Specific observations using scanning electron microscopy reveal short and slightly thick gouge sensilla on the antennomeres (Fig. 1 a); tergites: dense microdenticles with rosette glands along with well-barbed macrosetae; thick and well-barbed marginal setae, in addition to clothing setae with one or two distal barbs (Fig. 1 b-f).

A soil-dwelling species that is only occasionally found in caves (Silvestri 1931; Bareth and Condé 2001). It is distributed throughout the Carpathians Mountains (Ionescu 1955; Rusek 1964), and extends southward into the Balkan Mountains (Paclt 1969; Blesić 1984; 2000 a).
