The new species is externally very similar to L. purpurascens Fowler, 1900, as far as the color pattern of the forewings is concerned. Nevertheless, no other described species has a similar arrangement of genital structures, which clearly differ in the shape of the aedeagus with three processes, two subapical and one basal, the paraphysis, which is globose, and a T-shaped connective.	en	Chávez-Gutiérrez, Victoria, Pinedo-Escatel, Adilson (2025): A new species of the leafhopper genus Ladoffa (Hemiptera: Auchenorrhyncha: Cicadellidae) from rainforests of eastern Mexico.
