CommentGeophis rostralis is not listed in the Zoological Record of 1864. There seems to be no reference to it in SMITH & SMITH 1976.

Synonymy: The status of the species is still uncertain. The species was originally described based on a color plate with no indication of a type specimen or locality. Various authors have recognized G. rostralis as a distinct species (Campbell et al. 1983), while others (Downs 1967) maintain that this species is conspecific with G. dubius.

Distribution: see map in CANSECO-MÁRQUEZ et al. 2016: 133 (Fig. 1). 
EtymologyNamed after Latin rostralis, pertaining to a rostrum, beak or snout. [?].
