Type species. Proteides balenge Holland , 1891.

Definition. Currently, Gretnini Grishin, 2019 is a monotypic tribe consisting of a single genus Gretna Evans, 1937 ( type species Hesperia cylinda Hewitson, 1876 ). Inspection of genomic trees reveals that Grenta balenge ( Holland, 1891) ( type locality in Gabon) is strongly differentiated genetically from the Distant, 1886 ( type species Isma obscura Distant, 1886 ) from Iambrix Watson, 1893 ( type species Nisoniades salsala F. Moore, 1866 ) or Hyarotis F. Moore, 1881 ( type species Papilio adrastus Stoll, 1780 ) from Quedara Swinhoe, 1919 ( type species Quedara comoplea Swinhoe, 1919 ) and is at the tree level corresponding to genera. Therefore, the lineage with G. balenge represents a genus-level taxon ( Fig. 49). This new genus keys to 57.B. in Evans (1937) and is distinguished from its relatives by the subapical forewing spot in cell R 5 -M 1 being offset distad from others, uncus with processes at its base directed sideways (one on each side, no processes in Gretna ), and deeper separation between harpe and ampulla that is more expanded than in Gretna . A combination of the following COI barcode base pairs is diagnostic: T206C, A494T, A520C, A562C, A586T.

Etymology. The name is a feminine noun in the nominative singular, formed from the type species name.
