Vomerine teeth present. Posterior part of the tongue free and forked. Toes webbed. Omosternum and sternum ossified. Pupil of the eye horizontal. Snout more or less terminating in a point. Male with internal guttural vocal sacs. Shin (knee to ankle) shorter than body by 1.9-2.6 times. When the shins are positioned perpendicularly to the body axis, the heels contact or overlap. When the hind leg is stretched along the body, the tibio-tarsal articulation usually reaches the eye, nostril, tip of snout or even slightly exceeds it. Inner metatarsal tubercle high, shorter than the first toe by 1.1-2.3 times. Flank and thigh skin smooth. Dorsal coloration grey, light-olive, brown, yellowish or rufous. Chevron-shaped (^) dark glandular spot on the neck. Dark spots of 1-3 mm on dorsal and lateral surfaces vary considerably in number, arrangement and size. Temporal spot large. Light middorsal band with regular edges frequently present, often reaches the middle or the tip of the snout. Belly white or yellowish without pattern or with pallid-brownish or greyish spots on the throat and chest. Male differs from female by having nuptial pads on the first finger, paired guttural vocal sac and, during the breeding season, light-blue coloration of the body (the female is brown or rufous). Subspecific differentiation needs further study. The species belongs to the "brown frog" group.
