits is warm enough during winter to make possible its colonisation by O. brunneum far to the north of its main range. The record of S. depressiusculum (Selys, 1841) at the Obskoe Water Reservoir is the northernmost in Siberia. A list of 57 Odonata species currently known from Novosibirskaya Oblast is also provided.
KEY WORDS: Odonata, dragonflies, Orthetrum brunneum, Sympetrum depressiusculum, West Siberia, Novosibirsk Oblast’, first record, water pollution.
