creamy yellowish, venter yellowish white with a pair of sublateral
narrow black stripes, valva with a median black stripe. Posterior
tibia creamy white, posterior half of upper edge with an expanded
tuft of scales, triangularly prominent at the beginning, rounded at
the end, pale gre3dsh ochreous, appearing grey in certain hghts.
Forewing sublanceolate, rather narrow. Creamy, with numerous
fuscous-gi'ey transverse strigulae, scattered all over the wing, except
along costa anteriorly; base of costal edge suffused with grey; an
inwards-oblique grey transverse mark from costa well beyond base,
dilated at the end, not reaching base of wing; plical stigma larger

ochreous, tinged brighter yellow along costa and around apex, opposite
apex tipped slightly with dark.
Hindwing semipellucent pale golden yellowish, veins deeper yellow.

The female posterior tibia (missing in the holotype) is covered with
roughly rising scales along anterior half, with a triangular dense tuft
well before apex and a rounded tuft at apex, in fact similar to that in
the male, but more infuscated above and beneath, with a broad dark
fuscous band including the triangular tuft. Spurs dilated by a fringe
of bristly grey scales along posterior edge.
Male genitalia rather differing from these of the type species, T.
torvella Walker. Tegumen similar, but less sclerotized, less narrowed
tops simply truncate. Vinculum moderate, annular; saccus very
long, slender. Valva semiconical, concave, broad at base, cucullus
narrowed, conical, rounded. Sacculus represented by a thin marginal
rod and a second ventral top of valva, with a large transverse filamentous
top. Costa of valva with a moderate triangular hairy
process. There is a slender process at the middle of the base of valva,
directed rostrad. Anellus moderately oval, forming a central tube.
Aedeagus extremely long and slender.
Female genitalia: Eighth tergite dilated, oval. Sterigma strongly
sclerotized and hairy, shaped as an inverted large W. Ostium small,
dilated at the top. Ductus and corpus bursae simple, unarmed, finely
transversely plicate.
