Comments. Only the macropterous form of this species is known, and is easily recognized by its body color being predominantly brown and the internal margin of the fore tibia being acutely projected at apex (Fig. 55).
The general appearance of B. truxali resembles B. tibialis because of the color, the approximate body length, and the synthlipsis being narrow, shorter than one-half of the vertex width. Buenoa truxali can be recognized by the internal margin of the fore femur being rounded near the base and with its apex being broad (Fig. 54); the apex of the fore tibia is acute (Fig. 55); and the stridulatory teeth of the fore tibia is wide at extremities and shorter at the median region of the stridulatory comb (Fig. 54). In Buenoa tibialis the internal margin of the fore femur is straight near the base and the apex is comparatively narrow (Fig. 51); the apex of the fore tibia is rounded (e.g. Fig. 9); and the stridulatory teeth are of similar size (Fig. 51). Furthermore, in B. tibialis the mid-tibia are enlarged at the median region of the external margin (e.g. Fig. 10), and the hind femur is sinuous with a line of short spines on its inner surface (e.g. Fig. 11). Both features are absent in B. truxali. The female of both species can be differentiated by the expansion at the mid-tibia and by the shape of the hind femur of B. tibialis.
