Coleophora ningxiana Li , sp. n.

( Figs. 2 , 8–10 , 15 )

Type material

Holotype: ♂, CHINA: Luhuatai [38 32’ N, 106 11’ E], Yingchuan, Ningxia Hui Autonomous Region , 4.v.1989, reared from Lycium barbarum Linnaeus , genitalia slide no. L96165 . Paratype: 1 ♀, 19.v.1988, same locality as holotype, reared from leaves of Lycium barbarum Linnaeus , genitalia slide no. L96470 .

Diagnosis

This new species is closest to Coleophora stegosaurus Falkovitsh and Coleophora mosasaurus (Falkovitsh) , but can be separated from them by the following: forewing with more distinct streaks; setal patches of terga elongate and arched; gnathos very short, pedunculi longer than half the length of the tegumen, the valvula elongate and constricted at middle, sacculus narrower with an oblique ventral margin, and its distal portion divided into two longer branches in the male genitalia; and a shorter spine of signum in the female genitalia.

Description

Adult ( Fig. 2 ).Wing expanse: ♂ and ♀, 14.0 mm. Head: White, mixed with pale brown medially. Frons and postocular scales pale brown. Labial palpus greyish white; second segment longer than diameter of compound eye, apex ventrally with small pointed tuft; third segment less than half the length of second, pointed distally. Scales of haustellum silvery white. Antenna with scape greyish white, rough­scaled anteriorly; flagellum alternating dark and white.

Thorax: Dorsum and tegula white. Forewing with upper surface white, with scattered dark brown scales becoming streaks especially along main veins; ventral surface light, brown except costal margin greyish white; cilia greyish white. Hindwing pale brown, cilia yellowish grey. Legs greyish white; inner surface tinged with brown.

Abdomen ( Fig. 10 ): First tergum with 42–62 spiniform setae; setal patches of second tergum elongate and arched, with 104–122 densely arranged spiniform setae. Male genitalia ( Figs. 8–9 ) with gnathos narrowly transverse oval, very short, with long arms. Tegumen broad, rectangular; caudal margin with an arched carina, weakly sclerotized; anterior margin gently concave; pedunculi relatively broad, longer than half length of tegumen. Transtilla short and broad, trapezoidal, with carina. Valva elongate, costa gently concave, ventral margin weakly sclerotized, indistinct, apex rounded, edged with setae. Valvula large, elongate, outer margin constricted at middle. Sacculus relatively narrow, elongate, sclerotized, almost as long as valva; ventral margin gently oblique upwardly, medially with a sclerotized carina, sparsely with stiff setae ventrally; distal portion divided into two branches pointing upward, branch longer than width of cucullus, apex slightly exceeding costal margin. Juxta irregularly trapezoidal, juxtal rods united, dorsal margin sclerotized and straight, distal 1/5 bent, apex rounded; annulus and lamina indistinct, nearly membranous; cornutus absent. Female genitalia ( Fig. 15 ) with papillae anales broad and short, with long setae. Posterior apophyses about as long as anterior apophyses. Sterigma rectangular, length equal to half width, caudal margin slightly concave at middle, densely lined with short bristles. Ostium bursae broad, nearly round, slightly longer than and half as wide as sterigma. Colliculum inconspicuous. Ductus bursae about twice as long as anterior apophyses, without spinulate section, anterior half gradually widened. Corpus bursae ovoid; signum strongly sclerotized, spinelike, with base longer than spine.

Biology Living on branches and leaves of wild and cultivated Lycium barbarum .

Distribution China: Ningxia Hui Autonomous Region.

Etymology

The specific name is derived from the type locality, Ningxia Hui Autonomous Region, where barbary wolfberry, Lycium barbarum , is an important plant in traditional Chinese medicine .
