Coniophanes joanae is a species of snake in the subfamily Dipsadinae of the family Colubridae.

[2] The specific name, joanae, is in honor of Joan Wilson Myers, the wife of the describer.

[1][2] The preferred natural habitat of C. joanae is forest, at altitudes of 600–1,400 m (2,000–4,600 ft).

[1] C. joanae has only 17 rows of dorsal scales both at midbody and anteriorly.

[2] C. joanae is diurnal, and despite being a forest-dwelling species, it is terrestrial, not arboreal.
