Phrynobatrachus dispar is a miniature (snout–vent length < 25 mm) species of puddle frog endemic to Príncipe Island in the Gulf of Guinea. Members of this genus are identified by the presence of a midtarsal tubercle, elongate inner metatarsal tubercle, and outer metatarsal tubercle. Numerous prominent asperities are present on the dorsum, and contrasting coloration includes dark barring on the thigh and leg. Scapular glands are present, forming a broken X-shaped pattern. Tympanum is indistinct, measuring less than half the width of the eye. Ventrum is pale cream-colored and clear except for the throat and a few darkly pigmented spots extending along the flanks to just beyond the front legs and distinct dark brown bars lining the lower jaw. Undersides of the hind limbs are a clear, slight yellowish hue. Like all Phrynobatrachus species, P. dispar lacks manus webbing; pes webbing is absent or extremely rudimentary and distal phalanxes are T-shaped, resulting in the appearance of dilated toe tips (Uyeda, Drewes, and Zimkus, 2007).
