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.
