Bioacoustics.— Morris and Beier (1982) describe the call of S. femorata (a population from Monteverde) as a steady sequence of paired lisps, with the lisps repeated every 10 seconds at 16°C. Each lisp consists of a faint minor pulse train followed by a much longer and more intense major pulse train (the minor pulse train could not be detected in the recordings made by M. Greenfield in Monteverde, see Fig. 57 G). Both lisps in a pair have the same structure. Most of the energy of the call is allocated near 11 kHz, and in a broader higher frequency peak centered on 27 kHz.

Diagnostic description.— General characteristics as described above. Tegmina shortened, reaching 6th or 7th abdominal tergite, approximately oval in shape ( Fig. 26 A); hind wings greatly reduced about as long as 1/3 of tegmina. Stridulatory file of male 1.3 mm long, with 202 lamelliform teeth, maximum width of file 130 μm ( Fig. 48 A); teeth of file uniform in thickness, evenly spaced and smoothly narrowing towards proximal end. Mirror of stridulatory apparatus approximately square, with distal margin of mirror convex. Male cercus with dorsal lobe pointed apically and of the same color or only slightly darker than remainder of cercus ( Figs. 25 D-E). Measurements .— Table 17 .
behaviour · bio.acousti.ca
The song is a steady sequence of paired lisps (Fig. 13). At 16 C 16 lisp pairs are repeated in 10 s. The oscilloscope resolves each lisp into a very faint minor pulse train followed by a much longer in tense major pulse train. This PTG remains the same for both lisps of the pair. The complex-wave pulses of the trains tend to run together toward the concluding half of the major pulse train. The spectrum (Fig. 2) has a very tall sharp peak near 11 kHz and a broader higher frequency peak centred on 27 kHz. It is possible to confuse the song of S. femorata with the two-lisp call of L. hebardi, but S. femorata appears to have a higher song rate for any temperature and there are quality differences e.g. a quavering quality to Lophaspis due to the greater number of pulse trains per lisp; the double lisp of S. femorata thus sounds 'crisper'.
