Tylopsis brevis Ragge, 1964


Tylopsis brevis Ragge, 1964 

[B] CH 4951 ♂, CH 4952 ♀, [C] CH 4975 ♂

Following Ragge’s key (1964) the specimens were identified as T. brevis  with type locality Volcan Nyamlagira in the Kivu region.

Song. The calling song of a male (not captured) was recorded in the field near Tshivanga [C] at night. Most often echemes containing four (rarely less) syllables were heard ( Fig. 12View FIGURE 12), the interval between the first and second a little bit larger than during the others. However, a few long continuous syllable series (up to 12 s) with the same syllable interval of about 200 ms (13.5 ºC) were also recorded. Each syllable consisted of few impulses similar as in Tylopsis lilifolia ( Heller 1988)  .

The stridulatory file contains relatively few teeth (as in Tylopsis lilifolia  ; Heller 1988).
