Austrochaperina blumi is a species of frog in the family Microhylidae.

[3][4] The specific name blumi honors J. Paul Blum,[2][5] the herpetologist who collected the type series.

The dorsal surfaces of the head, body, and limbs are pale tan scattered with many small, somewhat darker, irregular spots.

The ventral ground color is pale tan, approaching white, but bearing numerous small, slightly darker spots on the throat and chest and fewer spots on the abdomen.

[2] Austrochaperina blumi occurs in disturbed habitats, including villages, lawns, and rural gardens, and presumably also in forests,[1] at elevations of 340–1,840 m (1,120–6,040 ft) above sea level.
