Distribution: Palaearctic, Greenland; East Asia, Australia Habitat: mainly forest soils

Obergurgl area: pine forest at 2050 m (Zirbenwald) Remark: In the previous studies Brachychthoniidae   have also been recorded at higher altitudes of Obergurgl. Verachthonius laticeps Strenzke, 1951   (sub. Brachychthonius laticeps   ), Liochthonius lapponicus (Trägårdh, 1901)   and Liochthonius sellnicki (Thor, 1930)   have been detected on Liebener Rippe in abundances of 300 to 600 individuals per m 2. In this study, species of this family were found only in minor   quantity in the pine forest (2050 m a.s.l.). Some taxa of the family Brachychthoniidae   (especially several species of the genera Liochthonius   and Verachthonius   ) are known to occur in raw soils in high abundances (Schweizer 1956; Moritz 1976; Schatz 2004). Most probably the absence of Brachychthoniidae   on Liebener Rippe in 2010 is referable to a change of the soil from raw soil to a later successional stage.
