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.
