Understanding the evolutionary origins of communication signals requires careful study of multiple species within a known phylogenetic framework. Most cricket species produce low-frequency calls for mate attraction, whereas they startle to high-frequency sounds similar to bat echolocation. Male crickets in the tribe Lebinthini produce high-frequency calls, to which females reply with vibrational signals. This novel communication system likely evolved by male sensory exploitation of acoustic startle to high-frequency sounds in females. This behavior was previously described for the Lebinthini from Asia. Here we demonstrate that this novel communication system is found in a Neotropical species, Ponca hebardi, and is therefore likely shared by the whole tribe Lebinthini, dating the origin of this behavior to coincide with the origin of echolocation in bats. Furthermore, we document male duets involving both acoustic and vibratory signals not previously described in crickets, and we tentatively interpret it as competitive masking between males.

的新型通讯系统与蝙蝠的回声定位同时产生，并且包括男女多模态通讯

了解通信信号的进化起源需要在已知的系统发育框架内仔细研究多种物种。大多数物种发出低频声音来吸引伴侣，而它们却对类似于蝙蝠回声定位的高频声音感到吃惊。Lebinthini部落中的雄发出高频声，雌性则发出振动信号。这种新颖的通信系统可能是通过男性对声音惊吓的感官开发向女性的高频声音发展的。先前针对亚洲的Lebinthini曾描述过这种行为。在这里，我们证明了这种新的通讯系统是在新热带物种庞卡黑巴迪中发现的，因此很可能由整个Lebinthini部落共享，此行为的起源与蝙蝠的回声定位起源一致。此外，我们记录了涉及板球的声波和振动信号中未曾描述过的雄性二重唱，我们初步将其解释为雄性之间的竞争性掩蔽。
