Abstract

The trigonotarbid arachnid,Pocononia whitei (Ewing 1930), is redescribed and referred to the family Eophrynidae as the oldest known eophrynid. It suggests that trigonotarbids had diversified into the recognised Upper Carboniferous families by the Lower Carboniferous.

Kurzfassung

Die trigonotarbide ArachnidePocononia whitei (Ewing 1930) wird erneut beschrieben und als der älteste bekannte Vertreter der Eophrynidae zur Familie der Eophrynidae gestellt. Dies legt nahe, daß die Trigonotarbiden sich bereits während des Unterkarbons in die aus dem Oberkarbon bekannten Familien aufgespalten hatten.
