Cryptolechia fustiformis sp. n.
( Figs. 2 View FIGURES 1–6 , 18 View FIGURES 17–24 )
Type material Holotype: ♂, CHINA: Mt. Tianmu (30 26'N, 119 34'E), Zhejiang Province, 1140 m, 17.viii.1999, coll. Houhun Li et al GoogleMaps . Paratypes: 7 ♂, 8 ♀, same data as holotype GoogleMaps .
This species is superficially similar to C. vespertina Meyrick but can be separated from it by the male genitalia: fustiformis has the uncus rodlike, the valva not dilated distally, and the aedeagus with a serrate cornutus.
Description Forewing length 13.0–13.5 mm. Head dark gray, frons yellowish white, shiny. Labial palpus white, covered with brown scales, except second segment black at apex and third segment black near distal end. Antenna with scape brown, flagellum scales alternating brown and brownish yellow. Thorax and tegula dark gray. Forewing with apex pointed, termen oblique; ground color brown, yellow along apex and termen; costal margin with yellowish spot beyond middle and at distal 1/5; single dark dot at middle, at end of cell, and near end of fold, sometimes indistinct; cilia whitish yellow, tinged with brown. Hindwing and cilia gray. Legs grayish white; fore and midlegs with tibiae gray on outside, tarsi with dark brown speckles; hindleg whitish, mixed with light brown on tibia and tarsus.
Male genitalia ( Fig. 2 View FIGURES 1–6 ): Uncus long and slender, straight, pointed distally. Tegumen short, wide. Valva knifeshaped, finely setose, rounded at apex; costa gently concave, with sclerotized edge. Sacculus short and broad, less than onehalf length of valva; apical margin strongly sclerotized, with spines, medially concave inward, forming rounded process ventrally. Saccus slightly shorter than sacculus, rounded anteriorly. Aedeagus short and strong, nearly as long as valva, distally spineshaped; cornutus a large spine, with several small spines along one side.
Female genitalia ( Fig. 18 View FIGURES 17–24 ): Papilla analis caudally rounded, with sparse short setae. Posterior apophysis about 2.5 times as long as anterior apophysis. Lamella postvaginalis finely setose. Ostium bursae short, wide funnelshaped, protruded dorsolaterally. Ductus bursae with posterior 1/3 sclerotized, anterior 2/3 membranous, 2.5 times length of corpus bursae. Corpus bursae small, rounded, spinulose inside; signum large, densely toothed, distally with a long, slender spine.
Etymology The specific name is derived from the Latin fustiformis (sticklike), referring to the shape of the uncus in the male genitalia.
Cryptolechia falsitorophanes sp. n.
( Figs. 3 View FIGURES 1–6 , 19 View FIGURES 17–24 )
Holotype: ♂, CHINA: Hefeng (29 53'N, 110 02'E), Hubei Province, 1260 m, 15.vii.1999, coll. Houhun Li GoogleMaps et al. Paratypes: 10 ♂, 1 ♀, same data as holotype except 15–16.vii.1999 GoogleMaps .
This species is similar to C. torophanes Meyrick but can be separated by the valva with the apex not rounded but slightly arched inward ventrally, and the transtilla absent in the male genitalia; ductus bursae sclerotized for entire length and corpus bursae without signum in the female genitalia.
Forewing length 11.5–12.0 mm. Head pale yellowish white. Labial palpus pale yellowish white, mixed with brown scales which are denser on outside of second segment. Antenna yellowish white; flagellum scales with brown rings. Thorax, tegula, and forewing grayish brown to dark brown, with scattered brown scales. Forewing lanceolate, with an inverted yellowish triangular spot at about distal 1/6; a broad yellowish fascia from costal 1/2 extending obliquely beyond middle of dorsum, medially set with two black dots on both sides; termen somewhat whitish yellow; cilia deep gray or dark brown. Hindwing and cilia pale brown. Legs whitish yellow, with brown speckles on tibiae and tarsi.
Male genitalia ( Fig. 3 View FIGURES 1–6 ): Uncus irregularly rectangular, setose. Tegumen narrow, more or less Vshaped. Valva narrowed at base, gradually widened toward apex, medially with a long sclerotized spinelike carina extending from base to apex (or nearly to apex); apex rounded, but emarginate ventrally. Sacculus about 2/3 length of valva, widest at base, narrowed to about middle; distal 1/2 narrow and curved, Sshaped. Saccus shorter than sacculus, anterior margin rounded. Aedeagus longer than valva, basal portion straight and sclerotized; vesica with a narrow, strongly sclerotized, incurvate band and a few spines.
Female genitalia ( Fig. 19 View FIGURES 17–24 ): Papilla analis sparsely setose. Posterior apophysis about twice as long as anterior apophysis. Lamella postvaginalis spinulate, hilllike in shape; posterior margin concave at middle, with long setae. Ostium bursae trapezoidal, caudal margin slightly concave at middle. Ductus bursae thick, entirely sclerotized. Corpus bursae small, rounded, anterior half densely speculate; signum absent.
Etymology The specific name is derived from the Latin falsus (false) and the name of another species, torophanes , referring to the similarity of the two species.
Cryptolechia luniformis sp. n.
( Figs. 4 View FIGURES 1–6 , 20 View FIGURES 17–24 )
Holotype: ♂, CHINA: Xinyi (22 21'N, 110 56'E), Guangdong Province, 1000 m, 7.viii.2003, coll. Dandan Zhang. GoogleMaps Paratypes: 7 ♂, 4 ♀, same data as holotype except 7–13.viii.2003 GoogleMaps ; 1 ♀, Shangsi (22 09'N, 107 58'E), Guangxi, 510 m, 6.iv.2002, coll. Shulian Hao and Huaijun Xue. GoogleMaps
Cryptolechia luniformis can be easily separated from all the other species of Cryptolechia by the forewing having a crescentshaped marking and the valva having three toothlike spines at the apex.
Forewing length 12.0–13.0 mm. Head with frons pale yellowish white, posterior area dark brown. Labial palpus pale yellow, densely covered with dark brown scales; third segment shorter than second, thin and pointed. Antenna black, flagellum scales with pale yellow rings. Thorax, tegula, and forewing dark brown. Forewing lanceolate, with two black dots at middle and end of cell, positioned one above the other; a broad crescentshaped whitish yellow mark extending from costal 2/5 downward to before tornus, then upward to costal 4/5, tinged with light brown scales; cilia dark brown, mixed with yellowish brown. Hindwing and cilia gray. Legs dirty white, with black speckles on tibiae and tarsi.
Male genitalia ( Fig. 4 View FIGURES 1–6 ): Uncus somewhat cylindrical, with long setae, posteriorly rounded. Tegumen narrowly banded laterally. Valva foliaceous, roundly dilated, narrowed, with a small process at base, bearing three small teeth apically. Sacculus widest at base, narrowed to about 2/3, distal 1/3 a large process with apex hooked upward. Saccus irregularly triangular, narrowly rounded anteriorly. Aedeagus slightly longer than valva, with a small round process near apex; vesica with two larger spines and a long sclerotized band.
Female genitalia ( Fig. 20 View FIGURES 17–24 ): Papilla analis broad, short, sparsely setose. Posterior apophysis about twice as long as anterior apophysis. Lamella postvaginalis widened, finely setose, with long setae along posterior margin. Ostium bursae relatively wide and short, like a pair of glasses. Ductus bursae heavily sclerotized. Corpus bursae large, longer than corpus bursae, constricted medially; signum absent.
Etymology The specific name is derived from the Latin luniformis (crescent), in reference to the shape of the conspicuous marking of the forewing.
