Buenoa macrotrichia Truxal, 1953: 1429 [Type locality: Vicinity of San Pedro, Peru; Type in Francis Huntington Snow Entomological Collections, University of Kansas ( U.S.A.)]; Heckman (2011): 471 [Key to Buenoa of South America].

Comments. According to Truxal (1953), this species has several large setae on the inner posterior margin of the fore femur. These setae are larger than others with a crown apex, and have been observed in other species and are not, therefore, unique to B. macrotrichia .

This species is very similar to B. platycnemis because of the synthlipsis slightly shorter than one-half of vertex width; the longer rostral prong, distinctly longer than the third rostral segment; and the tylus inflated. Buenoa macrotrichia , indeed, has a rostral prong with a distinct shape ( Fig. 33 ), the pronotum is not tricarinate, and there are fewer teeth in the stridulatory comb of the fore tibia ( Fig. 34 ).
