SCOPARIA TRIBULOSA
LI
SP. NOV.
(
FIGS 1–2
,

,
4B
,
7A–B
)
Diagnosis
Very similar to
Scoparia uncinata
Li, Li & Nuss, 2010
and
S. longispina
sp. nov.
in the male genitalia capsule, but distinguished easily from the two species by the characters of cornuti: the new species with one spineshaped and two small thorn-shaped cornuti attached on a broad and short sclerotized plate in the phallus (
Fig. 4B
); in
S. uncinata
, the phallus only with a thin and long cornutus (
Li, Li & Nuss, 2010: 18
, figs 17– 18); in
S. longispina
sp. nov.
, the cornuti composed of a long spine and a shorter spine (
Fig. 4C
). This species is also similar to
Scoparia jiuzhaiensis
Li, Li & Nuss,
2010
in the whole impression of the female genitalia, but its signum and appendix bursae are well developed (
Fig. 7A–B
); in
S. jiuzhaiensis
, the signum and appendix bursae are absent (
Fig. 8C
).
Description
Adult (
Fig. 3B
):
Forewing length 8.0–9.0 mm. Frons and vertex white mixed with pale brown. Patagium, thorax, and tegula pale brown mixed with white. Forewing suffused with blackish brown scales; antemedian line lined with dense black scales on outer side, slightly convex near middle, curved inwards near dorsum; antemedian stigmata stripe-like; distal discoidal stigma 8-shaped; postmedian line waved, meeting costa and dorsum perpendicularly; subterminal line distinctively concave at middle, convex near dorsum; fringe white, pale brown near base. Hindwing white; fringe white, mixed with pale brown near apex. Abdomen grey.

are recorded, the coloured dots indicate the recorded localities and species numbers.
Male genitalia (
Fig. 4B
):
Uncus narrow at base, broadening towards middle, then tapering to blunted apex. Gnathos a bit shorter than uncus, pointed tip with small hook. Valva narrow at base, broadening towards rounded apex; costa with small process near base, conspicuously convex near middle. Sacculus gently concave at distal one-third of ventral margin. Juxta ovate. Phallus straight, about three-quarters as long as valva; one spine-shaped and two small thorn-shaped cornuti attached on a broad and short sclerotized plate.
Female genitalia (
Fig. 7A, B
):
Papillae anales nearly as long as apophysis posterior. Tergite 8 about onethird as long as apophysis anterior. Antrum tubular, about half as long as colliculum, covered with dense granules. Colliculum convex laterally, much thicker than posterior part of ductus bursae. Ductus bursae thin and long. Corpus bursae ovate, covered with dense spines on left side; signum well-developed, composed of small thorns of various size; appendix bursae ovate.

Etymology of specific epithet
From the Latin
tribulosus
(= tricuspid), referring to the cornuti that is tricuspid distally in the male genitalia.
Remarks
The female genitalia of this species varied in the characters of colliculum and corpus bursae: the colliculum of most specimens is conspicuously convex near the middle, the corpus bursae is covered with dense tiny spines on the left half, and bears a stripe-like signum on right area (
Fig. 7A
), but individual differences were shown by the colliculum slightly convex near anteri- or tip, the bursae covered with bigger spines on the left one-third, and the signum nearly ovate (
Fig. 7B
). The different characters can be confirmed to intraspecific variability based on the results of phylogenetic analysis, three
COI
sequences (DNA nos. L13067, L13068, and L13069) of the common female specimens and one
COI
sequence (DNA no. L13070) of the individual female specimen were represented by a well-supported cluster (
Figs 1
and
2
).
