Dear All, I recently have been looking at some Clivina and would like to know the extent across the genus that the transverse sulcus occurs. The image below shows some typical ones and it seems that most all taxa have them. However, I can't find any summary statement published in the descriptions of the genus, subgenera or related genera that clarifies what species have and don't have these sulci. Do any of you know or know a paper that discusses this?
