Call descriptions may facilitate studies on behavioural ecology and support taxonomists in their efforts to delimit species. The Indochinese Brown Bullfrog (Kaloula indochinensis) was described in 2013 and occurs in evergreen forest in Indochina. Whilst the tadpole of the species was recently described, little else is known about the biology and ec...
