Figs 36–47
Diagnosis
Salient features of new species include: forewings (Figs 36–37) transverse veins of costal area grayish white, radial and medial areas with 6 clear brown spots; dorsal lobe of phallobase (Fig. 45) long spiny, lateral lobes transected at apex, curled into inverted hooked process along ventral margin at end, ventral lobe short, middle to apex knife shaped, apical margin blunt, lateral sides with a lamellar process at the basal ⅓.
Etymology
The specific epithet is derived from the Latin word ‘ uncinatus ’, referring to the lateral lobes of the phallobase being curled into an inverted hooked process along the ventral margin at apex.

CHINA – Yunnan Province • 1 ♂, 1 ♀; Xishuangbanna National Natural Reserve; 22°02′ N, 100°90′ E; 28 Jul. 2012; Wei-Cheng Yang and Zhi-Min Chang leg.; IEGU.
Description
MEASUREMENTS. Body length including forewing: male 8.1–9.3 mm (N = 2), female 8.7 mm (N = 1).
COLORATION. General color yellowish brown (Figs 36–37). Vertex, base of frons and pronotum fuscous. Eyes reddish brown, ocelli light red. Posterior of pronotum milk-white. Tegula light yellowish brown. Forewings yellowish brown, large number of unclear grayish brown and dark spots distributed along veins, transverse veins of costal area grayish white, radial and medial areas with 6 clear brown spots, veins yellowish brown. Hindwings nearly hyaline, veins pale grayish brown. Legs and abdomen yellowish brown.
HEAD AND THORAX. Head (Figs 36, 38) including eyes narrower than pronotum (0.6: 1). Vertex wider than long in middle line (2.7: 1), apex concave, median carina absent, anterior margin angular, posterior margin subangular concave, lateral margins ridged, nearly parallel. Frons (Fig. 39) longer in middle line than maximum width (1.5: 1), width at base narrower than width at apex (0.6: 1), median carina distinct, lateral margins concave. Postclypeus (Fig. 39) shorter in middle line than frons (about 0.7: 1), median carina distinct, lateral margins excavate. Pronotum (Figs 36, 38) longer in middle line than vertex (2.4: 1), median carina distinct, lateral carinae raised, not extending to posterior margin, confluent with midline at anterior margin to form angular process. Mesonotum (Figs 36, 38) about 3.7 × as long as pronotum in midline, longer than pronotum and vertex combined (2.4: 1), basal of median carina present clearly, lateral carinae unclear. Forewings (Fig. 40) broadened apically, longer than maximal width (2.1: 1). Hindwings (Fig. 41) longer than widest part (1.5: 1).
MALE GENITALIA. Pygofer (Figs 42–43, 46) in lateral view with dorsal margin distinctly shorter than ventral margin, ⅓ of posterior margin strongly angulated caudad; in ventral view, apical margin of medioventral process concave medially. Anal tube (Figs 42, 46) longer than widest part by about 1.5: 1 in dorsal view, apical margin broadly rounded, basal margin narrow, slightly constricted near base. Aedeagus (Fig. 45) symmetrical, in lateral view, phallobase narrow at base, dorsal lobe long spiny; lateral lobes transected at apex, curled into inverted hooked process along ventral margin at apex, ventral margin of hook process with small process in the middle; ventral lobe shorter, basal part constricted into stalk, middle to end knife shaped, apical margin blunt, lateral sides with lamellar processes at basal ⅓; apical margin of phallobasal conjunctival processes wide and rounded, lateral sides each with long and large lamellar process along dorsal and ventral margin at subapical area. Gonostyli (Figs 42, 44) longer than wide, base narrow, apical margin broadly rounded, dorsal margin with stout twisted process near middle, inner side of base with slender, finger-like process.
Distribution
China (Yunnan province) (Fig. 47).
Remarks
This species is similar to Catonidia wuyishanana Wang & Huang, 1990, but differs from the latter as follows: (1) radial and medial areas of forewing with 6 clear brown spots (radial and medial areas of forewing without 6 clear brown spots in C. wuyishanana); (2) lateral lobes transected at apex, curled into an inverted hooked process along the ventral margin at apex (lateral lobes acute at apex, without inverted hooked process along the ventral margin at apex in C. wuyishanana); (3) apical margin of ventral lobe blunt (apical margin of ventral lobe acute in C. wuyishanana).
