Diagnostic Description

Adult morphology Snout-vent of about 30 mm or slightly more. No sex dimorpllisrn in size. Head as large as wide, ogival, with acutely rounded snout, distinctly protruding on the lower jaw. Nostrils laterally located, ridges just inside the choanae. Tongue moderate, subcircular, about 1/3 or 1/2 of the width of mouth opening. Eyes moderately prominent, laterally located. Tympanum visible, not distinct. A diagonal supratympanic fold, reaching beyond the axilla. Fingers slender, free, with strong blunt subarticular tubercles and round, moderate metacarpal tubercles. Rate of the finger lengths: I = IV = II-III. Toes free, slightly ridged laterally; subarticular tubercles conical and prominent. Small, sharp and conical metatarsal tubercles. A tarsal tubercle conical, evident, halfway between the inner metatarsal tubercle and the heel, being separated from the inner by a greater distance than the interval between inner and outer metatarsal tubercles. No tarsal fold present. When hindlegs is adpressed, heel reaches the eye; when the femurs are bent at right angles to body, the tibio-tarsal articulations overlap. Skin glandulous and granular dorsally, with two enlarged lateral ridges, brown-edged from the posterior eyelid down to the back. Short dorsal longitudinal glandular lines. A heavy ?-shaped glandular ridge. is often present between the shoulders. Ventrally granular, deep thoracic and discoidal folds present. Deep loose gular folds; a very heavy vocal sac in males extending across the throat. No inguinal glands; two small black-edged sacral glands distinguishable. Dark brown thumb pads in males during the spawlling. Color brownish or grayish on the dorsum, withdark enlarged longitudinaI spots or lines, according to a very variable pattern. The uniform, striped and ?-shaped patterns are thus prescnt. A distinct dark brown band from tip of snout, along canthus to eye, widening behind the eye and tympanum, downward and backward above the axilla and ending halfway to groin. Four vertical dark bands on the upper lip, the space between them whitish gray. Transverse brown bands on the limbs. Belly whitish, speckled with dark brown on throat and chest. Larval morphology The body is ovoid, the caudal muculature slightly entering onto the dorsal region. The tail is large, with high lanceolate dorsal fin, ending in an acuminate tip. The spiracle is sinistral, dorso-laterally located, in the posterior part of the body. The internarial interval is narrower than the interocular distance, being the nostrils closer to the eye than to the end of the snout. The cloacal opening is dextral, The larvae are faintly dark-colored dorsally, being paler in the last stages of development than in the early stages. Mouth show with lateral folds bordered by small close papillae; the parts of the upper and lower lips are bare. Horny beaks weak; tooth formula usually 2/3(1).

Habitat and Ecology

Habitat and Ecology
This is a widespread, nocturnal species that occurs in many habitats including open grassland, flooded savannahs, and pastureland. It breeds in cattle ponds or temporary waterbodies such as puddles, often in water-filled hoof tracks. The eggs are laid in foam nests, attached to grass stems at the margin of the pond. It is a very adaptive species.
