Buenoa communis Truxal, 1953: 1442 [Type locality: vicinity of João Pessoa³, River Juruá, Brazil; Distribution and records: Brazil, Bolivia; Type in Francis Huntington Snow Entomological Collections, University of Kansas (U.S. A)]; Nieser (1968): 122 [Record: Suriname]; Nieser (1975): 184 [Record: Suriname]; Heckman (2011): 478 [Key to Buenoa of South America]; Moreira et al. (2011): 53 [Check-list of Brazil].

Comments. Buenoa communis was not observed in this study, although Truxal (1953) recorded this species in Pará and Amazonas³ States. According to Truxal (1953), B. communis superficially resembles B. platycnemis and B. mutabilis Truxal, 1953, differing from the first species because of the synthlipsis and notocephalon being distinctly narrower; the rostral prong shorter (Fig. 5), the fore femur narrower apically (Fig. 6), and more ridges at the stridulatory area of the fore femur (26 to 31 ridges; on the other hand, B. platycnemis has 11 to 14 ridges) (Fig. 6). Buenoa mutabilis has no records in the Amazon Region, and B. communis differs from this species by the synthlipsis being narrower, the pronotum distinctly tricarinate, more sclerotized ridges in the femoral stridulatory area ( B. mutabilis has 10 to 18 ridges), and the rostral prong originating laterally near the proximal end of this segment. The rostral prong of B. mutabilis, originates laterally and is produced at its apical third.
