Daming( 23.08°N, 107.14°E),  1250 m,  29.v.2011, leg. Linlin Yangand Yinghui Mou, genitalia slide no. LGE17282.   Paratypes. Guangxi Zhuang Autonomous Region: 2 ♂♂, 2 ♀♀, same data as holotype except  20–29.v.2011, genitalia slide nos. CYP11197f, LGE17283f, LGE 18836m.   Diagnosis.The species is most similar to  T. immaculata  sp. nov., and differences between the two are presented under the latter species. In the male genitalia, the shape of the uncus is unique within the genus, with its distal part narrowly elongated compared to that of congeners.   Description.Adult ( Fig. 51). Head: Vertex greyish brown or fuscous, frons creamy white. Labial palpus pale brown; apex of palpomere I fuscous on outer surface, apex of palpomere II often slightly tinged with fuscous on outer surface; palpomere III slightly longer than II, strongly mixed with grey. Antenna with scape creamy white except posterior margin fuscous; flagellum dark fuscous except basal half of dorsal surface creamy white to pale brown; male cilia as long as diameter.  Thorax: Dorsum and tegula pale brown except anterior 1/2 or 2/5 dark fuscous. Wingspan 9.0–10.5 mm; forewing ground color pale greyish brown, costa dark grey, base dark fuscous above fold, middle of wing often strongly suffused with grey or dark grey; two indistinct grey lines arising from outer margin of former greyish suffusion: upper line narrowly to broadly extending toward apex along anterior 1/3 of wing, broadened and smudged near apex, lower line extending along fold and broadened near tornus; fringe scales pale greyish brown. Hindwing grey; fringe scales pale greyish brown. Legs creamy white to pale brown; mid-tibia with a fuscous spot at distal 1/3; hind tibia broadly fuscous at middle.  Abdomen( Fig. 8): Male coremata nearly as long as sternum VIII; sternum VIII pentagonal. Male genitalia ( Fig. 70) with uncus widest near base, gradually narrowing to middle, then uniformly elongate to rounded apex. Gnathos hook moderately long, sharply pointed apically. Tegumen approximately 4 times as long as uncus; with numerous ampulliform tubercles situated at middle of ventral surface, each bearing a long seta ( Fig. 31). Valva slender, gradually narrowing from base to basal 1/3, then uniformly elongate to 2/3; distal 1/3 spatulate, rounded at apex. Anellus lobe elliptical, 1/7 length of valva, sparsely setose on inner margin; apical bristle longer than anellus lobe, curved inward. Juxta setose in distal 1/3 of inner margin, near base of valva slightly protruded. Vinculum simple, with posterior margin broadly convex. Saccus broad, sub-triangular, exceeding tegumen pedunculus. Aedeagus with basal 1/2 globular; distal 1/2 slender, straight or curved downward. Female genitalia ( Fig. 88) with papillae anales simple and setose. Apophyses anteriores 1/2 length of apophyses posteriores. Tergum VIII divided into two sclerites; sternum VIII produced anteriorly, with two sub-triangular flaps covering ostium bursae. Ostium bursae near anterior margin of sternum VIII. Ductus bursae narrow at base, then gradually widening toward corpus bursae, ductus seminalis arising from posterior 1/3 of ductus bursae. Corpus bursae ovate, approximately 1.5 times as long as ductus bursae; signum small, slender, somewhat elongate fusiform, situated near entrance of ductus bursae.   Distribution. China( Guangxi).   Etymology. The species name is derived from the Latin isabellinus(isabelline), referring to the pale greyish brown forewing coloration. 3427696380 LGE17282 2011-05-29 Linlin Yang & Yinghui Mou China 1250 23.08 Mt.
