Abstract
Numerous specimens of Chirocephaluswere found repeatedly over the last eight years in an intermittent lake in SW Slovenia. They were first identified as Chirocephalus spinicaudatusSimon, 1886. Later it turned out that they fit the diagnosis of Chirocephalus croaticus (Steuer, 1899), a species described from a small lake in Southern Croatia, about 300 km from Slovenia. It was considered as endemic of its type locality only. Now its range expands into NW direction. The population in Slovenia is in good condition and, if there is no change in land use, could persist for a long time. A small population of the same species in a small puddle near the intermittent lake Cerkniško Jezero (about 30 km from lake Petelinjsko Jezero) was destroyed a few years ago. A detailed description of specimens of both sexes is given and some information on their ecology is added. Particular attention is given to the male legs which could provide good diagnostic characters. For comparison, legs of Chirocephalus diaphanus Prévost, 1803 are shown.
