Genus Burnsius Grishin, 2019

Type species: Syricthus [sic] communis Grote, 1872 .

ZooBank registration: 48996B74-3AB1-4DEA-9A64-B8F112E62343

Diagnosis: The genus was defined as a clade from about 10 Mya that contains the species Syricthus [sic] communis Grote, 1872 , and putatively synapomorphic DNA characters for this clade were given ( Li et al., 2019). Phenotypically, species in this genus would key to G.1.5, G1.8, or G.1.10a in Evans (1953). Similar to Pyrgus and Chirgus in checkered appearance, produced wings: forewing costa longer than outer margin, hindwing costa about the same length as outer margin, short extensively scaled palpi with inconspicuous 3rd segment, but differ in the following characters ( Fig. 23 ): forewing with a white spot at the base of cell CuA1-CuA2, hyaline spots in cells R5-M1, R4-R5, R3-R4 not produced into cell R2-R3, and (1) if cell R1-R2 without spot between the apical spots and discal cell spot, then forewing with hyaline dot at base of cell R3-R4 between apical spots and discal cell spot, but (2) if no such dot, then hindwing outer margin evenly convex, not produced apically and white bar at the end of discal cell absent both above and below; or (3) if cell R1-R2 with hyaline spot by the costa midway between the cell spot and apical spots, then forewing with pale streaks marginally from the forewing discal cell spot and discal spots in cells M1-M2 and M2-M3.
