General distribution: Northern, southern Italy ; Italian, Austrian Alps; Central, South Europe, southwestern Palaearctic; Mediterranean. Habitat preferences: primarily praticolous. Remarks: Body length 650–690 µm. The morphological characters of the examined specimens correspond to the redescription of Weigmann & Schwalbe (1994) . A difference is the smaller body length ( Weigmann & Schwalbe 1994: 730–780 µm; Pérez-Íñigo 1997: 725–850 µm; Weigmann 2006: 725–850 µm). The known body length covers a wide range of sizes, the specimens from the Maritime Alps are only slightly smaller and are considered to be conspecific.
