Du, Yanli, Song, Shimei & Yang, Ding, 2005, New species of Ceroprepes Zeller (Lepidoptera: Pyralidae: Phycitinae), with a key to Chinese species, Zootaxa 1082, pp. 57-64 : 58-61

Ceroprepes atribasilaris sp. nov.

( Figs. 1 , 9 )

Diagnosis. This new species can be distinguished by the very large wing­span, the black base of forewing, the very large and broad papillae analis, the finely sclerotized transverse wrinkles at the anterior half of the ductus bursae, the rather large and well sclerotized signum, and the small corpus bursae.

Description ( Fig. 9 ). Wing­span 26.0– 32.5 mm. Antennae with basal 2/3 yellowish white, terminal 1/3 fuscous. Labial palpus fuscous, upcurved, second segment as long as the third, 2.0–2.5 times as long as first. Maxillary palpus fuscous, aigrettelike, 0.5 length of second segment of labial palpus. Foreleg, midleg, and hindleg fuscous except trochanter, base of femur, and terminal end of tibia sprinkled white. Forewing large and broad, with fuscous ground color, costa and basal area black; the scale ridge blackish fuscous, near to the antemedial line and extended from hind margin to costa; antemedial line whitish, incurved at veins M2 and A, outer edge bordered by thin black line; postmedial line indistinct, gray, incurved deeply at M1; discal spots fuscous, connected as lunate. Hindwing semi­translucent, veins and fringe darker, cilia gray.

Female genitalia ( Fig. 1 ). Papillae analis long and broad, only slightly shorter than ductus bursae. Apophyses posteriores somewhat longer than apophyses anteriores. Antrum funnel­shaped, lateral sides with anterior 3/4 incurved, anterior margin only 1/3 as wide as posterior margin. Ductus bursae nearly as long as antrum, posterior 1/2 with dense micro­spines, anterior 1/2 with many finely sclerotized transverse wrinkles. Corpus bursae short, elliptical in shape, 1.7 times as long as ductus bursae and 2.0 times as long as its greatest width, signum large, nipple­like, at anterior 1/3 of corpus bursae. Ductus seminalis from posterior end of corpus bursae.

Type material. Holotype female, Yunnan: Xishuangbanna (22.0°N, 100.5°E), 1200– 1600 m, 20.07.1958, leg. Shuyong Wang. Paratypes: 1 female, Fujian: Mt. Wuyi (26.5°N, 116.4°E), 1800 m, 27.07.2000, leg. Shimei Song; 1 female, Sichuan: Mt. Emei (29.3°N, 103.2°E), 1800–1900 m, 28.07.1957, leg. Keren Huang.

Distribution: China (Sichuan, Fujian, Yunnan).

Etymology. The specific name refers to the black basal area of forewing.

Remarks. The new species resembles C. ophthalmicella (Christoph) in the finely sclerotized, transverse wrinkles of the anterior half of the ductus bursae, but can be distinguished by the large wing­span, the black base of the forewing, the short corpus bursae, and the large signum.
