Abstract


Two new species of Thraulodes Ulmer, 1920 are described from Rio de Janeiro and São Paulo, Southeastern Brazil, based on male and female imagos. Thraulodes luisae sp. nov. differs from all other species of the genus by the short and wide penes spines, turning up to apex; triangular shape of styliger plate with median projection abrupt and short with rounded apex; abdominal and legs color pattern; and presence of 2–3 weakly marked cross veins basal to bullae. Thraulodes pinga sp. nov. differs from all other species of the genus by the wide shape of styliger plate with median projection short with wide base and truncated apex; abdominal and legs color pattern; and presence of 1 weakly marked cross vein basal to bullae. 


Keywords
