Type species. Pardaleodes xanthioides Holland, 1892 .

Definition. A sister genus to Hollandus Larsen and Collins, 2015 (type species Pardaleodes xanthopeplus Holland, 1892 ), formerly placed in Paronymus Aurivillius, 1925 (type species Hesperia ligora Hewitson, 1876 ), but is not monophyletic with it ( Fig. 9 ). Keys to VII. 45.4 in Evans (1937) and differs from its relatives by narrow, beak-like uncus; tegumen narrowing into uncus gradually, their junctions slightly concave in ventral view; lack of gnathos; harpe gradually upturned, finely serrated at its short but nearly dorsal margin, with a tooth directed dorsad near its base; hindwing outer margin and tornus brown below. In DNA, a combination of the following base pairs is diagnostic: aly822.30.12:C365T, aly 1089.8.4:G53A, aly164.3.1:A811G, aly5294.20.2:A547A (not T), aly5294.20.2:A548A (not C), aly838.12.1: T458 T (not A).

Etymology. The name is a masculine noun in the nominative singular, fusion of the type species name with the genus name where it was placed previously: Xanth [ioides] and [Par] onymus.

Species included. The type species and Xanthodisca astrape .

Parent taxon. Tribe Astictopterini Swinhoe, 1912.
