Description
Austrochaperina blumi has a relatively narrow head with a roundish blunt snout when viewed dorsally and slightly projecting when seen laterally. Nostrils are placed laterally and are barely visible when viewed dorsally. Loreal region is nearly vertical and shallowly concave. The canthus rostralis is rounded. The tympanum is small and indistinct with a horizontal diameter of the annulus smaller than one-half that of eye. The largest from the collected series is a gravid female reaching 26.3 mm SVL; the largest male reached 24.4 mm SVL and had vocal sac openings. Relative finger lengths are as follows: 4>3>2>1, all with grooved terminal discs; first finger’s disc is slightly wider than penultimate phalanx. Toes are unwebbed and have the following relative length formula: 4>3>5>2>1. Subarticular tubercles are small and rounded. The dorsum is smooth and has a slightly raised midvertebral line and a shallow fold from the posterior corner of the eye across the upper edge of the tympanum. Coloration of the head, body and limbs is that of a pale tan with many small darker irregular spots. Lips are pale with darker spotting. The lower parts of the thighs are patterned/colored like the dorsum. Soles are dark and unspotted.
