Specimen studied. Holotype female. MEXICO . Chiapas. 20 km W Tuxtla Gutiérrez, 1020 m. 30.iv.1993. Beating branches of tree in pasture land. A. N. García Aldrete (CNIN).

Etymology. This species honors the memory of W. L. Distant, author of the Insecta. Rhynchota. Hemiptera- Heteroptera. Volume I (1880–1893), and co-author of the Insecta. Rhynchota. Hemiptera-Homoptera. Volume I (1881–1905), of the Biologia Centrali-Americana.

Remarks. L. albertina García Aldrete (1992), L. buenoi García Aldrete (2017), L. contrerasi García Aldrete (2015 b), and L. michiliensis García Aldrete (1991) have micropterous or brachypterous females; L. distanti n. sp., differs from all of them in the shape of the subgenital plate, and in the shape of the gonapophyses and ninth sternum.
