Bioacoustics of Hapithini

Diagnosis: Small to medium-sized, FWs developed, sometimes brachypterous ( Margarettia and Knyella ), bearing a well-developed stridulatory apparatus ( Fig. 14A ). Male metanotum sometimes with median projection; FWs mirror with or without a dividing vein, generally shorter than apical field ( Fig. 14B ); tympana frequently present on both sides of TI; TIII subapical spurs generally 8/6, with variations from five to ten on inner margin and from five to seven on outer margin; apical spurs of tarsomere I of leg III shorter than tarsomere I of leg III. Ovipositor ventral valves laterally serrulate. Male genitalia: LLophi dorsal to MedLophi ( Fig. 14C ; Supporting Information, Fig. S8D ); PsP lateral and connected to pseudepiphallic (Supporting Information, Fig. S8C ); EctF bilobate and connected distally, proximal portion convex (forming dorsal cavity) in dorsal and ventral views (Supporting Information, Fig. S8C ).
