“…These characteristics easily distinguish them from B. ahenea. All larvae of the B. pseudopseudis species group are lotic, benthic, and their LTRF is typically 2(1,2)-3(3)/4(1)-5( 1)-6(1)-7(1)-8(1) (Cardoso, 1983;Sazima and Bokermann, 1977;Eterovick and Brandão, 2001;Lugli and Haddad, 2006a, b;Magalhães et al, 2015), which is distinct from the 2(2)/3(1) labial teeth row formula of B. ahenea. The submarginal papillae of B. pseudopseudis species group are arranged either in 1-4 rows antero-laterally or only one row around the whole oral disc (Sazima and Bokermann, 1977;Eterovick and Brandão, 2001;Lugli and Haddad, 2006a, b;Magalhães et al, 2015), while those of B. ahenea are scattered and may or may not form a row.…”
