The rough frog (Ranoidea verrucosa), also known as the woodland water-holding frog, warty water-holding frog, and red-backed cyclorana, is a species of treefrog native to northern New South Wales and south-eastern Queensland, Australia.[3][4][5][6][7]
The rough frog was originally described as Cyclorana verrucosus by Tyler and Martin in 1997,[2][3] and later placed in the genus Litoria.[3]
The rough frog is a medium-sized burrowing frog. Male frogs reach between 35–45 mm in body length and females are slightly larger at 37–49 mm in length.[5][6]
This stout frog is typically grey-brown to olive brown in colour.[4] Its back is irregularly marked with dark green spots on a tan background, or black/dark grey on a pale brown background.[5][4] Both colour variations have a thin pale cream coloured stripe that runs along the middle of the back from front to rear.[6] The belly is pale whitish colour, and the male has a grey throat.[6] The edge of the upper lip is brown with white flecks.[4] A broad dark band runs either side of the nose and continues behind the eye before merging with the patterns along the side body.[4]
As per its namesake, the rough frog's skin has a rough, warty or ridged texture.[7] The throat of the male is finely granular, but the female's throat is smooth.[4] The rough skin distinguishes it from all other frogs that live within its geographical area.[9]
Toes are one-third webbed.[4] The inner metatarsal tubercle is shovel-shaped to assist in burrowing.[4]
The rough frog can be found near seasonal ponds, creeks and claypans in open grassland and closed or open woodland on clay soils.[1][4][5][9] It is distributed across Northern NSW into south-eastern Queensland, but not along the coast or in the ranges.[4] It spends dry periods underground in dormancy and emerges following heavy rain. Roadside reserves are considered as significant habitat areas.[1]
Little is known regarding the behaviour of the rough frog. It is a burrowing frog that will burrow during dry periods, and emerge to breed and feed after extended periods of rain.[6]
Little is known about the rough frog's lifespan. It breeds in flooded depressions during spring to summer, and sometimes in autumn, after heavy rains.[6][1][4] Males sound mating calls that resemble a long moaning growl.[9] Very little data exists regarding reproduction of the Rough Frog, however it is conserved to be similar to Litoria cultripes, in which eggs are laid in large clumps under the surface of water in temporary ponds, swamps or roadside ditches.[6] Larvae are free swimming, tadpoles can grow as long as 7.5 cm being a dull gold/white in colour.[6][1] It is unknown how long they take to develop into frog, but they develop rapidly during warm months before water drys up.[6][10]
The rough frog is defined as Least Concern on IUCN's Red List.[1] The population is stable. There are conservation sites throughout the habitat range of the frog, and it currently occurs in at least one protected area. Fragmentation of population is limited, but there is a continuing decline is area and quality of habitat.[1]
Agriculture and aquaculture including annual and perennial non-timber crops are identified as threats to the rough frog. Future development in south-eastern Queensland may also pose a threat.[1] Direct human impact, urbanisation, tourism and inappropriate catchment management, including the degradation of water quality are also threats to the persistence of this species.[10]

Litoria verrucosa (Ranoidea verrucosa), también conocida como rana verrugosa, es una especie de anfibio anuro del género Litoria, es una rana excavadora originaria de Nueva Gales del Sur y Queensland, Australia.
Esta gran rana es rechoncha y con ojos grandes; alcanza una longitud de 4,9 centímetros. Tiene brazos pequeños y rechonchos y piernas largas y poderosas. La superficie dorsal de la rana verrugosa puede ser de un marrón grisáceo a un verde brillante. Hay pequeñas manchas oscuras en la espalda. La piel es áspera, de ahí el nombre de "rana verrugosa".[1] Una banda oscura va desde el hocico, pasa a través del ojo y el tímpano, y llega hasta el hombro. Una línea pálida corre por el centro de la espalda. La superficie ventral es blanca y granular.
Las patas delanteras de la rana áspera están sin membrana pero las patas traseras sí poseen membranas en la base. El tímpano es visible y carece de almohadillas para los dedos.
La rana verrugosa es una rana excavadora que durante los períodos secos excava, emerge después de períodos prolongados de lluvia para reproducirse y alimentarse. Los machos croen desde fuentes de agua temporales, incluidos arroyos y estanques; su croar es un gruñido largo y gemido. Los huevos se ponen en grandes grupos. Los renacuajos se desarrollan rápidamente en los meses más cálidos para evitar la muerte por el secado del agua.

Dryopsophus verrucosus est une espèce d'amphibiens de la famille des Pelodryadidae[1].
Cette espèce est endémique d'Australie[1]. Elle se rencontre à l'intérieur des terres du Sud-Est du Queensland et dans le centre de la Nouvelle-Galles du Sud, à l'Ouest de la cordillère australienne[1]. La zone de répartition de cette espèce est d'environ 391 700 km2[2].
L'holotype de Dryopsophus verrucosus[3], une femelle gravide, mesure 43,8 mm. Les paratypes mesurent quant à eux de 37,3 à 45 mm pour les mâles et de 37,2 à 49,2 mm pour les femelles. Cette espèce a la face dorsale vert olive très pâle, de petites taches sombres au niveau des verrucosités et des zones intermédiaires gris foncé. Sa dos présente également une ligne vertébrale blanche extrêmement fine. Sa tête est ornée d'une fine ligne sombre s'étendant de la pointe du museau jusqu'à l’œil puis s'élargissant en une grande tache recouvrant le tympan. La face interne de ses cuisses est brun foncé taché de pâle. Sa face ventrale est crème terne avec des mouchetures éparses peu distinctes brun clair sous la mâchoire.
Son nom d'espèce, du latin verrucōsa, « qui porte des verrues », lui a été donné en référence à l'aspect de sa peau[3].
