It is found in the upper Amazon Basin of southeastern Colombia (Amazonas Department[4]), Ecuador, Brazil[1][3][5] and Peru.

[3] The specific name dorisae honors Doris Mable Cochran, an American herpetologist.

[2][6] The dorsum is bright green with small dark spots[2] or lavender green with small spots that are white to yellow.

[6] Sphaenorhynchus dorisae is a semi-aquatic species that inhabits open permanent and semi-permanent bodies of water such as ponds, large lakes, and flooded meadows at elevations of 40–300 m (130–980 ft) above sea level.

They are commonly found amidst floating vegetation, in particular water lettuce (Pistia).
