J. J. Head 2020Aniliid snake possessing the following characters: neural spine consisting of low lamina with concave dorsal margin anteriorly connecting to a short, flat-topped, subtriangular process at the posterodorsal edge the neural arch; posterior edge of neural spine bifid; accessory ridges present lateral to the neural spine, terminating posteriorly at the edge of the neural arch, resulting in a roughly tricarinate posterior edge of the arch in dorsal view; posteromedian margin of neural arch thick and straight at posterior margins of neural spine and accessory ridges, posteromedian notch absent; centrum anteriorly wide; and anterior margin of zygosphene broadly concave.
