The present state of knowledge of true bugs (Heteroptera) in the Protected Landscape Area of Poodří (Czech Republic)

Abstrakt: During 1995–2000 (most intensively in 1999), a faunistic survey of true bugs (Heteroptera) was carried out in the Protected Landscape Area (PLA) of Poodří. A special attention was paid to water bugs but terrestrial habitats were studied as well. In the area of the PLA and its closest vicinity, 225 species of bugs (27.1% of all species of the Czech Republic) belonging to 26 families were documented. Among water bugs (Nepomorpha and Gerromorpha) we found 36 species, i.e. 59.0 % of all species occurring in the Czech Republic. Three species (Sigara iactans Jansson, 1983, Phytocoris nowickyi Fieber, 1870, and Psallus mollis (Mulsant et Rey, 1852)) are new for the Czech Republic, one (Dicyphus epilobii Reuter, 1883) is new for Moravia. Two species, Acalypta carinata (Panzer, 1806) and Psallus flavellus Stichel, 1933, are reported from Moravia for the second time, and the occurrence of three species (Notonecta lutea Müller, 1776, Notonecta maculata Fabricius, 1794, Pinthaeus sangunipes (Fabricius, 1787)) is confirmed in Moravia after more than 40 years. Notes on diagnostic characters of Sigara iactans Jansson, 1983 are given and its taxonomic status is discussed.
