According to Azevedo (1999), R. septemlineatus Kieffer, 1906 and R. lobatifrons Kieffer, 1910 are very similar to each other, and they can be distinguished mainly by the shape of ventral margin of the paramere, which is dilated submedially in R. septemlineatus and medially in R. lobatifrons . Here we analyzed a large series and noticed a wide and intermediary range of variation of this character between both species, so that we considered R. lobatifrons as a junior synonym of R. septemlineatus .

R. septemlineatus was known from Nicaragua, Panama and Brazil (Amazonas, Espírito Santo, São Paulo, Paraná and Santa Catarina). Here, with additional localities of R. lobatifrons , this species is recorded from Trinidad, French Guiana, Ecuador, Brazil (Amapá, Pará, Acre, Rio de Janeiro and Paraná), Peru, Bolivia and Paraguay. In this series, frons and dorsum of thorax inconspicuously coriaceous; frontal angle of ocellar triangle acute or almost right; ventral margin of the paramere dilated medially or submedially; appendicular process with base width 0.7x or 1.0x process width, apex rounded or angulate ( Fig. 32–34 ); aedeagus with median portion abruptly or progressively narrow.
