All paratypes are topotypes and were collected by J. Cassimiro, F.S.F. Leite and L.E. Lopes between 3–17 March 2005. 
DiagnosisDiagnosis: Phyllopezus diamantino is characterized by the following combination of character states: (1) Mental scales sub-triangular, with similar length and width and posterior margin not exceeding the second infralabial; (2) postmental scales increased, hexagonal, twice as long as wide, with broad contact each other and previously separated by about 1/3 of its length by the mental scale; (3) up to two scales in contact with the ventral margin of first infralabial; (4) presence of enlarged scales surrounding and separating postmental scales from the granules of the gular region; (5) six to seven infralabial scales; (6) granular scales in the distal region of mandible, juxtaposed, occasionally presenting tubercles of different sizes; (7) dorsal tubercles enlarged, corresponding to about six granular scales, elongated and keeled; (8) developed pollex; (9) cycloid or triangular scales around the auditory meatus, little bristly; (10) homogeneous scales of the same size in the region of the labial commissure; (11) many tubercles in the angular region between the upper and lower edges of the opening of the auditory meatus and eyes; (12) postcloacal pores always present in males and females; and (13) large sized, SVL 76.41–96.25 mm in males, and 72.38–82.36 mm in females. (DUBEUX et al. 2022) 
CommentBehavior: Phyllopezus diamantino is nocturnal and specimens were found on rocky outcrops and in tree and shrub trunks. Active animals were found only at night on the surface of rocks or trees or in rock crevices, and during the day only one inactive specimen was found under a rock. (Dubeux et al. 2022)

Sympatry: Gymnodactylus vanzolinii and Hemidactylus brasilianus were observed syntopically with P. diamantino on the rocks or in rock crevices, even though the new species was also found in other microhabitats as tree and shrub trunks. (Dubeux et al. 2022) 
EtymologyThe specific epithet “diamantino” is a latinized adjective referring to its type-locality, Parque Nacional da Chapada Diamantina, the northern segment of the Cadeia do espinhaço in the state of Bahia, Brazil.
