Discussion. Differential diagnosis. Related to L. viduus Breddin ( Figs. 18–20 View FIGURES 10–18 View FIGURES 19–27 , 61, 67–68 View FIGURES 60–67 View FIGURES 68–75 ) by having the femora bicolorous, shiny brown to black with posterior third yellowish orange except the apex shiny brown to black; anterolateral and posterolateral margins of pronotal disk yellow; connexival margins III–VII yellow; dorsal abdominal segments III–VII black and pleural abdominal margins III–VII yellow. In L. viduus described from Ecuador, the acetabulae are black, the pronotal disk lacks a yellowish longitudinal stripe at midline, and the postocular area is yellow and the callar region yellow to brown. In L. aburtonia sp. nov., ( Figs. 18 View FIGURES 10–18 , 61 View FIGURES 60–67 ), described from Brazil the acetabulae has a yellowish orange discoidal spot, the midline of pronotal disk has an irregular yellowish orange longitudinal stripe running from inner border of calli until the posterior border, and the postocular area is black and callar region brown.
