Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. J. Cuerda et al. 1988 | Diplograptid sensu lato, characterized by pronounced genicular hoods which in profile views of the rhabdosome give the thecae a strongly hooked appearance, especially in the proximal thecae; ventral thecal margin introverted and strongly overgrown by genicular hoods; supragenicular wall convex; thecae approximately pseudoclimacograptid; median septum complete, gently undulating to straight, but probably not zig-zag. |
