Explanation of Names
Hydroisotoma schaefferi (Krausbauer 1898)
Range
holarctic (NA & W.Palaearctic)(1), very common in Europe
Remarks
sexually dimorphic (quite rare in entomobryomorph Collembola): thickening of the outer side of the 2nd antennal segments is typical of males (Wray 1978) • adapted to life on water surface: head hypognathous (mouth directed to watersurface, typical for water surface film dwellers) • broad dentes prevent piercing the surface film when the specimen needs to jump. ―comments by Frans Janssens
