Type material. HOLOTYPE female: VENEZUELA: Territorio Federal, Amazonas, Parque Nacional Duida, Marahuaka , Culebra , 250 m, 30°33´N- 65°55´W, 9–13–iii–1985, Exp. Marahuaka, Fund. Terramar ( UCVM). GoogleMaps

Etymology. From the Latin “ lentus ” meaning flexible, slow, viscous.

Discussion. Differential diagnosis. Like in L. ducalis (Stål) ( Figs. 3 View FIGURES 1–9 , 42 View FIGURES 37–43 ), L. fasciatus (Dallas) ( Figs. 6–7 View FIGURES 1–9 , 48–49 View FIGURES 44–51 ), L. proximus ( Figs. 10 View FIGURES 10–18 , 50 View FIGURES 44–51 ) and the new species here described, L. navus ( Figs. 12 View FIGURES 10–18 , 69 View FIGURES 68–75 ), the corium has a completely yellow to yellowish orange transverse fascia. In L. lentus s p. nov., ( Fig. 13 View FIGURES 10–18 , 53 View FIGURES 52–59 ), the yellow transverse fascia is narrow in zig-zag while on the other species are wider. The hind femora of L. fasciatus are entirely yellow, while on L. ducalis , L. proximus and L. navus the dorsal surface is black with bluish green reflections and ventrally yellow to yellowish orange, and in L. lentus entirely black. In L. fasciatus , L. proximus , and L. navus , the propleuron is entirely yellow to yellowish orange, while on L. ducalis and L. lentus yellow to yellowish orange with wide quadrate or elongate black spot. In L. ducalis the scutellum is yellow with a broad black basal spot at each side of midline, the pronotal disk has a slender yellowish longitudinal stripe across midline, and fore and middle femora are dorsally black and ventrally mostly yellow. In L. lentus the scutellum including the apex are black with bluish green reflections, the pronotal disk without yellow longitudinal stripe across midline, and fore and middle femora entirely black.
