Adult habitus.
General color brown to dark brown. Ocellar area covered by dark brown quadrangular spot and area forward of M‐ line with smaller triangular dark area (
Fig. 15
); occiput pale brown. Pronotum dark brown with scattered rugosities. Wings brown with pale costal area. Femora banded, pale basally and dark apically; tibiae dark brown.
Male.
Forewing length
20‐22 mm
.
T
5 produced into an emarginate lobe;
T
6‐9 with large mesal, membranous field covered with fine setae (
Fig. 16
). Projecting portion of hemitergum about twice as long as basal callus in dorsal aspect, gradually tapered to rounded tip in lateral aspect (
Fig. 18
). Aedeagus cylindrical, relatively straight and armed with microtrichia and small triangular spines over most of apical half (
Fig. 17
); apex terminating in a slender cylindrical lobe armed with fine brown setal spines; basolateral lobes absent.
Female.
Forewing length
24‐26 mm
. Subgenital plate covers most of sternum 9 and is slightly emarginate or entire on posterior margin (
Fig. 19
). Vagina constricted near midlength; accessory glands less than half as long as vagina (
Fig. 20
).
Egg.
Outline oval. Collar absent. Chorion smooth, similar to
T. canilimbata
.
Larva.
Unknown.
Remarks.
This species is known from southwest
China
, primarily from the
T. fortunati
and
T. grahami
21
22
type
series.
Sivec et al. (1988)
listed it as valid, but erroneously placed
T. canilimbata
as a synonym; had
T. canilimbata
and
T. fortunati
remained synonyms, the former species would have priority. As discussed above under
T. canilimbata
, these species are now regarded as distinct, primarily due to differences in leg banding patterns and distribution.
