Here a new subgenus of Lepidocyrtus Bourlet from South America is proposed. Fractocyrtus subgen.n. differs from other subgenera by tergal polychaetosis, dental tubercle truncate and dentes with numerous spine-like chaetae. Four new species of Lepidocyrtus are described, two of Setogaster Salmon and two of Fractocyrtus subgen.n. Lepidocyrtus (S.) amazonicus sp.n. and L. (S.) multisensillatus sp.n. are similar to L. nigrosetosus Folsom by basomedian field with chaetae smooth and dental tubercle rounded, but differ in dorsal chaetotaxy. Lepidocyrtus (F.) americanus sp.n. and L. (F.) mateosi sp.n. are similar by presence of numerous dental spines, but differ in chaetotaxy. Due to inconsistencies concerning scales on appendages of Lepidocyrtus subgenera, four synonyms are proposed, and the characteristics diagnostic to subgenera are shape and presence of dental tubercle, dental spines, mucronal spinelet and apical bulb of fourth antennal segment. An identification key to subgenera is also provided.
