The microspore genus Simozonotriletes is reinterpreted in the light of new material obtained from three horizons in the Westphalian sequence of Great Britain. The spores are assigned to nine varieties of the type species Simozonotriletes intortus (Waltz). The species S. sublobatus (Waltz) is reduced to varietal status; Triquitrites trivalvis (Waltz) is transferred to Simozonotriletes and also recognized as an infraspecific category. The variation in the spore assemblages is described and the stratigraphical occurrences noted.
