Leptolalax kecil is a species of megophryid frogs found in the Cameron Highlands of Peninsular Malaysia.[1] It is only known from its type locality, but it is expected to have a wider distribution in the Cameron Highlands. This species may have been erroneously identified as Leptolalax gracilis.[2]
Leptolalax kecil is a small-sized toad, similar in size to L. pluvialis. Males recorded were 19mm21mm in snout-vent length and one female was 25mm. Male Leptolalax kecil call at night on the ground near streams. The call differs from those known in other species of Leptolalax: male emits only one short, clearly pulsed call at a time, in contrast to long, successive notes of other species.[1]
The species has not been assessed by the IUCN, but habitat loss due logging and agriculture is occurring near the type locality.[1]
