Cryptolechia proximihamatilis sp. n.

( Figs. 7 , 23 )

Type material

Holotype: ♂, CHINA: Baoxing (30°22 N, 102°50'E), Sichuan Province, 1100 m, 5.viii.2004, coll. Yingdang Ren. Paratype: 1 ♀, Tianquan (30°06'N, 102°46'E), Sichuan Province, 29.v.2004, coll. Yingdang Ren.

Diagnosis

This species is most similar to C. hamatilis in the male genitalia, but can be separated from it by the following characters: uncus cone­shaped, valva with a small spine at apex, apex not rounded but slightly concave near costa, and aedeagus slender, basal portion about 1/4 width of median portion.

Description

Forewing length 12.5 mm. Head yellow, mixed with gray. Labial palpus yellow, with scattered black scales; black scales denser in distal portion of second segment and in median portion of third segment. Antenna dark brown. Thorax, tegula, and forewing grayish black. Forewing lanceolate, with an inverted, triangular, orange­yellow spot at distal 1/5; an orange­yellow fascia extending from middle of costal margin to 2/3 length of dorsum, medially set with two small black dots along its inside and one elongate black spot along its outside; cilia dark gray. Hindwing and cilia dark gray. Legs whitish gray, with dark gray speckles on tibiae and tarsi.

Male genitalia ( Fig. 7 ): Uncus long, cone­shaped, setose. Tegumen short, wide, Vshaped. Valva broad, narrowed at base, dilated distally; apical margin with a small spine near costa, slightly concave from below the spine to about middle; a weakly sclerotized carina extending from base to beyond 3/5 at 3/5 width of valva, distally with a small toothlike process. Sacculus longer than tegumen+uncus, with basal half broad, distal half abruptly narrowed and curved, hooked distally. Saccus narrow, about 1/2 length of sacculus, narrowly rounded anteriorly. Aedeagus straight, slender, basal portion about ¼ width of median portion; vesica with curved, sclerotized and irregularly­shaped plates as well as a long, sclerotized, strong cornutus.

Female genitalia ( Fig. 23 ): Papilla analis short, broad, sparsely setose. Posterior apophysis about twice as long as anterior apophysis. Lamella postvaginalis slightly concave at middle of posterior margin. Antrum broad, margins more distant at base, as long as anterior apophysis. Ductus bursae membranous. Corpus bursae oval, with two small rounded signa.

Etymology The specific name is from the Latin prefix proxim ­ (near) and the specific epithet hamatilis , indicating the similarity of the two species.

Cryptolechia bifoliolata sp. n.

( Figs. 8 , 24 )

Type material Holotype: ♂, CHINA: Mt. Wuyi (26.54'N, 116°42'E), Fujian Province, 740 m, 17.v.2004, coll. Haili Yu. Paratypes: 2 ♀, same data as holotype except 19.v.2004 .

Diagnosis

This species can be distinguished from its congeners by the distally bifurcate uncus and triangular­shaped valva in distal 1/ 2 in the male genitalia, and the spinelike process arising from the posterolateral margin of the antrum in the female genitalia.

Description

Forewing length 16.5 mm. Head orange­yellow. Labial palpus orange­yellow, densely covered with black scales on outside of second segment; third segment about 2/3 length of second segment, with a black ring near apex. Antenna orange­yellow, flagellum scales with brown rings on dorsal surface. Thorax, tegula, and forewing grayish black. Forewing broadly lanceolate, with yellow spot at costal 1/2 and 3/4 and at tornus; cilia grayish brown. Hindwing and cilia brown. Legs yellow laterally, grayish brown medially, with pale yellow speckles at end of tibiae and distal portion of tarsi.

Male genitalia ( Fig. 8 ): Uncus slender, wide at base, gradually narrowed to about 1/4, then parallel­sided to apex; distal portion bifurcate, forming two lateral lobes. Tegumen more or less large trapezoidal. Valva triangular in distal 1/2, costa gently curved, with sclerotized edge, ventral margin medially projected outward. Sacculus large, broad, with apex truncated, roundly extended dorsally. Saccus relatively small, elongate, narrowly round at apex. Aedeagus with median portion slightly expanded, distal portion with several small toothlike spines along one side.

Female genitalia ( Fig. 24 ): Papilla analis relatively small, sparsely setose. Posterior apophysis about four times length of anterior apophysis. Lamella postvaginalis large, with long setae along posterior margin. Lamella antevaginalis extremely large, heavily sclerotized, subtrapezoidal, with large sclerotized spinelike process arising from posterolateral margin. Ductus bursae very short, basal half membranous, distal half widened and spiculate. Corpus bursae large, rounded, without signum.

Etymology The specific name is from the Latin bifoliolatus (bilobed), in reference to the distal shape of the uncus.
