( Figs 1–39 )

Catonidia Uhler, 1896: 281 ; Matsumura, 1914: 178; Chou et al., 1985: 28; Wang et al., 1990: 120; Emeljanov, 2005: 19.

Type species. Catonidia sobrina Uhler, 1896: 281 , by original designation.

Description. Body length (from apex of vertex to tip of forewings): 3 7.55–8.75 mm, forewing length: 6.60–7.50 mm.

Head and thorax. Head including eyes narrower than pronotum (0.55–0.62:1). Vertex wider at base than long in middle line (2.21–3.54:1), anterior margin carinate, broadly convex, lateral margins excavate, median carina distinct or obsolete ( Figs 1 , 11 , 21 , 31, 34, 37 ). Frons slightly convex in profile, lateral margins shallowly convex, carinate, median carina distinct, frons longer in middle line than widest part (1.79–2.0:1), narrower at base than at apex (0.56–0.84:1) ( Figs 2 , 12 , 22 , 32, 35, 38 ). Antennae subglobose. Pronotum longer in middle line than vertex (1.39–3.31:1), medially and laterally carinate, one complete ridge between eyes and tegula, median carina distinct, lateral carinae not attaining hind margin, posterior margin angularly concave. Mesonotum broad, tricarinate, longer in middle line than vertex and pronotum together (2.56– 3.00:1) ( Figs 1 , 11 , 21 , 31, 34, 37 ). Forewings longer than widest part (1.96–2.05:1), anterior margin slightly convex, apical margin deeply rounded, Sc+R and M forking one-seventh from base, Sc and R forking approximately one-third from base, M forking level to nodal line, Cu1 forking two-fifths from base just distad of union of claval veins, Sc with approximately seven supernumerary branches at margin, R with two branches at apex, M regular with five branches, Cu1a simple, Cu1b with two branches ( Figs 3 , 13 , 23 ). Hindwings broad, R with two branches, M with four branches, Cu1 with two branches ( Figs 4 , 14 , 24 ). Legs slender, post-tibiae unispinose, spinal formula of hind leg 7 (8)–8 (7 or 9)–8 (9).

Male genitalia. Anal segment in dorsal view relatively large, subrectangular, longer than widest part (1.75–2.28:1), widest at apical third, apical margin broadly rounded or slightly truncate ( Figs 5 , 15 , 25 ), in profile subparallel-sided at basal two-thirds, narrowing apically at apical third ( Figs 6 , 16 , 26 ). Anal style separated, situated after middle of anal segment, surpassing apical margin of anal segment. Pygofer ring-like, in profile dorsal margin very short, posterior margin with dorsal third angulated caudad acutely or roundly ( Figs 6 , 16 , 26 ), in ventral view medioventral process broad at base, apical margin slightly concave or rounded medially ( Figs 8 , 18 , 28 ). Genital styles in lateral view elliptic, apical margin rounded, a stout, twisted process rising from apical third of dorsal margin, inner side of base with a finger-like process ( Figs 9 , 19 , 29 ). Phallobase in lateral view tubular, dorsal and lateral lobes with anterior portions protruding cephalad into body cavity, apices not separated, lateral lobes broad at middle, narrowing apically, acute at apex, directed dorsad; ventral lobes in lateral view broad at middle, basal portion stalk-like, in ventral view rod-like, single, apex acute. Suspensoria suspended phallobase with dorsolateral portions of pygofer. Genital lamina sclerotized. Phallobasal conjunctival processes reaching slightly over anterior margin of pygofer, in dorsal view rod-like, straight, apical half diverging into two branches, apex rounded, each with an ear-like process at lateral margin near apex. Sheath extremely developed, broad, twisted and membranous. Connective relatively short ( Figs 10 , 20 , 30 ).

Host plant. Some species were collected from fruit trees such as peach, Prunus persica ; olive, Olea europaea ; loquat, Eriobotrya japonica , and orange, Citrus aurantium ( Wang et al. 1990; Wang et al. 1991).

Distribution. Oriental region ( China and Japan) ( Fig. 40 ).

Remarks. Emeljanov (2005) resurrected the genus Ouwea Distant, 1907 (= Spendon Jacobi, 1928 ) from synonymy with Catonidia Uhler and the only known species, type species Ouwea doddi Distant, 1907 (= Spendon flavonotatus Jacobi, 1928 ), was removed from Catonidia .
