Lycastrirhyncha nitens is a hoverfly species (Diptera: Syrphidae) first described by Bigot in 1859. It is known from floral visitation studies on Pontederia sagittata (arrowhead water hyacinth), where it exhibits temporal variation in foraging behavior correlated with nectar availability. The species has been documented in wetland habitats across Brazil, with GBIF records indicating presence in all 26 Brazilian states and the Federal District.
