Genomic analysis reveals new species and subspecies of butterflies Author Zhang, Jing Author Cong, Qian Author Shen, Jinhui Author Song, Leina grishin@chop.swmed.edu Author Grishin, Nick V. text The Taxonomic Report of the International Lepidoptera Survey 2023 2023-12-13 11 6 1 63 journal article 2643-4806 4594F1CA-9EE8-4A80-A0CA-792676139D20 Mesosemia nesti Hewitson, 1858 , Mesosemia acuta Hewitson, 1873 , and Mesosemia eurythmia Stichel, 1915 belong to the genus Ectosemia Grishin, 2021 Genomic sequencing of Mesosemia nesti Hewitson, 1858 ( type locality in French Guiana )—the species transferred to Semomesia Westwood, 1851 ( type species Papilio croesus Fabricius, 1777 ) in Callaghan and Lamas (2004) —and Mesosemia acuta Hewitson, 1873 ( type locality in Brazil , possibly Rio de Janeiro ) reveals that they are not monophyletic with Mesosemia Hübner, 1819 ( type species Mesosemia philoclessa Hübner, 1819 ) that includes Semomesia as its junior subjective synonym, but instead originate within the genus Ectosemia Grishin, 2021 ( type species Papilio eumene Cramer, 1776 ) ( Fig. 15 ). Therefore, we propose the following new combinations : Ectosemia nesti (Hewitson, 1858) and ( type locality in Brazil : Amazonas), we tentatively place it in Ectosemia due to wing pattern similarities: Ectosemia eurythmia (Stichel, 1915) , comb. nov .
