Type species. Atrytone (?) potesta Bell, 1941.

Definition. A sister genus to Oxynthes Godman, [1900] (type species Goniloba corusca Herrich-Schäffer, 1869 ) combined with Oeonus Godman, [1900] (type species Oeonus pyste Godman, [1900] ) and in the same clade with Lindra Evans, 1955 (type species Carystus simulius Druce, 1876 ) ( Fig. 13 ). Not monophyletic with Orthos Evans, 1955 (type species Eutychide orthos Godman, [1900] ), which is in a different subtribe ( Carystina Mabille 1878 ). Keys to L. 15.5 in Evans (1955). Distinguished from its relatives by a combination of the following characters ( Bell 1941). Antennae about 2/3 of costa in length, male no secondary sexual characters, wings unmarked dark brown above with shiny green hair-like scales in tornal area of hindwing (and on body), with cream spots below: on hindwing near its middle plus diffuse cream area in distal half of CuA 2 -1A+2A cell, small spots on hindwing in discal cell and as a postdiscal row in each cell between veins M 2 and 1A+2A. Male genitalia (see Bell 1941: fig. 3 for illustration) with uncus deeply divided, arms long (only slightly shorter than tegumen), parallel, near each other, penis widening terminally (nearly as wide as valva), bulky, with terminal spikes, valva nearly rectangular, sacculus without processes, harpe short (shorter than 1/3 of valva), angular, with a stout tooth pointed dorsad, separated from ampulla by a narrow notch. In DNA, a combination of the following base pairs is diagnostic: aly2874.22.9:G1030A, aly3512.12.2:T234C, aly 2811.6.1:T166C, aly1139.93.1:C452C (not G), aly862.12.2:A1755A (not C), aly5021.5.1:G1325G (not C), aly537.7.1:A181A (not G), aly2012.14.2:T317T (not C), aly577.34.1:A485A (not T).
