|---|---|---|
| C. E. Mitchell 1987 | Species with glyptograptid to climacograptid thecae having relatively narrow geniculum and nearly straight supragenicular wall; proximal end generally narrow and fusiform, with strongly alternating thecae; generally septate with straight median septum and th21 or some later theca dicalycal, but may be aseptate; sicula simple, generally short and broad, lacking antivirgellar spines. | |
| M. J. Melchin et al. 2011 | The partial clade that includes the first
species that acquired a unistipular (aseptate) biserial rhabdosome in the clade that contains Paramplexograptus madernii and Retiolites geinitzianus and its descendants, but excluding the taxa included in the Subfamily Retiolitinae. |
