Types of signals of males and females of two species of the Enchenopa binotata (Hemiptera: Membracidae) treehoppers complex, which are shown in Fig. 2. The sounds are: (1) the main advertisement male signal without the female mimic signal; (2) the main signal followed by a female mimic signal without pulses; (3) the main signal followed by a female mimic signal with pulses; and (4) a male–female duet of the male signal followed by a female response. Each of the four signal groups are separated by 1.5 s of silence.
