The data is in the strata
Note that the common species formerly known as D. multisecta and D. meeki are now placed in the new genus Cincinnetina.
All three species listed below likely belong to Heterorthina, according to Dr. Jisuo Jin, who is currently studying these species. Heterorthina can be recognized based on the presence of a dorsal medial groove or medial interspace (as opposed to a medial rib) and a prominently trilobate cardinal process. These species have not yet been formally assiged to Heterorthina.
