Within the P. bastardi species complex, the P. guibeae lineage from Tranoroa has been recovered as the sister taxon to Paroedura manongavato.

[7] However, Miralles et al. (2021) criticized the use of the species name P. guibei, as this emendation is incorrect from a nomenclatural perspective according to the articles of the ICZN.

While Guibé's ground gecko is known to occur syntopically with the related Paroedura rennerae at least in one site (Zahavola in Isalo), the latter species has a preference for more humid microhabitats.

[3] Enlarged, keeled scales are present on the dorsum (including on the dorsal surfaces of the limbs), arranged in regular longitudinal rows.

[2] Banded patterning is present on the digits of this species, a feature absent in the related Mocquard's Madagascar ground gecko and Paroedura rennerae.
