Buenoa tarsalis Truxal, 1953: 1392 [Type locality: Rio Sao Paulo Road, State of Rio de Janeiro, Brazil; Type in Francis Huntington Snow Entomological Collections, University of Kansas ( U.S.A.)]; Nieser (1970): 87 [Survey: South America; Record: Brazil]; Nieser (1975): 194 [Note: borders of Guyana Region]; Nieser and Melo (1997): 15 [Key to Buenoa of Minas Gerais, Brazil]; Melo and Nieser (2004): 45 [Faunistical notes; survey: Januária ( Brazil)]; Barbosa et al. (2010b): 561 [Key to Buenoa of Rio de Janeiro, Brazil]; Ribeiro et al. (2010): 308 [Survey: Rio de Janeiro ( Brazil)]; Heckman (2011): 475 [Key to Buenoa of South America]; Moreira et al. (2011): 55 [Check-list of Brazil].

Comments. Buenoa tarsalis is easily recognized by its great length, around 7.0 mm, and by the first tarsal segment of the mid-leg emarginate.

Because of the length and the pale color, B. unguis resembles B. tarsalis . These species can be differentiated by the fore tarsus being swollen with its claws hooked ( Fig. 58 ), and the first mid-tarsomere not being emarginated in B. unguis; the fore tarsus and claws of B. tarsalis are not modified and the first mid-tarsomere is emarginated ( Fig. 48 ).
