In Hungary it was known from Aggtelek, Lesenceistvánd, Nagykovácsi, Orfú, Szemere, Szuhafő and Zádorfalva (ÁDÁM 1992, CSABAI and MÓRA 2002, CSABAI et al. 2004, MERKL 1999). It occurs in small water bodies, in springs or spring-fed streams, in most cases in moss or decaying leaves. Agabus striolatus (GYLLENHAL, 1808) - It is a rare Central and North European species, occurs mainly in southern boreal and temperate zones. It is known from France and Great Britain to Moscow. In Hungary the species was found in only a few localities: Badacsonytördemic, Barcs, Lakitelek, Tabdi, Farkasfa, Kaposvár, Kéleshalom, Mosonmagyaróvár, Pocsaj, Orfű, Szeged and Zalaszántó (ÁDÁM 1986, GIDÓ and SZÉL 1998, HORVATOVICH 1981a, 1981b and unpublished data).
