Type species. Paratrytone barroni Evans, 1955 .

Definition. A possible sister to Falga Mabille, 1898 (type species Carystus jeconia Butler, 1870 ) and in a different subtribe from Vacerra Godman, [1900] (type species Hesperia litana Hewitson, [1866] ) ( Fig. 10 ). Keys to M.23.9. in Evans (1955). Diagnosed by large and broad square palpi that are longer than the head, 2nd segment longer than usual and directed forward rather than dorsad, and 3rd segment very small; hindwing with a middle straight cream band on both sides. Genitalia illustrated by Bell (1959, fig. 18): uncus shorter than tegumen, arms rounded, gnathos longer than tegumen, saccus is very short, almost vestigial, valva broadens caudad, harpe short, upturned, joint with ampulla, without teeth or processes ( Bell 1959). In DNA, a combination of the following base pairs is diagnostic: aly1603.20.1:G64A, aly84.28.1:C2633G, aly707.2.13:T749A, aly798.5.3:G284G (not A), aly291.21.2:T2561T (not G), aly102.6.2:G1936G (not A).

Etymology. The name is a feminine noun in the nominative singular, formed as a fusion of the species names: senior and junior synonyms referring to the Type species. Bar [roni + m] olla.

Species included. Only the type species.

Parent taxon. Subtribe Falgina trib. n., described above.

Comments. A genus with surprising phylogenetic placement that yet again indicates the value of DNAbased methods at the genomic scale, and instills confidence in the results due to the large datasets used for phylogeny reconstruction and highly confident nodes in phylogenetic trees.
