The genus Mannophryne includes 19 described species from Venezuela and two species from Trinidad and Tobago. We described for the first time the advertisement call of Mannophryne lamarcai, an endemic and Critically Endangered species from the Cerro Socopó at western Venezuela. M. lamarcai was spatially restricted in appropriate habitats. Males were calling actively on top of rocks and fallen trucks, along small streams. Calling activity was registered between 13:00 - 19:00 h. The call of M. lamarcai comprises a single note arranged in call groups of 37 to 202 notes (130.35; ± 45.62) with five harmonics. The second harmonic is the dominant with a frequency band of 3.7 kHz. The call lasts the duration of one note from 0.01 to 0.03 s (0.033 ± 0.006), while the call group lasts up to 16 s (5.88 – 28.34; ± 5.51. Call bouts were arranged in groups of eight trains (6 – 13; ± 1.73), with an inter-note gap of 0.08 s (0.05 to 0.33; ± 0.04). The inter-note interval was longer during the first 4.5 s of the call group than later.
