Type species Catonidia sobrina Uhler, 1896 , by original designation. Diagnosis Medium to large-sized achilids. Head concave apically, median carina present or absent, lateral margins excavate. Frons slightly convex in profile, lateral margins shallowly convex, carinate, median carina distinct. Antennae subglobose. Rostrum long, surpassing hind-coxae. Pronotum with median and lateral carinae, one complete ridge between eyes and tegula, median carina distinct, lateral carinae not attaining posterior margin, posterior margin angularly concave. Mesonotum broad, tricarinate, longer in midline than vertex and pronotum combined. Forewings broadened apically, costal margin slightly convex, apical margin deeply rounded, ScP+R and MP forking about 1 / 7 from base, ScP and RP forking approximately ⅓ from base, MP forking level to nodal line, CuA forking 2 / 5 from base just distad of union of claval veins, ScP+RA with approximately five to eight supernumerary branches at margin, RP with two branches at apex, MP usually with five branches, CuA1 simple, CuA2 with two to three branches. Hindwings broad, RP with two branches, Cu with two branches. Legs slender, post-tibiae with a lateral spine. Male genitalia with pygofer ring-like, in lateral view, dorsal margin short, posterior margin with dorsal third angulated caudad acutely or roundly; in ventral view, medioventral process broad at base, apical margin slightly concave or rounded medially. Anal tube longer than widest part, apical margin broadly rounded or slightly truncate. Anal style separated, situated beyond middle of anal tube, surpassing apical margin of anal tube. Phallobase symmetrical or asymmetrical, lateral lobes broad at middle, acute at apex, directed dorsad, apical margin pointed, obtuse, or truncated; dorsal lobes simple, short or degenerate, apical margin pointed or rounded; ventral lobes simple, basal portion stalk-like, apex acute or truncate. Phallobasal conjunctival processes tubular, symmetrical or asymmetrical, apex sharp, rounded or slightly concave in middle, with one or two ear-like processes at lateral portion near apex. Gonostyli in lateral view elliptic, stout twisted process rising from apical third of dorsal margin, inner side of base with finger-like process. Remarks This genus may be easily distinguished from other genera of Achilidae by the follow features: disc of vertex distinctly depressed; tegula without longitudinal carina; forewing broadened apically, ScP+RA with approximately five to eight supernumerary branches at margin; medioventral process of pygofer not branched; phallobasal conjunctival processes with apex not like a duck foot; sheath extremely developed, broad, twisted and membranous; gonostyli in lateral view elliptic, a stout twisted process rising from apical third of dorsal margin, inner side of base with a finger-like process.
