Bioacoustics of Capensibufo magistratus

Description of holotype . A male, 19.6 mm SUL, in breeding condition, robust, widest at mid-body; head wide (SUL/HW 2.6), not wider than trunk, as long as wide (HW/HL 1.1); snout long (SL/HL 0.4), bluntly rounded in dorsal view, angular in profile, slightly projecting beyond lower jaw, shorter than wide (SL/IO 0.73); canthus rostralis rounded; loreal region slightly concave; nostrils with a low rim, situated closer to tip of snout than eye (EN/SNO 1.67), separated from each other by distance about equal to distance between eye and nostril (IN/EN 1.07; eyes directed anterolaterally, relatively small (EYE/HL 0.38); eye diameter less than snout length (EYE/SL 0.77); a small angular umbraculum is present; interorbital distance less than eye diameter (IO/EYE 0.77), and greater than internarial distance (IO/IN 1.25; tympanum absent; choanae small, round, located far anterolaterally at margins of roof of the mouth; no vomer processes; median lingual process of tongue absent. Viewed from below the upper lip protrudes beyond the lower jaw. Lateral and dorsal surfaces of trunk smooth; ventral surfaces of limbs and gular smooth; parotid elongated, smooth, narrow anteriorly, (PL/PW 3.5), (PL/SUL 0.25); no distinct rictal gland behind angle of jaw; inguinal gland deeply corrugated, extending to level of anterior thighs; vent opens ventrally, small skin folds present but no large surrounding glandular structures. Fore limbs moderately robust; hand robust; tips of fingers rounded, without discs; relative length of fingers: III>I>II>IV (F3/HW 0.59); distal subarticular tubercle of finger 3 double, all subarticular tubercles well developed; two smaller supernumerary tubercles present on the palm; thenar tubercle flat; a single rounded metacarpal tubercle present. Nuptial pad present as a swollen base of the first finger with a raised glandular pad present on the dorsal surface. Foot equal to tibia (FT/TIB 1.01); Relative length of toes: I<II<V<III<IV; subarticular tubercles small, rounded; webbing absent; inner metatarsal tubercle rounded; outer metatarsal tubercle small, flattened. Colour in life. The dorsal background is grey, overlain with pale brown. There is a pale grey vertebral stripe. The dorsal warts are darker brown, surrounded by incomplete black rings with a thin yellowish outer border. Numerous small dark brown flecks are distributed across the back. The parotid is reddish brown. The iris has redbrown and silver speckles. The upper lip is grey. The throat is pale with a pinkish tinge. The belly is underlain with grey, with pink spots and black pigment concentrated along the midline. The inguinal gland is very dark red-brown, surrounded by pink spots. The undersides of the limbs are dark brown to black. Colour in preservative . The dorsal surface has many small brown dots with incomplete black margins, surrounded by a fine white border. There are a few brown-tipped warts within each brown dot. The parotids are brown, and there is a thin pale vertebral stripe. Ventral markings consist of minute white dots that merge to form pale marks laterally and posteriorly. The fingers and toes are dorsally pigmented, confluent with the dorsal pattern. Paratype variation. The paratype is a 23.7 mm SUL female. It is similar in body proportions to the holotype , but the umbraculum is rounded, there is a pink tinge to the inguinal patch, the vent opening has fleshy papillae, and the parotid is widest in the middle. Advertisement call. This species does not make an advertisement call but makes a distress call when disturbed.
