Type species. Apaustus argyrosticta Plötz, 1879.

Definition. A sister genus of Ceratrichia Butler, [1870] (type species Papilio nothus Fabricius, 1787), where these species were formerly placed, but separated from it by a prominent genetic distance consistent with how other genera are defined (Fig. 9). Keys to VI.31.B in Evans (1937) and differs from its relatives by pale apical spot on ventral hindwing in cell R 5 -M 1 is in line with the spots in cells next to it (not offset strongly basad); uncus bulbous in ventral view, which gives tegumen with uncus a bowling duckpin shape; harpe widening distad, separated from ampulla; ventral hindwing ochreous with many small silvery spots, dorsal forewing brown with large orange-yellow spots. In DNA, a combination of the following base pairs is diagnostic: aly669.9.1:A231G, aly214.13.5:A98G, aly4389.5.1:G869A, aly 1329.4.13: T479 C, aly214.13.5:A97C.

Etymology. The name is a feminine noun in the nominative singular, a fusion of the Latin words Arg [entum] (silver) and [g] emma (jewel), for the shiny, silvery gem-like spots on the hindwing below.

Species included. The type species, Ceratrichia aurea Druce, 1910, Ceratrichia maesseni Miller, 1971, Ceratrichia mabirensis Riley, 1925, and Ceratrichia bonga Evans, 1946.

Parent taxon. Tribe Ceratrichiini, trib. n.
