Type genus. Falga Mabille, 1898 .

Definition. An assemblage of genera previously placed in three subtribes ( Carystina Mabille 1878 , Anthoptina A. Warren, 2009 and Moncina A. Warren, 2008), the subtribe is characterized by the maximal statistical support values in all genomic trees ( Fig. 1 ) and is in the same clade with Anthoptina and Moncina. Keys to I.1, I.2, J.8, J.13., J.16c, J.31, J.47, J.49, or K. 1 in Evans (1955). The lack of spines on mid-tibiae is the unifying morphological character of this morphologically diverse group best diagnosed by the combination of the following synapomorphic DNA characters: aly 1186.4.1:A962T, aly48.2.12:C1493A, aly345.16.5:A563T, aly536.1.3:A312G, aly276378.18.1:A1489G.

Genera included. Falga Mabille, 1898 , Justinia Evans, 1955 , Thargella Godman, 1900 , Propapias O. Mielke, 1992 , Synapte Mabille, 1904 , Turesis Godman, 1901 , Flaccilla Godman, 1901 , Methion Godman, 1900 , Mnasinous Godman, 1900 , Miltomiges Mabille, 1903 , Methionopsis Godman, 1901 and a new genus described below.

Parent taxon. Tribe Hesperiini Latreille, 1809 .

Comments. This subtribe is yet another unexpected assemblage of genera with disparate morphology. However, its monophyly is very strongly supported in all trees ( Fig. 1 ). No phenotypic synapomorphy is apparent to unify these taxa, and the ultimate diagnosis is possible on the basis of synapomorphic DNA characters.

Figures

Figure 1. Genomic trees of representative Hesperiidae. The trees are built from protein-coding regions in different genomic partitions: a) Nuclear genome; b) Z chromosome; c) Mitochondrial genome. The trees are rooted with Pterourus glaucus (NVG-1670), not shown. See Table 1 and Table S1 in the Supplemental file deposited at https:// osf.io/5cfht/?view_only=21eb53b6f8f344afaee3de2be90bf5d2 for additional data about these specimens. Names of species placed in new tribes and subtribes described in this work are highlighted in yellow and clades representing new taxa are colored in red. Clades for tribes and subtribes where species of the new taxa were placed previously are colored in blue and green arrow points from the former taxon to the new taxon (only on nuclear genome tree). Statistical support values are shown by nodes in all but the COI barcode trees. COI barcode NJ dendrogram is given for comparison and is not expected to reflect phylogeny. Subfamilies, tribes and subtribes for species included in the trees are shown to the right of the nuclear tree. Sequenced specimens of the type species of the new tribes and subtribes are illustrated in dorsal (left) and ventral (right) views and indicated by blue arrows
