Locality and horizon: Daijiagou section; 4 th member of the Lungtan Formation.

Remarks.—This species is defined by its large size, subcircular to subtriangular outline, and robust plicae that are occasionally twisted. The Daijiagou specimen (NMV P309622) is identical in all observed aspects to the topotypes of Huang’s species described by Jin et al. (1974) from the Lungtan Formation of Guizhou, South China. Meekella megala Grant, 1993 from the Wordian of the Khios Island, Greece is indistinguishable in shell outline, size and low plicae from Huang’s species, however the Greek species can be differentiated from Huang’s species by its relatively lower ventral interarea and more flattened pseudodeltidium.
