Diagnosis
ReferenceDiagnosis
C. E. Mitchell 1987Species 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. 2011The 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.
