DistributionS/SW Brazil (Minas Gerais, Rio Grande do Sul, Goiás, Bahia),
NE Argentina (Buenos Aires, La Pampa, Santa Fe, Entre Rios, Chaco, Misiones, Santiago del Estero, Corrientes, Córdoba, San Luis, Rio Negro, Mendoza), Uruguay, S Paraguay

Type locality: "Uruguay" [in error], corrected to Paraguay (fide original data tag and MCZ Catalogue, cited in Wallach et al. 2014).  
TypesSyntype: MCZ R-870, a 154 mm, juvenile male, and MCZ 177823, a 347 mm male both collected by Jefferies Wyman, November 8, 1861. 
DiagnosisDiagnosis (genus): (apomorphies followed by ‘*’): head, body, and tail uniformly reticulated gray or brown, with anteriormost edge of ventrals being green coloured*; lack of deep body calyces on the proximal half of the asulcate surface of the hemipenial body*; lateral enlarged spines; distal rows of middle sized spines disposed in a typical “V-shape” configuration on the asulcate surface of the hemipenial body*; diameter of the middle of the hemipenes larger than both proximal and distal extremities; dorsal scale rows reducing anterior-posteriorly from 19 to 13 or uniformly in 13e13 in Pseudablabes agassizii; low number of ventral scales (130e184); seven supralabials; body with dorsolateral stripes and short tail (MELO-SAMPAIO et al. 2020). 
CommentSynonymy after CEI 1993.

Habitat: partly arboreal (Harrington et al. 2018).

Type species: Eirenis Agassizii JAN 1863: 260 is the type species of the genus Pseudablabes BOULENGER 1896. Note that Callirhinus has priority over Pseudablabes following the provisions given in the article 23 (ICZN 1999), but is preoccupied by Callirhinus Blanchard, 1850 (Coleoptera, given as 1851 by Williams & Wallach 1989), hence Melo-Sampaio et al. 2020 proposed the resurrection of the genus Pseudablabes for the clade containing Pseudablabes agassizii.

Phylogenetics: MELO-SAMPAIO et al. 2020 tentatively included arnaldoi within Pseudablabes (based on morphology) although they did not have any molecular data. Note that Arredondo et al. 2020 could not replicate the monophyly of Pseudablabes as defined by Melo-Sampaio et al., hence we reverted them to Philodryas. 
EtymologyNamed after Louis Agassiz (1807-1873), Swiss zoologist. See Bastos & Sa 2011 for further biographical details.
