Chiasmocleis bassleri

Syncope bassleri (common name: Bassler's humming frog) is a species of frog in the family Microhylidae.It is found in the Amazon biome of Brazil, Colombia, Ecuador, and Peru, and possibly in Bolivia. Syncope bassleri are relatively small frogs: males measure about 15–20 mm (0.59–0.79 in) and females about 21–26 mm (0.83–1.02 in) in snout–vent length. Male frogs can be heard calling from under wet leaf litter, near pond edges. The call consists of many sporadically emitted, short multi-pulsed notes (3–6 pulses). Syncope bassleri is an abundant and widespread species in suitable habitats. It is found in terra firma primary and secondary tropical rainforest and in seasonally flooded forest. They usually occur near isolated pools, hiding under leaves or pieces of bark. Syncope bassleri is adversely impacted by habitat loss due to forest clearing.
