Catonidia lii Chen & He , sp. nov.

( Figs 11–20 , 34–36 )

Description. Body length (from apex of vertex to tip of forewing): 3 8.20–8.60 mm, forewing length: 7.15– 7.50 mm.

Coloration. General colour milk-white to fuscous ( Figs 34–36 ). Vertex fuscous, except anterior carina pale yellowish brown. Frons with basal half fuscous, lateral margins with four yellowish white markings, apical half and median carina pale yellowish brown. Clypeus pale yellowish brown, rostrum pale brown. Genae with basal part fuscous, apical part pale yellowish brown. Eyes blackish brown, ocelli pale yellowish brown. Antennae fuscous. Pronotum with anterior areas mostly fuscous, posterior region brown to fuscous, having several yellowish white markings, mesonotum pale yellowish brown, mesopleuron brown to fuscous. Tegula with inner half yellowish white, outer half brown. Forewing milk-white, with several brown spots, venation brown, apex of costal margin with brown to fuscous markings, apical cells each with a fuscous spot. Legs pale brown to brown. Abdomen brown.

Head and thorax. Head including eyes narrower than pronotum (0.55:1). Vertex wider than long in middle line (3.54:1). Frons longer in middle line than widest part (1.79:1), width at base narrower than width at apex (0.56:1). Pronotum longer in middle line than vertex (3.31:1). Mesonotum longer in middle line than pronotum (3.71:1), longer than pronotum and vertex together (2.79:1). Forewing longer than widest part (1.96:1). Spinal formula of hind leg 7–8–8.

Male genitalia. Anal segment longer than widest part about 2.28: 1 in dorsal view, apical margin broadly rounded ( Fig. 15 ). Pygofer in profile dorsal margin distinctly shorter than ventral margin, middle of posterior margin strongly angulated caudad ( Fig. 16 ), in ventral view medioventral process broad at base, lateral margins slightly converging apically, each with a small tooth at apical third, apical margin slightly concave medially ( Fig. 18 ). Genital style longer than width about 2.05:1, apical margin broadly rounded, with stout, twisted process rising from apical third of dorsal margin, inner side of base with slender, finger-like process ( Fig. 19 ). Phallobase tubular, in profile relatively narrow at base, dorsal lobe vestigial, small tooth-like, lateral lobes narrowing apically, curving dorsad, acute at apex; ventral lobe with basal half stalk-like, apical half broad and rounded, apical margin with several spines ( Fig. 20 ). Genital lamina sclerotized ( Fig. 20 ). Phallobasal conjunctival processes in profile strongly constricted at median third, expanded apical third, rounded at apex, each with an ear-like lobe at ventral margin and with a tooth at dorsal margin ( Fig. 20 ).

Type material. Holotype: 3, Jinshagou, Chishui National Natural Reserve (28°34´N, 105°42´E), Chishui County, Guizhou Province, China, 31 May 2000, Z.-Z. Li; paratypes: 1 3, Dongtang, Maolan National Natural Reserve (25°40´N, 108°05´E), Libo County, Guizhou Province, 25 May 1998, L.-M. Wang; 3 3, Xiannvdong, Dashahe Natural Reserve (28°53´N, 107°36´E), Daozhen County, Guizhou Province, 640m, 26 Aug. 2004, X.-S. Chen ( IEGU).

Etymology. This new species is named in honour of Prof. Z.-Z. Li, one of the collectors of the type specimens.

Host plant. Unknown.

Distribution. China (Guizhou Province) ( Fig. 40 ).

Remarks. This new species resembles C. emeiensis but differs from the latter in the lack of a large triangular fuscous marking on the apex of the forewing clavus.
