Holotype ZPAL Ga.9/75 from the Early Valanginian (Early Cretaceous) of Wąwał; lateral and apical view, white arrow indicate demarcation between protoconch and teleoconch

Diagnoza

Protoconch having 2.25 smooth, low spired whorls and demarcated from teleoconch with thickened outer lip. Teleoconch higly conical with spiral rib ornamented by broad nodes situated close to the adapical suture. Nodose rib forming narrow adsutural platform.

Porównanie

Similar to Diatrypesis guerrei (Hébert & Eudes−Deslongchamps,  1860) but the latter differs in having opisthocyrtic axial ribs. Also, some species of Cimolithium are very similar to D. kurushini, especially Cimolithium eleanorae Allison, 1955 and Cimolithium aff. eleanorae Allison,1995.
