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
