Comment
Wilkinson and Nussbaum, 2006, In Exbrayat (ed.), Reprod. Biol. Phylog. Gymnophiona: 49, 64, diagnosed the taxon and suggested that Grandisonia might be paraphyletic with respect to Hypogeophis and that this group is the sister taxon of Praslinia. on the basis of sparse taxon sampling San Mauro, Gower, Müller, Loader, Zardoya, Nussbaum, and Wilkinson, 2014, Mol. Phylogenet. Evol., 73: 182, found Grandisonia to be the sister taxon of Hypogeophis. Dubois, Ohler, and Pyron, 2021, Megataxa, 5: 269, 470, suggested on the basis of weak molecular evidence (Hypogeophis brevis forming the sister taxon of Grandisonia with low statistical support to the exclusion of Hypogeophis rostratus) that Grandisonia renders Hypogeophis paraphyletic and they placed Grandisonia into the synonymy of Hypogeophis.
