Remarks. Breuning (1939) described Bisaltes uniformis ( Fig. 20 ) based on a single female from Brazil (no further details). Breuning (1971) indicated a second specimen (no sex reported), from Brazil (Pernambuco), but probably another female because he did not comment about the metatibiae. Breuning (1940) described Bisaltes obliquatus ( Fig. 19 ) based on a single specimen from Brazil (Rio de Janeiro); the sex of the holotype was not indicated, but it is possible to see in the photograph of the holotype that it is a male. Breuning (1940) compared B. obliquatus with B. bimaculatus Aurivillius, 1904 , and according to Breuning (1971), it could be only a variety of this species.

Breuning (1971) separated B. uniformis , B. obliquatus , and B. bimaculatus in his key as follows (translated): “8. On each side a dark brown longitudinal band running the lateral parts of the metaventrite and the first abdominal segment, B. bimaculatus / Without similar bands,” leading to B. uniformis and B. obliquatus ”; “12. Elytra very obliquely truncate at apex (the marginal apical angle stretched into a long lobe), B. obliquatus / Elytra slightly obliquely truncate at apex (the marginal angle stretched into a short lobe),” leading to B. uniformis . Comparing the elytral apex of the holotype of B. uniformis and B. obliquatus it is possible to see that the information from Breuning (1971) is inaccurate as the outer apical angle is very similar in both holotypes. The apex of the right elytron seems to be damaged in the holotype of B. uniformis , but using the left elytron, it is possible to see that the outer angle is also very similar to that in B. obliquatus . In fact, the only difference is that the apex is more strongly oblique toward the sutural angle in B. obliquatus . However, comparing the elytral apex of two females of B. uniformis (MZSP, Fig. 17–18 ), it is possible to see that this difference in the elytral apex is just specific variation. As the elytral pubescence pattern is very similar in the holotypes of B. uniformis and B. obliquatus , we conclude that the latter is a junior synonym of the former.

In fact, as pointed out by Breuning (1940, 1971), B. obliquatus (= B. uniformis ) is similar to B. bimaculatus , but the absence of two dark maculae on abdominal ventrite I, as well as a different elytral pubescent pattern, allow separating these two species.
