Wetzeliella distalis
Wetzeliella distalis He Chengquan, 1991
Holotype: He Chengquan, 1991, pl.41, fig.7
Age: Middle Eocene
Description from He Chengquan, 1991, translated by Suning Hou, 07-01-2019
Description: The cyst is dorsal-ventral flattened, contour pentagonal, with a distinct horn developping at each corner. The specimen is poorly preserved, an apical horn is broken; Both lateral horns are well developed, 15μm long, with short spines at the end; Two horns are strong and unequal in size, conical, the larger one is broken, the smaller one is 20 μm long, quite far from each other (about 55μm). The cingulum is only marked by a groove in the lateral horns. The outer wall surface has sparse rod-like processes, processes straight or curved, some of them are solid, others gradually enlarged near the base and hollow, varying in length, length 3-7.5μm. The surface of the processes and the outer wall is nearly smooth. Inner body contour rounded pentagonal, surface smooth; It is close to the outer wall, except at the horns, generally the outer cavity width 0.5-2μm. The archeopyle intercalary, slightly wide trapezoidal outline. The operculum isr completely separated and preserved in situ. The cyst (incomplete) length is larger than 110μm, width larger than 102μm; Iinner body length 80μm, width 85μm. Comparison: The new species differs from Wetzeliella articulata in the long distance between 2 antapical horns, inner body round pentagonal rather than oval and sparse processes; It differs from W. pentagona (Vozzhen.) in longer and sparse processes, no bifurcate distally etc .
