Bioacoustics of Buenoa konta

Comments. This species is similar to the brachypterous form of B. salutis because of its reduced length, rostral prong with similar length of the third rostral segment, originating on the proximal region of this segment ( Fig. 30 , 69 ), and the stridulatory area of the fore femur being absent ( Fig. 31 , 70 ). These species are differentiated by the characteristics that make B. konta a species apart from the salutis - group: the vertex strongly prominent before the eyes and synthilipsis not conspicuously narrow (about one-fourth of anterior width of vertex). Besides this, B. konta the tylus is not inflated, but rounded; the apex of the rostral prong is rounded, and subequal to the third rostral segment ( Fig. 30 ); a dark stain accompanying the costal margin of the hemelytra delimits the start of the membrane; the fore femur has a broad apex; the apical teeth of the stridulatory comb of the fore tibia is larger than the basal one ( Fig. 31 ); the left paramere has a hook more robust and the right paramere is narrower than in the second species ( Fig. 32 ). Buenoa salutis has synthlipsis with about one-tenth of vertex width; tylus flat; the apex of the rostral prong sinuous, with equal or greater length than the third rostral segment ( Fig. 69 ); the dark stain at the costal margin of the hemelytra absent; the fore femur has a narrow apex; the stridulatory teeth of the fore tibia is of similar size ( Fig. 70 ); the left paramere has a longer and narrower hook and the right paramere is broader than in B. konta ( Fig. 71 ).
