(Figures 1 below and 2 above)
Reference specimen: AAG-UFU 4146 (Figure 1 below right), a topotype from the municipality of Rio Grande da Serra (around 23o44’21’’S, 46o23’02”W, 760 m above sea level), state of São Paulo, Brazil. Adult male 45.0 mm SVL. Proportions (%) in relation to SVL are: head length 38, head width 35, tympanum diameter 6.6, eye diameter 10, thigh length 63, shank length 52, foot length 62. Snout pointed from above and in profile; nostrils closer to tip of snout than to eyes; canthus rostralis smooth rounded; upper eyelids smooth; tympanum about 70% eye diameter; vocal sac single, subgular; vocal slits present; vomerine teeth in two straight transverse series, almost contacting medially, between and just posterior to choanae; finger lengths II<IV<I<III; finger tips rounded, not expanded; fingers without webbing, fingers II and III with weak lateral ridges, absent on fingers I and IV; basal subarticular tubercles distinct in fingers II, III, and IV, one distal tubercle distinct on fingers I and III; inner metacarpal tubercle oval; outer tubercle circular, double the size of the inner; no asperities on thumbs; no prepollex; no dermal fold on outer forearm; outermost lateral dermal fold from eye to groin; enlarged gland at angle of jaw; three distinct and plus two barely defined and discontinuous dorsolateral folds per side; dorsal texture smooth; dorsal surface of shank with 3–4 discrete longitudinal skin folds; flanks slightly glandular; belly smooth; belly disc fold distinct; a granular seat patch under thighs; toe lengths I<II<V<III<IV, tips slightly pointed, without webbing, or lateral ridges; inner and outer metatarsal tubercles oval, outer about 1/3 the size of inner; heel smooth; inner fold of tarsus barely distinct, 7/ 8 the length of tarsus; outer tarsus and sole of foot smooth.
Color in preservative: Back and flank patterns dark gray with darker spots; a broad light mid-dorsal stripe from mid head to vent; second and most lateral pairs of dorsolateral folds whitish; upper limbs with thick irregular mottling; border of lower jaw gray mottled; longitudinal skin folds on dorsal surface of shank whitish; belly whitish.
Color in life: Vertebral stripe light yellow, narrowed from mid head to snout tip; two most medial dermal folds dark gray, the two outermost whitish-yellow, as is the tympanic ring; dark gray stripes between folds and on dorsal surfaces of legs and arms; whitish belly, throat and vocal sac; yellowish on flanks; dark small mottles on throat sides; hidden portions of legs with dark irregular cells on a dark yellow background; bronze iris and black pupil.
Advertisement calls (Figure 3): A fast (0.03– 0.04 s) whistle given at a rate of 24/min.; 1–3 pulses distinguished in the spectrogram, pulse length diminishing from the beginning to the end of the call; frequency ranging between 1500 and 2500 Hz; dominant frequency between 1800–2400 Hz; call lacking harmonics.
Habitat and behavior: Males called from human altered habitats such as fallow plots in urban areas covered by short (<1m tall) grass-like vegetation. Males call from within underground chambers (N = 2) or exposed (N = 3).
