Ancylosis ningxiana Li & Ren , sp. nov.
( Figs 9 View FIGURES 5–10 , 14 View FIGURES 11–15 )
Type material. Holotype ♂, CHINA, Ningxia: Shapotou, Zhongwei , 2.IV.1987, leg. GD Ren, gen. slide No. DYL01078.
Paratypes: 1♂, 5.V.1987, leg. GD Ren, gen. slide No. LJY11251, other same data as holotype ; 3♂, Yinchuan, Ningxia Agricultural Science Institute , 12.IV−28.VIII.1974, gen. slide No. DYL00281 .
Diagnosis. The new species is similar to A. fuscovenella ( Ragonot, 1887) , but can be distinguished by the forewing with the antemedial and postmedial lines present, which are absent in the latter; and in the male genitalia by the uncus obtusely rounded at apex, the valva with an obvious finger-shaped claspers, the narrowly banded sacculus about 1/2 the length of the valva, and the vinculum with the maximum width about 3/4 of its length and straight on the anterior margin. In A. fuscovenella , the apex of the uncus is pointed, the valva lacks claspers, the basally widened and distally narrowed sacculus is about 2/3 the length of the valva, and the vinculum is equal length to its maximum width and arched on the anterior margin.
Description. Adult ( Fig. 9 View FIGURES 5–10 ). Wingspan 26.0−31.0 mm.
Head. Vertex covered with rough brown scales.Antenna yellowish brown, scape twice as long as wide; flagellum with dorsal surface grayish white, ventral surface with dense cilia slightly longer than diameter of flagellum. Labial palpus obliquely upturned over head; segment II stout, grayish white mixed yellowish brown, 3 times as long as segment III; segment III grayish brown, extending forward.
Thorax. Mesonotum, patagia and tegulae grayish yellow mixed with dark brown. Forewing ground colour grayish brown, with a reddish brown band on anterior margin of discal cell reaching postmedial line; antemedial line grayish white, from basal 1/3 of costal margin to basal 2/5 of dorsum, forming a small Z-shaped fold from discal cell to CuA 1 vein, with a broad pale reddish brown edge on inner side posteriorly, with a broad dark brown edge on outer side; postmedial line grayish white, serrate, with an inward sharp angle at M 1 and CuA 1 respectively, edged with a wide dark brown line on inner side, yellow brown on outer side; two discocellular spots dark grayish brown, connected; terminal line dark brown; fringe grayish white. Hindwing gray; fringe grayish white. Legs grayish white mixed yellow brown; tarsus yellowish brown, ringed with grayish white at apex of each tarsomere.
Abdomen. Grayish brown, yellowish brown at end of each segment. Eighth sternum with anterior margin arched, posterior margin extended backward triangularly. One pair of culcita filiform, about 2/5 length of valva.
Male genitalia ( Fig. 14 View FIGURES 11–15 ). Uncus subovoid, 1.5 times as long as wide, apex rounded. Gnathos about 2/5 length of uncus, basal 1/3 inflated, narrowed distally, hooked apically. Transtilla short and small, sprout-shaped, about 2/5 length of juxta. Valva 5 times as long as wide, basal 3/4 parallel, distal 1/4 slightly narrow, apex obtuse; clasper digitate, with setae; costa reaching tip of costal margin, broadened basally, tapered distally, about 1/3 width of valva. Sacculus about 1/2 length of valva, narrowly banded. Juxta 1.5 times as long as wide; lateral lobes crescent. Vinculum with maximum width about 3/4 of its length, straight on anterior margin, slightly produced anterolaterally. Aedeagus about 4/5 length of valva.
Female unknown.
Distribution. China ( Ningxia).
Etymology. The specific epithet refers to the Ningxia Hui Autonomous Region, the type locality of this new species.
