[1] Found in the Galápagos Islands, it was formally described as a new species in 2013 by lichenologists Frank Bungartz and Robert Lücking.

Redonographa galapagoensis was previously reported as Carbacanthographis saxiseda, but it was found to represent an undescribed taxon.

[2] The thallus of Redonographa galapagoensis is areolate and whitish gray, becoming yellowish white in the herbarium, with a smooth, epruinose surface.

The lichen produces norstictic acid, and the thallus turns K+ (yellow, then red), forming needle-shaped crystals under the microscope.

Its verrucose periphysoids have a different appearance from the spinulose surface found in Carbacanthographis, suggesting that the two genera are not closely related and do not have shared synapomorphies.
