- Gyrogonites coniform to oval-coniform, 600–714 μm long, 571–629 μm wide, with the maximal width at slightly over the middle or sub-apex; apex broadly flattened, base contracted, coniform. Spiral cells depressed or bulged, with 7–8 spiral rings on the lateral view. The cells at the apex periphery become slightly narrow and thin; depression on the apical periphery indistinct, and cells on the apical centers widen and thicken, forming short quincunx enations. Bottom holes various, and the larger ones with external depressions.
