Original Description: Click to view


The following species are classified as members of subgenus Diacerion:



Pilsbry & Vanatta (1896:317) noted that axial and parietal folds are present, the latter very long and doubled, or short and interrupted, with an accessory denticle that is rarely obsolete.   They divided the subgenus(1896:326) into the Group of C. striatellum (Paracerion Pilsbry & Vanatta, 1895 + Tridentistrophia Maynard, 1896:9) [unfortunately, their usage of C. striatellum is incorrect and refers to a Cuban species], and the Group of C. rubicundum (Diacerion Dall).
