Overview of the Zoogeographical Distribution of Aquatic and Semi-Aquatic Heteroptera (Hemiptera) in Turkey

The aim of this study is to review the faunistic and systematic studies on aquatic and semi-aquatic Heteroptera of Turkey and to make an analysis on the distribution and zoogeographically of the Turkish fauna. In this study, one species of Enicocephalomorpha, one species of Dipsocoromorpha, 51 species in 13 genera of Gerromorpha, four species in three genera of Leptopodomorpha and 55 species in 19 genera of Nepomorpha are reviewed. In total, 112 species belonging to 37 genera of five Infraorders are discussed from Turkey. Besides, all specimens were collected between 2009 and 2018 by the auther and the specimens deposited in the Nazife Tuatay Plant Protection Museum (Ankara) were also included in. It was determined that 94 species are distributed from Mediterranean, 57 species from Europe-Siberia and 90 species from Irano-Turanian. It was determined that nine species and subspecies comprising 8% of Turkish aquatic and semi-aquatic Heteroptera are endemic are located in Turkey. In addition, new locality records are given for the species that have been collected and diagnosed. Species composition, diversity and proportion of endemism varies considerably among the zoogeographic regions of the country.
