Type material Holotype: ♂, CHINA: Shangsi (22°09'N, 107°58'E), Guangxi, 510 m, 6.iv.2002, coll. Shulian Hao and Huaijun Xue. GoogleMaps Paratypes: 2 ♀, same data as holotype GoogleMaps .

Diagnosis

Cryptolechia infundibularis can be distinguished from other species of the genus by the forewing pattern with three large ochreous marks, the valva with a strong thorn apically, and the antrum large and funnel­shaped.

Description Forewing length 17.5 mm. Head yellow. Labial palpus yellow with brown scales; brown scales becoming denser from 1/3 to end of second segment laterally. Antenna brown; flagellum scales alternating brown and yellow. Thorax, tegula, and forewing dark brown, with scattered ochreous scales, somewhat black in female. Forewing with apex pointed, termen distinctly oblique; large ochreous markings at costal 2/5, costal 1/5, and ventral 1/2, triangularly positioned; cilia ochreous tinged with brown, dark brown near apex and at tornus. Hindwing and cilia dark brown. Legs pale yellow, with large black speckles on tibiae and tarsi.

Male genitalia ( Fig. 12 View FIGURES 7–12 ): Uncus short, trapezoidal, broad at base, slightly narrowed to bluntly rounded apex; lateral margin sinuate. Tegumen short and broad, somewhat Cshaped. Valva narrow, densely setose in distal half; gradually expanded to about 2/3, then narrowed to apex, apically with a strongly sclerotized thorn. Sacculus short and broad, more or less oval, ventrally with a weakly sclerotized process at apex. Saccus almost as long as sacculus, rounded anteriorly. Aedeagus longer than valva, slightly narrowed basally; vesica distally with several thin twisted sclerites.

Female genitalia ( Fig. 28 View FIGURES 25–28 ): Papilla analis more or less cone­shaped, with long and short setae on margin. Posterior apophysis about 1/3 length of anterior apophysis. Lamella postvaginalis narrow, posterior margin concave mesally, and with long setae. Antrum large, funnel­shaped, sclerotized; anterior portion narrow, gradually widened toward posterior portion; posterior margin more than three times as wide as anterior margin, deeply concave mesally. Ductus bursae membranous, short, coiled. Corpus bursae elliptical, without signum.

Etymology This specific name is derived from the Latin infundibularis (infundibuliform), in reference to the shape of antrum in the female genitalia.

Cryptolechia similifloralis sp. n.

( Fig. 13 View FIGURES 13–16 )

Type material

Holotype: ♂, CHINA: Hefeng (29°53'N, 110°02'E), Hubei Province, 1260 m, 17.vii.1999, coll. Yanli Du and Zhendong Li. GoogleMaps Paratypes: 1 ♂, same data as holotype except 15.vii.1999 GoogleMaps ; 1 ♂, Tianquan (30°06'N, 102°46'E), Sichuan Province, 29.vii.2004, coll. Yingdang Ren. GoogleMaps

Diagnosis

This species is similar to C. argometra Meyrick in external characters but can be separated from the latter by having the forewing with the fascia gradually widened from the costal margin to the dorsum, the uncus somewhat wide rectangular, the valva with a small spine apically, and the aedeagus with several small, distinct, toothlike spines distally. Description

Forewing length 12.0 mm. Head with vertex brown, frons pale yellow. Labial palpus pale yellow except for second segment black at end, third segment densely covered with black scales. Antenna with ventral surface pale yellow, dorsal surface dark brown; flagellum scales dark brown and pale yellow. Thorax, tegula, and forewing dark brown. Forewing lanceolate, with an orange­yellow fascia extending from costal margin at about 2/5 length to dorsum at 2/3 length, gradually widened; weak black dot at middle of cell, end of cell, and middle of fold; costal margin with an orange­yellow dot at about distal 1/5; cilia grayish brown. Hindwing and cilia light brown. Legs yellowish white, tibiae and tarsi with dark brown speckles.

Male genitalia ( Fig. 13 View FIGURES 13–16 ): Uncus large, broad, somewhat wide rectangular, setose, about twice as long as wide; apex rounded. Tegumen a narrow, U­shaped band. Valva elongate, with fine setae, narrow at base, slightly widened to near apex; apex with a small spine. Sacculus about 1/2 as long as valva, concave mesally at apex. Saccus widest at base, greatly narrowed from about middle, apex narrowly rounded. Aedeagus strong, curved, distal margin with several small toothlike spines.

Female: Unknown.

Etymology The specific name is derived from the Latin simil­ (similar) and floralis (flower), in reference to the flowerlike distal part of aedeagus.

Cryptolechia trimaculata sp. n.

( Fig. 14 View FIGURES 13–16 )

Type material Holotype: ♂, CHINA: Mt. Wuyi (26°54'N, 116°42'E), Fujian Province, 600 m, 27.v.2004, coll. Haili Yu. GoogleMaps Paratype: 1 ♂, 1000 m, 26.v.2004, coll. Haili Yu.

Diagnosis

This species can be distinguished from other species of Cryptolechia by the three distinct orange­yellow spots of the forewing and the nearly parallel­sided valva in the male genitalia.

Description

Forewing length 15.0 mm. Head yellow, mixed with gray on vertex. Labial palpus pale yellow, except second segment black distally, third segment mixed with black scales, nearly as long as second, apex narrowly acute. Antenna yellow, flagellum scales alternating yellow and brown on dorsal surface. Thorax and tegula brown, tinged with yellow. Forewing brown, with dark brown dot at middle of cell, end of cell, and distal 1/3 of fold; yellow spot set on costa at 1/2 and 1/5 length respectively, another yellow spot situated at 2/3 length of dorsum, the largest of the three; cilia grayish brown. Hindwing and cilia gray. Legs pale yellowish white, with brown speckles on tibiae and tarsi.

Male genitalia ( Fig. 14 View FIGURES 13–16 ): Uncus relatively short, narrowed at about 1/4 length; distal 3/ 4 conical. Tegumen large, short. Valva narrow, nearly parallel­sided dorso­ventrally, only slightly dilated near distal 1/3; apex pointed. Sacculus broad, nearly elliptical, distal process thumblike, slightly curved. Saccus large, long, triangular, rounded apically. Aedeagus straight, basal 2/5 slender, distal 3/5 about 2.5 x width of basal 2/5; cornutus short, weakly sclerotized.

Female: Unknown.

Etymology This specific name is derived from the Latin trimaculatus (having three spots), referring to the forewing pattern.
