In this study, which was conducted with captive specimens kept in wooden cages and separated by sex, the sounds produced by Jacobsiella imitans (Brunner, 1882) and Leptopternis candidus lusitanicus (Ebner, 1941) (Orthoptera, Acrididae) are described. Sounds were recorded with a digital audio tape recorder; the signal was digitized and then analysed with the Avisoft\® software. Two types of sound, both produced by stridulation, were recorded in these species: an interaction song, produced when specimens are disturbed by others, and a courtship song, emitted by males when mounting another individual in trying to copulate. In both species, females are mute. Data concerning the time and frequency domains of these sounds are presented. The behaviour observed by both species in nature and that displayed when interacting with other individuals and during courtship are described. The role of song as an isolation mechanism is discussed.

The family Pamphagidae, within Orthoptera, is very diverse with regards to its sound production mechanisms. Its genus Acinipe, a Mediterranean element, is composed of several species with a quite restricted distribution, but there is limited knowledge on their sound production. Acinipe segurensis (Bol\ívar, 1908) is an endemic species from the Mediterranean area of the Iberian Peninsula, and there is no information on its sound production. The sounds produced by this species have been recorded and studied at the time and frequency domains, allowing their description for the first time. The sound is composed of echemes of single or double syllables, emitted by females when isolated from males. Both tegmina and wings are involved in the sound production through a ridge located at the basal third of the tegminal inner face and the costal vein of the wing. The sound and sound production mechanism are discussed in relation to data available from other Pamphagidae species. The results of the present study illustrate the interest in studying sound production in this family, which has secondarily adapted some structures for its function, causing diversity in both sounds and sound production mechanisms.
