Character State Reconstruction of Call Diversity in the Neoconocephalus Katydids Reveals High Levels of Convergence

We describe each species’ calls for the three call traits ‘call structure’, ‘pulse pattern’, and ‘pulse rate.’ The character states for these three call traits are listed in Table 1.

Table 1: Description of Neoconocephalus calls

The character states for the three call traits of the 17 species considered. C continuous, D discontinuous (=versed) call structure; Pulse rates < 100 Hz are classified as ‘slow’, > 100Hz as fast. The call structure in N. ensiger was equivocal, indicated by a ? (see text); * the verse duration for N. ensiger as given here interprets individual pulses as chirps (see text).
