? 2003 Microdiptera uralensis (DOROFEEV) MAI ; Teodoridis, p. 22, pl. 5, fis 17, 18, 21, pl. 6, figs 9-11 (Hrádek/N., drill cores).

For the description and relationships see Holý (1978a, as Mneme donata ).

D i s c u s s i o n: According to Mai (in Mai and Walther 1978) the fossil genus Mneme EYDE is synonymous with Microdiptera CHANDLER ; hence a newly proposed combination is required. The seeds described from the drill cores Hr 42 and Hr 44 at Hrádek/N. by Teodoridis (2003) show a transitional character in their size (L/W index 1.15-1.71). This allows the assigning of this material to M. donata (L/W index 1.1–1.5) and M. uralensis (1.55–1.92). However, the number of longitudinal rows of polygonal cells on the germination operculum is more numerous (8–12) than in the type material from the Kristina Mine ( Holý 1978a).

M a t e r i a l: Ca. 75 seeds, G 3080, 3081, 4289-97, 4351, 4367-78, 4599.
