Type species. Rhinthon bushi Watson, 1937 .

Definition. A genus in the same clade with Neoxeniades Hayward, 1938 (type species Neoxeniades musarion Hayward, 1938) and far removed from Rhinthon Godman, [1900] (type species Proteides chiriquensis Mabille, 1889 treated as a junior subjective synonym of Hesperia osca Plötz, 1882) where it was previously placed, but does not belong (Fig. 10) in agreement with Burns et al. (Burns et al. 2010) and Smith et al. (Smith et al. 1994), who also questioned its position in Rhinthon but did not propose a proper genus for it. Keys to L. 8.2 in Evans (1955). Distinguished from all other Hesperiidae by unique pattern in the basal half of brown ventral hindwing consisting of five spots: three connected, silvery-white, the one in the distal half of discal cell framed yellow, and two others towards tornus, and two small yellow ones, near the base of the cell and past it; and orange fringes in tornal area of both wings, dark brown elsewhere. In DNA, a combination of the following base pairs is diagnostic: aly2487.23.1:C242G, aly13410.9.1:G2107T, aly2700.17.1:G706A, aly 1407.7.6:A2449C, aly 1283.9.1:A694G.

Etymology. The name is a masculine noun in the nominative singular meant to suggest the incredibly unique looks of this awesome skipper with icy patches on the hindwing below.

Species included. Only the type species.

Parent taxon. Subtribe Carystina Mabille 1878 .
