( Figs. 37 View FIGURE 37 A–H, 52A–C)

Diagnostic remarks. An easily recognizable katydid, characterized by contrastingly light venation of the tegmina ( Fig. 37H View FIGURE 37 ), white accents on the pronotum and abdominal terga, large spines on the ventral margins of hind femora, and a prominent crest on the metazona of pronotum. The male cerci are simple, weakly incurved and armed with a small apical spine ( Figs. 37D, E View FIGURE 37 ). The stridulatory file has 43–47 teeth ( Fig. 37C View FIGURE 37 ). Females in the population in central Mozambique have the ovipositor nearly 5 times shorter than the hind femur ( Fig. 37G View FIGURE 37 ), albeit there appears to be a significant variation in the length of the ovipositor in this species.

Bioacoustics. The call of T. zebrata is a series of single syllables, produced at the rate of 3 syllables/s; mean syllable duration is 0.0411 s (SD=0.00975, n=39); the peak frequency of the call is 11.1–12.8 kHz ( Figs. 52 View FIGURE 52 A–C). The call is audible from a few meters.

Distribution and natural history. T. zebrata is distributed widely in southern and East Africa, south of latitude 4°S ( Ragge 1980). It is found in Acacia woodland, where it feeds on a number of small-leaved trees of the family Fabaceae . Females lay eggs singly on the surface of tree bark, relatively low to the ground. Similar to females of Arantia , following the deposition of an egg the female covers it with pre-chewed bits of bark.

Measurements (3 males, 7 females). body w/wings: male 46–46.5 (46.2.3), female 45–51.4 (48.82); body w/o wings: male 25–26 (25.3.6), female 26–31 (29.31.8); pronotum: male 4–5.5 (4.8.8), female 5–5.5 (5.2.3); tegmen: male 34–35 (34.5.5), female 34.5–37.5 (36.61.1); hind femur: male 21–23.5 (22.21.3), female 22–23.9 (22.9.6); ovipositor: 5–6 (5.5.4) mm.
