417C8787FFA8FF8FFF186A7EFB8AFF72.taxon	description	Sequence Data and Analysis. For the novel taxa, sequence data was successfully obtained for all selected markers. Products the size of 315, 529, 633, 1,365, 741 and 795 base pairs (bp) were recovered for the markers H 3, COI 5 ’, COI 3 ’, 18 S, 28 S D 8 region and 28 S D 9 – D 10 region, respectively. All sequences generated for the novel taxa were deposited in GenBank and corresponding accession numbers are presented in Supplementary Table 1. The phylogeny constructed from concatenated data of all loci showed very strong statistical support (99.6 / 100) for the monophyly of Geminimyndus gen. nov. and very strong support (100 / 100) for it resolving adjacent to Eumyndus (Fig. 18).	en	Bahder, Brian W., Stroiński, Adam, Labbe, Frederic, Bartlett, Charles R., Ratsimbazafy, Miangaly Raharimandimby, Randretsiferana, Safidinirina Armande, Razafindrakotomamonjy, Andrianatenaina, Hasinjaka, Rasolondalao Harin’Hala, Pilet, Fabian (2026): New planthoppers (Hemiptera: Cixiidae) from Madagascar support the establishment of a new genus, the revised status of Eumyndus perinetensis, and an updated molecular phylogeny of Malagasy Oecleini.

417C8787FFA8FF8FFF186A7EFB8AFF72.taxon	discussion	Remarks. Geminimyndus gen. nov. superficially resembles Eumyndus. Historically, Eumyndus was separated from Myndus by the former lacking a median carina on the frons, whereas Myndus possessed this carina. The presence of this carina in G. perinetensis comb. nov. cast doubt on the validity of this character for defining Eumyndus. However, with the proposed status change for G. perinetensis comb. nov., the presence of a median carina is (thus far) a consistent feature for Geminimyndus gen. nov., and with its removal from Eumyndus, the lack of the carina on the frons is now consistent for Eumyndus. Additionally, all three species of Geminimyndus gen. nov. possess a large acrometope, whereas this is lacking in Eumyndus. Furthermore, the presence of paired processes arising from the phallobase in Geminimyndus gen. nov. is a strong character in contrast to the single process observed in Eumyndus to support the establishment of the genus. Thus far, three species have been observed with paired processes and two species of Eumyndus, both possessing a single process, have been observed, supporting the consistency of this character. This distinction is also strongly supported by molecular data for a variety of molecular markers. While specimens of Myndus for molecular study are lacking, the general structure of the genitalia would suggest it is more closely related to Haplaxius than to either Eumyndus or Geminimyndus gen. nov.	en	Bahder, Brian W., Stroiński, Adam, Labbe, Frederic, Bartlett, Charles R., Ratsimbazafy, Miangaly Raharimandimby, Randretsiferana, Safidinirina Armande, Razafindrakotomamonjy, Andrianatenaina, Hasinjaka, Rasolondalao Harin’Hala, Pilet, Fabian (2026): New planthoppers (Hemiptera: Cixiidae) from Madagascar support the establishment of a new genus, the revised status of Eumyndus perinetensis, and an updated molecular phylogeny of Malagasy Oecleini.
