Kreischeria wiedei Geinitz 1882 (Arachnida: Trigonotarbida) from the Upper Carboniferous (Westphalian D) of Zwickau, Germany is redescribed. The family Kreischeriidae Haase 1890 is reinstated and rediagnosed to accomodate this species. We provisionally refer the species Anzinia thevenini (Pruvost 1919), Gondwanarachne argentinensis Pinto & Hünicken 1980, Hemikreischeria geinitzi (Thévenin 1902), Pseudokreischeria pococki Gill 1924 and Pseudokreischeria varia Petrunkevitch 1949 to Kreicheriidae too.
