“…There are fourteen different types of stridulatory devices in Heteroptera (Leston 1957). Some of them are known to occur in several families, and others are restricted to a few genera or a single species (Goula 2008). The most widely distributed type is the forewing edge stridulitrum -hind femur plectrum, which is present in some members of Dipsocoromorpha, Leptopodomorpha, Cimicomorpha, and several Pentatomomorpha (Schuh and Slater 1995).…”

“…Stridulatory devices are sound-producing structures composed of a movable part (plectrum) that rubs against a stationary portion (stridulitrum), producing an acoustic signaling (Goula 2008). In Heteroptera, these structures frequently occur in both sexes, but in some cases may be found only in females or males, and there may also be sexual dimorphism (Leston 1957).…”

The presence of the stridulatory structures has been empirically used as a diagnostic character for Pachycorinae, but it is also present in Hoteinae and two genera of Odontotarsinae. The stridulitrum is present mostly on sternites V-VI in Scutelleridae, associated with a plectrum on the hind tibiae. These structures have been recently analyzed under scanning electron microscopy (SEM), however only nine of the twenty-seven Pachycorinae genera were examined, moreover, the tibial plectra were not examined. In this work, we investigated the stridulatory device of 26 genera of Pachycorinae. The morphology of these structures was examined and described under light stereomicroscope and SEM. We report two patterns of stridulitrum: (1) smooth carinae, found in 24 genera; (2) coarse carinae, composed of many small teeth similar in size, found in three genera. Two main patterns were found regarding the tibial plectra: (1) rounded tubercles that were conspicuous in three genera and inconspicuous in 23 genera; (2) flat tubercles found in two genera. Our results demonstrate that the stridulatory devices have taxonomic significance within Pachycorinae and should be considered in further studies.
