Type species. Codatractus amazonensis Bell, 1947 .

Definition. A sister genus to Oileides Hübner, [1825] (type species Oileides vulpinus Hübner, [1825] ), where C. amazonensis was placed previously ( Fig. 2 ). However large genetic distance between O. vulpinus and O. amazonensis (COI barcodes differ by 12.3%, the difference is typically smaller than 10% for species within a genus) argues for their distinction. Keys to D. 9.4 in Evans (1952). Genitalia illustrated by Bell in his fig. 2 ( Bell 1947). Distinguished from its relatives by the following combination of characters: shorter than tegumen and broad uncus with small (not longer than wide) arms; prominent gnathos not shorter than uncus; valva gradually curved dorsad, ending with two pointed teeth; tuft of apricot-colored modified scales in a groove along the vein near the base of ventral hindwing in males; forewing with a macular white band from mid-costa to tornus. In DNA, a combination of the following base pairs is diagnostic: aly8661.4.1:A916G, aly10226.44.1:C1975G, aly709.1.2: T194 C, aly36556.1.1: T2416 T (not A), aly274.33.1:A188A (not G), aly82.28.5: T398 T (not G).

Etymology. The name is a masculine noun in the nominative singular, for the type species that resembles butterflies from the genus Celaenorrhinus known as “Flats” in some English-speaking countries.

Species included. Only the type species.

Parent taxon. Subtribe Oileidina Grishin, 2019.

Figures

Figure 2. Genomic trees of Eudaminae and representatives of other Hesperiidae subfamilies. The trees are built from protein-coding regions in different genomic partitions: a) Nuclear genome. b) Z chromosome. c) Mitochondrial genome; d) COI barcode. 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=21eb53b6f8f344afaee3de2be90bf 5d2 for additional data about these specimens. Where possible, taxa are ordered similarly to that in the nuclear genome tree. Names of species placed in new genera described in this work are highlighted in yellow and clades of these genera are colored in red. Clades for genera where these species were placed previously are colored in blue and green arrow points from the former genus to the new genus (only on nuclear genome tree). Names of genera resurrected from synonymy are highlighted in cyan. Names of genera that form new genus-species combinations proposed in this work are highlighted in magenta. 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. The same notations are used in Fig. 2–13.
