Diagnosis

Reference	Diagnosis
C. E. Mitchell 1987	Rhabdosomes with narrow, asymmetrical proximal end and simple sicula; colonies may be biserial, uni-biserial, or fully uniserial. In biserial taxa the first two thecae are closely pressed to the sicula and lack mesial spines. Primitively, thecae are glyptograptid to climacograptid, but are modified to petalograptid, pseudoclimacograptid, or variously isolate, lobate, hooked, or triangular- particularly among the Monograptinae. Primordial astogeny is Pattern B, modified to Patterns H, I, or the monograptid pattern. Silurian representatives develop virgellar meshworks and ancorabased retiolitid colonies while others develop thecal and sicular cladia to re-establish multi-stiped, spreading colony forms.
M. J. Melchin et al. 2011	The first species within the clade that contains Monograptus priodon to develop a scandent, uniserial rhabdosome and all its descendants (Node 2, Figs. 2, 3).
