Torgus Grishin , new subgenus

http://zoobank.org/ 324B2041-EFAA-41BE-9403-70E49EF66BB9

Type species. Ouleus gorgus E. Bell, 1937 .

Definition. Instead of originating within the genus Eantis Boisduval, 1836 (type species Urbanus thraso Hübner, 1807 ) as previously assumed, members of this new subgenus form a lineage sister to all other Iliana E. Bell, 1937 (type species Iliana romulus Bell, 1937 ), but are separated from them by prominent genetic differentiation at the subgenus level ( Fig. 4 ). Therefore, they are placed in Iliana and a new subgenus is proposed for them. It keys to F.7.2 or F.7.5. in Evans (1953) and is distinguished from its relatives by the following characters: tegumen with longer side processes, harpe forked, not simply directed dorsal as in the subgenus Iliana , and ampulla not expanded. In DNA, a combination of the following nuclear genomic base pairs is diagnostic: aly315.4.2:A178C, aly1249.27.3:C34A, aly1249.27.3:A35C, aly806.12.1:C2122T, aly806.12.1:A1482G.

Etymology. The name is a masculine noun in the nominative singular, a fusion of the names of the two species placed in the genus: T [aurus]+[g] orgus.

Species included. Ouleus gorgus E. Bell, 1937 and Tosta taurus Evans, 1953 , for which we therefore propose new genus-species combinations: Iliana (Torgus) gorgus and Iliana (Torgus) taurus .

Parent taxon. Genus Iliana E. Bell, 1937 .
