Ectosemia Grishin, new genus

http://zoobank.org/ 8AB8B269-CAE8-417D-BF0D-E46043B20CBE

Type species. Papilio eumene Cramer, 1776 .

Definition. Species in this clade are currently in Mesosemia Hübner, [1819] (type species Mesosemia phicoclessa Hübner, [1819] , which is Papilio philocles Linnaeus, 1758 ), but are quite distant from it falling much outside of the Mesosemia radiation and originating during the earlier round of radiation (Fig. 16). Therefore this clade is a taxon of the same rank, a genus. This new genus differs from Mesosemia by the following combination of characters: hindwing not lobed in the middle, each wing with 2 broad and straight parallel bands: discal and postdiscal, bands do not encircle forewing eyespot as in most Mesosemia , but discal forewing band bends distad at costa, no striations, discal cell eyespots developed ventrally on both wings, elongated along the cell, with 3 white spots inside (sometimes 2 on hindwing). Furthermore, the following combination of nuclear genomic characters is diagnostic: cne7048.1.3: T2251C, cne3658.2.1:A638T, cne 2957.11.4:A952G, cne3658.2.1:A608C, and cne3461.2.10:C1462A.

Etymology. The name is a feminine noun in the nominative singular formed by replacing prefix "Meso-" with "Ecto-" in the name of the former genus for these species.

Species included. The type species, Mesosemia decolorata Lathy, 1932 , Mesosemia erinnya Stichel, 1910 , and Mesosemia steli Hewitson, 1858 .

Parent taxon. Subtribe Mesosemiina Bates, 1859 .
