The male advertisement call consists of a single, modulated, non-pulsed note lasting about 1.2 seconds. The calls are emitted at a rate of about 8 calls per minute.^[3]

Tadpoles have an ovoid body when viewed dorsally and globular when viewed laterally. The body is dark brown and has two dark stripes that continue onto the tail. Gosner stage 37 tadpoles measure about 27 mm (1.1 in) in total length; the body is about 10 mm (0.4 in).^[3]
