Bioacoustics of Buenoa deplanatylus

Head. Greatest width of head about 7.8 times anterior width of vertex and distinctly narrower than greatest width of pronotum; head length on longitudinal median line about seven-tenths of length of pronotum. Synthlipsis narrow, three-eighths of vertex width. Frons wide with divergent margins. Tylus conspicuously flat and pubescent. Rostral prong shorter than third rostral segment, with base originating laterally on proximal region of this segment and apex rounded ( Fig. 7 ). Thorax. Pronotum not impressed with posterior margin straight; longitudinal median length about four-tenths of its greatest width. Scutellum larger than longer; longer than median length of pronotum. Fore legs robust. External margin of fore femur straight near the base, without stridulatory area at inner surface; narrowed at apex, its length more than three times its width. Fore tibia with 22 stridulatory teeth, thicker at base; apex of internal margin bluntly projected ( Fig. 8 ). Mid-tibia enlarged at median region of external margin ( Fig. 10 ). Hind femur sinuous with 22 spines on inner surface; external margin with two spines apart along length and three spines near apex; internal margin without a line of crests, with 20 setae ( Fig. 11 ). Abdomen. Hook of left clasper short with apex rounded. Right clasper reniform, with apex straight ( Fig. 12 ). Paratypes (macropterous male and female). Measurements (male/female). Body length: 5.04–5.40/ 5.50; vertex: 0.16/ 0.15; synthlipsis: 0.05–0.06/ 0.06; head length: 0.41–0.47/ 0.43; head width: 1.23/ 1.26; pronotum length: 0.56–0.60/ 0.62; pronotum width: 1.41–1.45/ 1.44; scutellum length: 0.85–1.00/ 1.05; scutellum width: 1.17–1.25/ 1.22; length of fore femur: 0.65–0.71; width of fore femur: 0.21–0.23. Color and structural characteristics similar to holotype . Male paratypes with greatest width of head about 7.6 times anterior width of vertex. Hind femur with 18 to 24 spines on inner surface and 20 to 23 setae on internal margin. Female paratype with greatest width of head 8.4 times vertex width; tylus not flat, slightly rounded. Lateral expansion at mid-tibia not so conspicuous. Hind femur slightly sinuous, with same male distribution pattern of spines on external margin, with 20 spines on inner surface and 22 setae on internal margin.
