Male genitalia
(
Figs. 7−10
): Uncus very broad, with nearly parallel sides, slightly triangularly narrowed to the top; branches of gnathos moderately thick, long, distally joined; tegumen moderately-sized; valva broad, smoothly сonverging to top, with moderately-developed sacculus; costal edge of valvae with semicircular apically directed procession situated on boundary of basal and mesial third of costal edge; top of costal edge with small procession directed perpendicularly to axis of edge; top of valvae rounded; juxta small, shaped as a lengthwise-split conical valley; saccus comparatively broad, stout, apically smoothly сonvergent; phallus nearly straight with slight bifurcation on coecum; aperture of vesica situated on dorso-apical side on a half of phallus length; vesica multipleshaped with long diverticulum and nearly evenly spaced band of needle-shaped cornuti, spreading to diverticulum from basal areas of vesica.
Female genitalia
(
Fig. 20
): Papillae anales conical; length of anterior apophyses nearly equal to length of posterior; aperture of ostium deeply-submerged, cup-shaped; ductus strongly sclerotized, broad; bursa small, bagshaped; ductus seminalis springing from junction of ductus and bursa; bursa without signum.
Bionomics and distribution.
The new species is known only from a few mountainous localities. The
type
locality is XilingXue Shan (Snow mountains) (
Figs 21−22
), at the eastern edge of the Tibetan plateau in the North West part of China's Sichuan Province. Several specimens were attracted to light from middle July to early August at altitudes ranging from
1150 to 3000 m
. The new species was collected in virgin mixed forest dominated by various broad-leaved trees such as oaks (
Quercus dentata
,
Q. glauca
), poplars (
Populus cathayana
,
P. simonii
), elm (
Ulmus parvifolia
), rhododendrons (
Rhododendron brachycarpum
,
R. dauricum
), and bamboos (
Phyllostachys
ssp.,
Borinda
ssp.,
Fargesia
spp.). The new species is sympatric there with
C. danieli
and
C.griseotincta
.
Adults are on the wing with many other typical summer moths, including
Haderonia albirena
(Draudt, 1950)
,
Xestia morandinii
Gyulai,
Ronkay & Saldaitis, 2011
,
Papersta florianii
Gyulai,
Ronkay & Saldaitis, 2011
,
Diarsia pelenai
Gyulai,
Ronkay & Saldaitis, 2011
(all
Noctuidae
).
Diagnosis.
The new species is most similar to three other Chinese species:
Catopta griseotincta
Daniel, 1940
(
Figs. 5−6
),
Catopta albothoracis
Hua, Chou, Fang & Chen, 1990
(
Fig. 19
) and
C. danieli
(
Fig. 3−4
). However, it clearly differs in wing pattern and genital structure.
Morphology:
C. albothoracis
and
C. danieli
each have broad areas of light hair on the thorax, vs. brown hair in
C. dusii
.
C. danieli
(
Figs. 15–18
) compared with
C. dusii
is larger (wingspan
47−50 mm
, vs.
31−42 mm
), has a uniformly convergent uncus vs. being constricted only in the distal third, valvae with a slightly-developed irregularity in the mesial third vs. a well-developed process, a broad rather than narrow juxta, and an asymmetrical phallus with triangular process on left edge of the vesica aperture vs.
C. dusii's
symmetrical phallus.
C. dusii
has dark grey-brownwing color with bluish suffusion, vs. typical light grey colored wings of
C. griseotincta
. In
C. griseotincta
(
Figs. 11−14
) vs.
C. dusii
the middle third of the dorsal surface of the phallus is covered by small spines vs. smooth (
Figs. 7−10
), the distal tooth of valveis displaced basally vs. a weakly developed tooth placed on top of the valve, the valve is more slender vs. a broader valve in the basal third, and the saccus is thin and long vs. broad and apically smoothly сonvergent. In the male genitalia of
C. albothoracis
(
Fig. 19
) the valvae have nearly smooth costal edges vs. with two processes in
C.dusii
, and a thin, long saccus vs. abroad, apically smoothly сonvergent saccus.
Etymology
. The species is named after Professor Stefano Dusi (Verona,
Italy
) for his contributions to entomology.
