摘要：记述采自中国江西武夷山优苔螟属 Eudonia 1新种，即截形优苔螟 Eudonia abrupta sp. nov.。该
种与伊诺优苔螟 E. inouei Sasaki, 1998 近似，但其雄性外生殖器爪形突的末端与基部等宽，阳茎为抱器
瓣长的 1.5 倍；而伊诺优苔螟的爪形突末端显著窄于基部，阳茎与抱器瓣近等长。文中提供了成虫和外
生殖器特征图。模式标本保存在江西农业大学昆虫标本馆。

Introduction
The genus Eudonia Billberg occurs worldwide and contains 261 described species (Nuss
et al. 2003–2012). Members can be recognized by the long and thin costa, the absence of free
distal process and cornutus in the male genitalia; the long and thin apophysis posterior and
apophysis anterior, the elongate colliculum and the presence of appendix bursae in the female
genitalia. To date, 25 species of this genus have been known in China (Li et al. 2012). In the
present paper, one new species is described.
Terminology for morphological structures follows Nuss (2005). Genitalia were prepared
and mounted according to the methods introduced by Li (2002). The image of the adult was
taken with a digital camera Canon G12. The illustration of the genitalia was prepared with a
digital camera DV320 OPTPro2010_Chs attached to a digital microscope Optec BK-DM320.
The studied specimens are deposited in the Insect Museum, Jiangxi Agricultural University,
Nanchang, China (JXAUM).

Eudonia abrupta sp. nov. (Figs. 1, 2)
Forewing length 7.0–7.5 mm. Frons blackish brown. Vertex pale brown mixed with white.
Labial palpus blackish brown, dorsally white mixed with pale brown. Maxillary palpus
blackish brown, inner side and apex white. Antenna pale brown and white alternately on dorsal
surface, orange yellow on ventral surface. Patagium pale brown mixed with white. Thorax
blackish brown. Tegula pale brown mixed with white, posterior margin with long white scales.
Forewing covered with blackish brown scales; antemedian line white, outcurved at anterior
two fifths, incurved at posterior two fifths; antemdian stigmata stripe-shaped, blackish brown;
distal discoidal stigma 8-shaped, blackish brown; postmedian line white, sinuate, outcurved at
anterior two fifths; subterminal line white, straight, inconspicuous; fringe greyish white, pale
brown near base. Hindwing white, sparsely suffused with pale brown scales along costa,
terminal part and veins; fringe greyish white. Legs white, covered with blackish brown scales
on outer side, tarsi with blackish brown and white alternately on outer side.
Male genitalia (Fig. 2): Uncus convex slightly at basal half, concave at distal one fourth,
apex as wide as base, truncate distally. Gnathos broad basally, tapering to pointed tip, about
five sixths length of uncus. Valva narrowed near base, then broadened slightly towards distal
one fourth, distal one fourth narrowed to rounded apex. Juxta broad basally, narrowed towards
blunt apex. Phallus straight, one and half times as long as valva.

Female. Unknown.
Holotype. ♂, China: Jiangxi, Wuyishan (27°52′N, 117°47′E), alt. 1820 m, 08-VI-1991,
collector unknown, prep. gen. LW11034. Paratype. 1 ♂, same data as the holotype.
Diagnosis. This new species is similar to Eudonia inouei Sasaki, 1998 by the uncus with
a truncate apex in the male genitalia. It can be distinguished from the latter by the apex of
uncus as wide as its base, the phallus one and half times as long as valva in the male genitalia.
In E. inouei, the apex of uncus is much narrower than its base, and the phallus nearly as long
as valva.
Etymology. The specific epithet is derived from the Latin abruptus (= truncate) in
reference to the truncate apex of uncus in the male genitalia.
