Abstract
Leptodelphax maculigera (Stål, 1859 STÅL, C., 1859. Hemiptera: species novasdescripsit. In: O.H.M. KONUNG, ed. Kongliga Svenska Fregatten Eugenies Resa Omkring Jorden. Stockholm: Kungliga Svenska Vetenskaps Akademien, vol. 4, pp. 219-298. ) (Hemiptera: Delphacidae: Delphacinae: Delphacini) is a new combination of Delphax maculigera (Hemiptera: Delphacidae: Delphacinae: Delphacini), described by Stål, in 1859, from Mauritius (Stål, 1859 STÅL, C., 1859. Hemiptera: species novasdescripsit. In: O.H.M. KONUNG, ed. Kongliga Svenska Fregatten Eugenies Resa Omkring Jorden. Stockholm: Kungliga Svenska Vetenskaps Akademien, vol. 4, pp. 219-298. ). Other records of this species and specimens of Delphacidae were mainly taken in other islands of the Western Indian Ocean, recognizing the African derivation of delphacid fauna (Fennah, 1964 FENNAH, R.G., 1964. Delphacidae from Madagascar and the Mascarene Islands (Homoptera: fulgoroidea). Transactions of the Royal Entomological Society of London, vol. 116, no. 7, pp. 131-150. http://dx.doi.org/10.1111/j.1365-2311.1964.tb01084.x. http://dx.doi.org/10.1111/j.1365-2311.19... ). The genus Leptodelphax is represented in several countries of Africa, Egypt, Cyprus, Turkey, and Israel (Nast, 1958 NAST, J., 1958. Homopterological Notes XII.

Leptodelphax maculigera was recently recorded in Central-West of Brazil, representing the first report of this species in the American continent (Ferreira et al., 2023 FERREIRA, K.R., BARTLETT, C.R., ASCHE, M., SILVA, L.R.S., MAGALHÃES, V.S. and GONDINHO, K.C.A., 2023.
