List of Odonata species of Slovenia

The list of Odonata species of Slovenia includes 72 species of dragonflies and damselflies () for which reliable records exist from the present-day territory of Slovenia, including one that has not been seen since the 1960s and is presumed to have been extirpated (locally extinct), but could have simply been overlooked. The list is based on two reference works: "Atlas of the Dragonflies (Odonata) of Slovenia", a joint publication of the Slovene Odonatological Society and the Slovene Centre for Cartography of Fauna and Flora from 1997, and the newer "Atlas of the European dragonflies and damselflies" (2015), supported by other, more recent publications in which new species described after 1997 were documented.
Odonata species from the territory of present-day Slovenia were systematically studied by the naturalists Johann Weikhard von Valvasor and Giovanni Antonio Scopoli as early as the 17th and 18th centuries; however, the first systematic compendium was only published in the 1960s by the Slovene zoologist . The distribution of Odonata in Slovenia is now fairly well known by international standards, with Slovenia having been one of the first European countries for which a full account of faunistic data (an "atlas") was published. The number of species (72) represents almost exactly half of the European species (143) and is comparable with the number of species of Germany (81) and Spain (80), both much larger countries. Slovenian odonate fauna is therefore considered highly diverse, which is attributed to the country's position on the junction of several ecoregions where many species reach the border of their distribution.
The list.
Taxonomic order and nomenclature follow the "Atlas of the European dragonflies and damselflies" (2015), while "Atlas of the Dragonflies (Odonata) of Slovenia" is the primary source of the data, with notes explaining discrepancies.
Columns with scientific and vernacular names in English and Slovene are followed by conservation status as determined by the country's official "Red list of Odonata" ("Rdeči seznam kačjih pastirjev"). Categories of conservation status according to this list are as follows:
Most (24) of the species included in the "Red List" are also protected according to the newer "Ordinance on protected native species of animals" ("Uredba o zavarovanih prosto živečih živalskih vrstah") from 2004, which annulled the previous ordinance on which the "Red list" is based. The protected species are labelled with an additional asterisk (*), while the old "Red list" statuses are retained for reference.
Most species native to Slovenia are not globally threatened and are regarded least-concern by the International Union for Conservation of Nature (IUCN). There are two exceptions – both "Cordulegaster" species – that are near-threatened. Additionally, the southern damselfly ("Coenagrion mercuriale") is near-threatened as well, but that species is almost certainly extirpated.
Excluded species.
The Slovene "Atlas" mentions four additional species as records from older literature, but there is insufficient evidence for their presence so they are excluded from that list as well:
