Paraderma bogerti + Primaderma nessovi

(figs. 55E, 56D)

DIAGNOSIS: These taxa are united in the current analyses by 309(1) presence of grooves separating the osteoderms on the maxilla.

COMMENTS: Monophyly of Paraderma bogerti and Primaderma nessovi to the exclusion of all other squamates is not recovered in all of the principle trees in this analysis (see comments above and below), but the close relationship of these two taxa is recovered by the Adams consensus. Note, though, that the only unambiguous synapomorphy for this clade is homoplastic in that it also forms part of the diagnosis for the clade of helodermatids including Lowesaurus matthewi and Heloderma (below).
