Anisops femoralis Fieber, 1851: 59 [Type locality: Puerto Rico; Type in Berlin Museum ( Deutschland)].

Buenoa femoralis: Kirkaldy (1904) : 120 [New combination; Note: Puerto Rico]; Kirkaldy and Torre-Bueno (1909): 200 [Note: Puerto Rico]; Jaczewski (1928): 123 [Survey: Paraná ( Brazil)]; Barber (1939): 420 [Survey: Puerto Rico, Virgin Islands]; Truxal (1953): 1382 [Revision; Distribution and records: Peru]; Heckman (2011): 475 [Key to Buenoa of South America]; Moreira et al. (2011): 53 [Check-list of Brazil].

Comments. According to the description by Truxal (1953), the body size of B. femoralis is about 8.32 to 8.64 mm, the head width is seven times the anterior width of the vertex, and the synthilipsis is about one-half of the anterior width of the vertex. The specimen observed here is 7.8 mm in body length; the relation between the head and the vertex is 6.3 times; and the synthlipsis is narrow, a little wider than one-third of the vertex width. Despite the variations observed, the shape of the rostral prong, the chaetotaxia of the fore femur, the number of stridulatory ridges on the fore femur and of stridulatory teeth on the fore tibia, all fit with the description.

These differences can be populational variations, because the described specimens in Truxal’s revision are from Peru. In the original description, Fieber (1851) described specimens from Puerto Rico with “4 Linien8” of length; Barber (1939), from Puerto Rico and Virgin Islands, with 8.00 to 8.50 mm. Relations between the lengths are similar to those described by Truxal. On the other hand, material observed by Jaczewski (1928), from Paraná, has a synthlipsis with width slightly wider than one-third of the anterior length of the vertex and a body length of 7.25 to 7.75 mm, similar to that observed in the specimen from Manaus.

Material. BRAZIL: Estado do Amazonas, Município de Manaus, RFAD, 27.II.1976 (B. Mascarenhas), det. J. F. Barbosa: 1 m macropterous (INPA).
