Calling song An uninterrupted emission trill. The signal consists of phrases lasting for 0.004 ± 0.0001 ( 0.0041 –0.0047 ) seconds, with an interval between phrases of 0.002 ± 0.0001 ( 0.0023 – 0.0028 ) seconds. Overall, the signal exhibits 139.2 ± 1.78 (136–140) syllables per second, with a peak frequency of 5.602 ± 0.051 ( 5.531 –5.663 ) kHz.
diagnosis · Plazi
Diagnosis: ocelli arranged almost in line, forming a concave arc, a line imagined by the lower border of the lateral ocelli touches the median ocellus; external tympanum oblong, internal tympanum small and oval; ectophallic arc wide and short, basal concavity attenuated, apical convexity attenuated, straight and diagonal apical when in lateral view; rami connected in the basal portion, rectangular, as long as wide, apical end simple; continuous trill with pulse period between 6.91–7.61ms, pulse rate between 130–146p/s at 23°C.
