CommentStenocercus dumerilii, S. tricristatus, S.quinarius, and S. squarrosus share combined morphological features (three or five dorsal crests, enlarged post-supraciliary scale, head blunt, pyramidal, bordered by supraciliary crests) unseen in the remainder of the genus (see Avila-Pires 1995, Nogueira & Rodrigues 2006).

Type Species: This is the type species of the genus Ophryoessoides.

This species is known only from a single specimen.

Map: see TEIXEIRA et al. 2015: 417.
