Ceroprepes jilongensis sp. nov.

( Figs. 2–5 , 10 )

Diagnosis. The genitalia of C. jilongensis are very similar to those of C. patriciella Zeller in the short lateral arms of the juxta in male and the small, almost round corpus bursae in the female. The two species can be separated by the following characters: 1) the scale ridge on the forewing extends from the hind margin almost to the costa in C. jilongensis , but is absent from the costa to the upper edge of the discoidal cell in patriciella ; 2) the signum is small with no micro­spines on the inner surface of the corpus bursae in C. jilongensis , whereas the signum is large and the corpus bursae has many micro­spines in C. patriciella .

Description ( Fig. 10 ). Wing­span 24.0–28.0 mm. Antennae fuscous. Labial palpus fuscous, upcurved above vertex; second segment as long as third, 2 times as long as first. Maxillary palpus squamous, nearly as long as second segment of labial palpus. Forewing broad, with ground grayish dirty white; scale ridge blackish fuscous, distant from antemedial line, extending from hind margin almost to costa; antemedial line whitish, wavy, at basal 2/5 of wing, basal edge with a yellowish fuscous stripe proceeded by a row of reddish fuscous scales; postmedial line whitish and wavy, incurved at veins of M1 and A, excurved at middle. Discal spots blackish fuscous, separated from each other. Hindwing translucent and whitish, veins darker, cilia white.

Male genitalia ( Figs. 3–5 ). Uncus triangular, longer than the greatest width, apex narrowly rounded. Gnathos 2/3 as long as uncus, with basal 2/3 wide, terminal 1/3 thin, apex bifurcate. Transtilla saddle­shaped, similar to C. guizhouensis Du, Li & Wang. Base of valva as wide as tip, with digital protuberance near sacculus; terminal end of valva broadly rounded. Juxta short, about 1.4 times as long as gnathos, lateral arms separate each other from base, apices of lateral arms blunt. Vinculum U­shaped, shorter than greatest width. Aedeagus cylindrical, apex with micro­spines.

Female genitalia ( Fig. 2 ). Papillae analis large and broad. Apophyses anteriores as long as apophyses posteriores. Antrum funnel­shaped, lateral sides incurved, posterior margin more than 2 times wider than anterior margin. Ductus bursae about 1.4 times as long as antrum, inner surface with sparse micro­spines except anterior 2/3 of one side with dense micro­spines. Corpus bursae somewhat oval­shaped, 2.5 times as long as ductus bursae, 1.3 times as long as greatest width; signum small, nipplelike, located at anterior 1/ 4 of corpus bursae, remote from ductus bursae. Ductus seminalis from posterior end of corpus bursae near ductus bursae.
