Neobatrachus is a genus of burrowing ground frogs native to Australia. They occur in every state except Tasmania, however this genus is absent from the far north of Australia and most of Queensland. Most of the species in this genus occur in south-western Western Australia. They are often found in arid areas and burrow underground to avoid dehydration. They are typically found in temporary claypan and flooded grassland habitats.
These burrowing frogs have special genetic characteristics that help them to live in extreme environments. They stand out because some species are tetraploids instead of diploids.[1]
All species have a similar body shape, they are rounded and squat with large eyes and the pupils constrict vertically. The limbs are short and the hands are free from webbing while the feet are partially webbed. Males lack a vocal sac. Approximately 1000 eggs are laid in a chain in still water.
The reproductive cycle is dependent on sufficient rainfall, an unpredictable event in the arid and semiarid regions of Australia. When a period of rain creates pools of water they emerge from their burrow to meet in large numbers. The breeding activity becomes frantic as the males seek out an opportunity, several individuals may sometimes be seen clambering over each other on a single female. Neobatrachus tadpoles may feed on the weaker individuals in a pool as available food is exhausted or water evaporates.[2]
The genus was first described by Wilhelm Peters in 1863.[3] A taxonomic revision of the genus was published in 2010, providing clarification to the names of several species and investigating the identity of the specimen examined for the author's earlier description of Neobatrachus albipes.[4]
A genus name, Neoruinosus Wells and Wellington, 1985, erected to separate Neobatrachus sudelli as a monophyletic species or species group was placed in synonymy in the 2010 revision.[5]

Neobatrachus aŭ Novbatrakoj estas genro de grundonestumantaj ranoj indiĝenaj de Aŭstralio de la familio de Mjobatraĥedoj. Ili loĝas en ĉiuj subŝtatoj escepte en Tasmanio, tamen tiu genro forestas el la plej malproksima nordo de Aŭstralio kaj plej el Kvinslando. Plej el la specioj en tiu genro loĝas en sudokcidenta Okcidenta Aŭstralio. Ili estas ofte troviĝantaj en aridaj areoj kaj nestotruoj subgrunde por eviti senakvigon. Ili troviĝas tipe en portempaj argilecaj kaj inundoherbejaj habitatoj. Ĉiuj specioj havas similan korpoformon, ili estas rondoformaj kaj kaŭras montrante grandajn okulojn kaj la pupilojn kiel vertikalaj fendoj. La kruroj estas mallongaj kaj la manoj estas senmembranaj kvankam la piedoj estas parte membranaj. Maskloj ne havas voĉosakon. Proksimume 1000 ovoj estas demetataj laŭ ĉeno de trankvila akvo.

Neobatrachus é um género de anfíbios anuros, nativos da Austrália. Muitas das espécies deste gênero ocorrem no sudoeste do estado da Austrália Ocidental. Eles são muitas vezes encontrados em terras áridas e em buracos no solo para se proteger da desidratação, mas são encontros em geral em barreiros temporários e habitats encharcados. Todas as espécies possuem aparência similar. São redondos e atarracados, com grandes olhos e pupilas verticais. Os membros são curtos e os machos carecem de sacos vocais.
