( Figs. 5J , 22 A–E, 50A–C) Diagnostic remarks. One of the largest katydids in Mozambique , this slender insect can be identified by its elongate body, narrowly conical and hypognathous head, slender and spiny legs, and a distinct white line running along the sides of the body ( Figs. 22A, D ). Its coloration varies from light green to brown. From its relative Clonia wahlbergi Stål, 1855 it can be distinguished by the shortened, black and yellow-bordered hind wings ( Fig. 22E ), and the shape of the head ( Fig. 22C ) and cerci ( Fig. 22B ). Bioacoustics. Males call at night from tall clumps of grass, producing a long, uninterrupted train of short syllables at the rate of 15–23 syllables/s (at 26°C), each syllable contains a short impulse created by the tegmina opening and a longer group of impulses produced by the tegmina closing; mean syllable duration is 0.05147 (SD=0.08954, n=89); the peak frequency of the call is 14.6–16.9 kHz ( Figs. 50 A–C). The call is audible to the human ear from a few meters as a very soft buzz.
