Abstract

A study on the acoustic manifestations of the species Purpuraria erna Enderlein, 1929 and Acrostira euphorbiae García-Becerra & Oromí, 1992 as representatives of the two Canarian endemic genera of Pamphagidae is presented. In these species only females are able to emit songs. Recording of sound emissions in P. erna and A. euphorbiae has allowed measuring different parameters in the domains of time and of frequencies, and the particular song of each species has been characterized. Unlike other Pamphagidae, the environmental temperature is not correlated with the number of songs emitted by the specimens. Significant differences have been found in the songs of the studied species concerning to the domains of frequencies and of time. Before analyzing the rest of Canarian Pamphagidae, the bioacoustic features found for these two species show significative differences between both genera, as genetic and morphological studies have also shown.
