TypesSyntypes: NRM 5097, BMNH 1946.1.8.43 
DiagnosisDiagnosis: Philodryas erlandi differs from all congeners except P. mattogrossensis by a dorsal colour that shifts from green on the anterior half of the body to brown on the posterior part. Philodryas erlandi is distinguished from P. mattogrossensis by the absence of a well-marked dark green or brown dorsal stripe restricted to the anterior one- third of the body (vs present in P. mattogrossensis), pres- ence of a dark line on the supralabials (vs absent or less evident in P. mattogrossensis), dorsal formula usually 19–19–15 (vs usually 21–19–15 in P. mattogrossensis), and first temporal elongated (vs. as wide as high in P. mattogrossensis).

Distribution: see map in Cacciali et al. 2016: Fig. 11. 
EtymologyNamed in honor of Nils Erland Herbert Nordenskiöld (1877-1932), Swedish archeologist and anthropologist.
