Bioacoustics of Capensibufo rosei

Diagnosis. There is no tympanum in C. rosei , which distinguishes it from C. tradouwi and C. deceptus . In preservative, the dorsal spots in C. rosei have a brown centre, surrounded by incomplete dark rings. Capensibufo deceptus and C. tradouwi lack a thin outer white ring. Capensibufo magistratus and C. selenophos have incomplete black rings with a thin white outer ring. The umbraculum is rounded, while C. deceptus and C. magistratus have angular umbracula. The parotid is widest in the anterior third, which distinguishes it from C. magistratus , C. selenophos and C. tradouwi . There is usually no vertebral stripe in C. rosei while the other species have thin to broad pale vertebral stripes and/or bands. The belly is immaculate to lightly speckled, while C. tradouwi has flecks on the belly that may fuse to form short lines; C. magistratus and C. selenophos have white spots on a darker background. The ratio of parotid length/SUL is over 0.18, which distinguishes it from C. tradouwi , which has a ratio less than 0.18. The intraspecific uncorrected p distances for 16S are 0–0.4 (n=12), and 2.6–4.0 between C. rosei and the other three species previously included in this species, and 2.4–4.5 from C. tradouwi ( Table 1 ). In life the frogs are sometimes very dark, and pattern elements are difficult to discern. Advertisement call. This species has no advertisement call and makes no distress call when disturbed.
