DistributionSE Brazil (Sao Paulo, Santa Catarina, Espirito Santo, Rio de Janeiro, Paraná)

Type locality: Curitiba, Estado do Paraná, Brazil [Rhadinaea beui PRADO 1943]

Type locality: Rio de Janeiro  
Reproductionoviparous 
TypesHolotype: MCZ 19345; MCZ 436 may be old catalog number, not found, probably lost fide Barbour and Loveridge 1929: 297, also cited by Myers 1974) 
DiagnosisDIAGNOSIS: Rhadinaea persimilis is small-headed and evidently diminutive member of the brevirostris group and agrees with R. affinis, R. bilineata, and R. poecilopogon in having 17-17-17 scale rows and a dark line on row 4 (or dark sides up onto row 4). It lacks the conspicuous white line that extends along the canthus rostralis and through the top of the eye in bilineata and poecilopogon, and it lacks the wedge-shaped postocular marking that characterizes affinis. Additional comparisons are given in the Remarks section under R. affinis. (Myers 1974: 212)
