The Mozambique ridged frog (Ptychadena mossambica, also known as the broad-banded grass frog, Mozambique grass frog, Mozambique grassland frog, or single-striped grass frog) is a species of frog in the family Ptychadenidae. These frogs can swim fairly well, jump far and can crawl with ease through dense plants. Their strong hindlegs can launch them up to three metres into the air in a single bound. Taxonomy Named after Mozambique where the species was first identified. Conservation status Not threatened. Description Length: 45–50 mm, maximum 53 mm Body Internarial distance greater than snout-nostril distance. Above Dark grey-brown to chocolate brown or green. A broad creamy to orange-brown vertebral band from snout to vent, bordered by elongated blackish spots. Snout without prominent pale triangle, not paler than rest of body. 6 or more dorsolateral skin ridges prominent, continuous only as far as the hump of the back and creamy-white. Dark brown blotches, smaller than eye, between vertebral bands and dorsolateral ridges. Tympanum Prominent. Slightly smaller than eye. Underside Creamy-white, sometimes with grey mottling along lower jaw on throat and on hind part of abdomen. Thighs and groin often pale yellow. Skin smooth. Forelimbs Arm comparatively short. Hindlimbs Foot shorter than tibia. There is a pale line sometimes present along the upper surface of the tibia. Back of thigh dark grey, with yellow mottling sometimes forming irregular lines. Webbing moderate. 2,75 to 3 phalanges of fourth toe and one phalanx of fifth toe free of webbing. Tarsal fold present. Inner and outer metatarsal tubercles present. Row of tubercles under fourth toe. Sexual dimorphism Gular slits in male not parallel to jaw-line on lateral view. Key identification points Back of thighs with yellow mottling, sometimes forming irregular lines (distinct from P. subpunctata, P. taenioscelis and P. guibei). Internarial distance greater than snout-nostril distance (distinct from other species except P. guibei, P. mapacha and P. schillukorum). Length of foot less than tibia length (distinct from P. guibei, P. mascareniensis, P. subpunctata and P. taenioscelis). Pale line on tibia sometimes present (distinct from P. anchietae, P. oxyrhychus, P. schillukorum and P. taenioscelis, although sometimes present also in P. subpunctata). Outer metatarsal tubercle present (distinct from other species except P. guibei, P. mapacha and P. schillukorum). Broad pale band extends from rump to snout but snout not paler than the rest of the body (distinct from P. anchietae, P. oxyrhynchus, P. schillukorum and P. subpunctata). Mottling on
