The breeding behavior of Glyphoglossus molossus is described from still and video images taken in Cambodia. These
large, burrowing frogs follow the general theme of microhylids that deposit aquatic eggs: explosive breeding in ephemeral water and performing multiple amplectic dips to oviposit surface films of pigmented eggs. A portion of a clutch is released with each dip, a dip lasts for about 6 s, 200-300 eggs are released per dip, and about 5 s pass between dips. The ova have a dark black animal pole and yellow vegetal pole. Expanded datasets on the morphology of the tadpoles of Glyphoglossus from Vietnam and Calluella from Myanmar are presented.
