| Description | All the available published and unpublished distributional records of two endangered pond skaters, Gerris asper (Fieber, 1860) and Gerris lateralis Schummel, 1832 (Hemiptera: Heteroptera: Gerridae) in the Czech Republic are summarized and mapped. Gerris asper was originally described from Bohemia by Fieber (1860) without any exact locality and we have been unable to confirm its occurrence with any subsequently collected specimen. The distribution of G. asper in the Czech Republic thus seems to be limited to southern and central Moravia, with a single new record from northern Moravia, where it was found syntopically with G. lateralis. Gerris lateralis is widespread in Bohemia and a new species for Moravia, where it was collected on two sites in the north of the territory (the Czech Silesia). General distribution, biology and ecology of both species are reviewed and summarized. |
