New record. BRAZIL • 1 ♂; São Paulo, Vale do Ribeira, Sete Barras , station 3; 24°17′31″0S, 048°06′29″W; 7 Feb. 2013; G. Bertini et al. leg.; CEIOC 74827 .

Identification. Rhagovelia plaumanni belongs to the robusta group of species, in which the pronotum of the apterous form completely covers the mesonotum, the distal spur of the hind tibia is straight or slightly curved, never crescent-shaped, and the posterolateral margins of male abdominal segment VII lack robust black denticles ( Polhemus 1997; Moreira et al. 2012). The male above was identified based on the key provided by Magalhães et al. (2016). This specimen bears proepisternum without black denticles, hind femur lacking a long, sharp spine removed dorsally from the two rows of spines along the posterior margin, hind tibia with several subequal spines, in addition to the apical spur, abdominal mediotergite VII shining black, and sides of abdominal segment VII without patches of black denticles.

Known distribution. Brazil, Paraguay ( Polhemus 1997). Distribution in Brazil. Paraná ( Polhemus 1997), Rio Grande do Sul ( Polhemus 1997), Santa Catarina ( Polhemus 1997), São Paulo ( Polhemus 1997; this work).
